Good.......2007-09-23
It works fine, and I got it just in time. It was just as it was advertised.
It Does the Job.......2007-09-23
I have been using the TI-83 plus for about three weeks now and I wouldn't go to my MA103 class without it. It does the job and is more affordable than some of it's other counter parts. All in all I recommend it, but if you will be going into much lengthier math studies in later years you may consider spending the extra money on the better versions of the TI series.
This is a Great calculator.......2007-05-29
I been using thsi calculator since I was a freshman in college. I used it for Math Modeling and Statistics. I did good in both of those classes because of my calculator. I am about to use it for Chemistry. The batteries last long and the calculator can be used for any math or science class. It was worth the money to buy it brand new.
This is a scientific calculator, so, READ THE MANUAL..........2007-05-14
It is not as easy as the TI-86 I had in 2000, it is better than the TI-83.
In 2000, I had a great professor in Statistics I. He broke the manual down, of the TI-86, into 30 pages of simple English, and, I "got it" on how to work it. This manual is a little more complicated and assumes that you know the stuff already. They forget that their market is- those who DON'T know how to already, they're students!
So, here's what you do. Set aside a day, yes, A DAY, to read and understand the manual. BUY IT BEFORE CLASS STARTS!!! If you can, buy your textbooks early too and PRACTICE IT! If you do, you will be spared what I went through.
All and all, it is a great product that I reccommend, but, you have to practice on it!!! GOOD LUCK!
ti-83+ pretty good.......2007-03-18
I'm not really 13, but don't have an account anyways. It's good because it has a large user base and well does some things okay. It can do most level 1 calculus things. Don't expect it to go farther than the high school level. Although it seems crappy (kinda of is comparted to ti-89 T) and a little to expensive, (it kinda is), it does its job well and has plenty of user made games and programs that excel the functionality of this calculator. This guide lasted me 6 years, well until the battery spring crapped up. I dropped in dozens of times on hard concrete and accidentally kciked it while picking it up and does fine. So anyways here are some key functions:
2-d graphing, numerical integration, summations, numerical derivatives, calculates slope, area under a cure graphically, BASIC programming editor, all functions found of scientific calcs, Matrices, linking, applications, some other stuff, Lists, just a lot of stuff, solver, polynomials.
Downloadable: 3-d graphing, calculation of pi to thousand digits or so, grayscale games, world map, symbolic differentiation, formulas, etc. and sound files.
This is not a really powerful calc, if you want something that will last you, I suggest a ti-84 + SE. It's 2.5x faster, 9x the memory, has a clock, looks cooler, (bad key contrast though), nice screen, usb connectivity, just a bunch of cool stuff.

It works!.......2007-09-22
Great calculator. May be a little much if you're not "dabbling" in derivatives. This thing is like a palm pilot on steroids.
Awesome Calculator.......2007-09-14
I have not had a chance to use some of the functions on this calculator. But, the ones that I have used, make it a superior calculator compared to any others I have ran across. The "pretty print" function allows you to see if you entered the problem correctly, which has caught some of my mistakes.
Great calculator, and I'm sure I won't need a more powerful one in my academic career
Ti-89 vs. Ti-89 Titanium.......2007-09-07
i`m a physics and engineering student and I've used both, ti89 and ti89 titanium several years and i still prefeer my ti89. Titanium is heavier and the feel and touch of the buttons is far better in the ti89. The only difference between both is the disk space available, software and display are exactly the same and unless you think you are going to have all the programs and notes of your entire carrier you dont need all the disk space in the titanium, i`ve never had space problems with the ti89 and i have all the programs i need uploaded.
Calculus Useage - High School.......2007-09-06
Overall, this is a pretty good calculator. However, it should be noted that it does take some time getting used to, especially when switching from a TI-83. The graphs are exceptional and there are many new options. Actually the amount of things it can do is both exhilerating and frustrating at the same time. One negative point is that when you enter in a simple calculation, like 734/87, it will NOT give you the decimal answer and will just leave it in fraction form. I hate that. Therefore, simple calculations are no longer simple on here.
This calculator is a life saver..........2007-09-01
This calculator is a life saver. It does a lot of different computations very easily using many different built in functions. One specific problem I have found is that, although it has option for doing intergration it sometimes does it right and sometimes it does it wrong, depending on the complexity of the equation. For example it consistently did wrong integration for PDE's wave equations. So, i had to do it by hand since i couldn't tell when it was right and when it was wrong. But over all its a great calculator.

Amazon.com Review
There are many inexpensive scientific calculators on the market, but few boast the two-line display and other advanced features users get with the TI-30x IIS. The display shows the equation you are creating on the top line, and the numbers or symbols you are currently entering on the second line. Once the equation is solved, the results are displayed on the second line, and you can use the four arrow keys on the front of the calculator to edit the original equation in any way you like for a recalculation. Better still, pressing the up arrow repeatedly lets you browse through a cache of dozens of previous calculations, meaning you can look back to see the answer to a problem you solved two minutes ago, two days ago, or whenever.
The device uses solar power when possible but can fall back on the internal batteries (which are included) if there isn't enough light. The buttons wiggle around a little too much and require a firm keystroke to register input, but the fact that input can be followed by looking at the output on the first line helps to cut down on mistakes. There is a shift key that doubles the functions of most buttons, and although the TI-30X IIS isn't festooned with as many buttons or functions as some other calculators we've tested in this price range, it's still very capable. There are three angle modes (degrees, radians, and grads), scientific and engineering notation modes, and even one- or two-variable statistical modes. Five variables can also be assigned to their own memory slots. The documentation is lacking, as everything is presented on a single folded sheet of paper, but Texas Instruments did manage to pack several illustrated examples on the page. The calculator comes with a snap-on cover that fits on the back of the device when you are using it. The calculator carries a one-year limited warranty. --T. Byrl Baker
Pros:
- Two-line display
- Relatively inexpensive
- Handles one- and two-variable statistical calculations
Cons:
- Weak documentation
- Buttons wiggle a bit too much
Amazon.com Product Description

Good calculator, flimsy case.......2007-09-14
This calculator has all the functions I need for a graduate level statistics class. I especially like the 2-line display, which makes it easy to type in long strings of numbers without forgetting your place. The only reason I failed to give this calculator 5 stars is the case. It is incredibly flimsy and leaves me with no sense of certainty that the calculator is safe bouncing around in my bag.
Great, Standard Scientific Calculator.......2007-09-05
When I was taking courses in calculus and physics, I used the TI-86 because it had more functions and was more powerful, for the kind of math that was needed.
However, the TI30XIIS is an excellent scientific calculator. It has most of the functions of a scientific calculator, with the scrollable screen that lets you check your numbers before multiplying, and perform many operations using the "Ans" function. As an organic chemist, it's the only calculator I need when it comes to doing simple chemistry calculations, which involve a lot of basic operations.
If you need to do derivates, integrals, polynomials, etc, then you should get something more powerful. If you just want a calculator to do your basic math yet allow you to check your numbers with ease, then this is a great calculator to have.
A Classic is Reborn.......2007-07-27
I purchased my first TI-30 in 1977 and carried in a drop holster with my slide rule, mechnacal pencils, and technical drafting pens. As the years went foward I retired on variant of the TI-30 for the latest, and every few years upgraded as I progressed in my profession.
The TI-30 has been an asset to the engineering business since the days it replaced slide rules as a portable calculator, and even today it remains on of the fastest and easiest pocket calulator to use by an engineer.
The larger beasts such as the TI-89 are fine for heavy lifting and complex transforms, but this variant of the TI-30 family is an superb buy for only a few dollars, and when the solar cell keep the power topped off so you don;t have to worry about batteries.
This, and a TI-89 should both be kept on your desk, or in your briefcase. One for the heavy lifting, ad the TI-30 for the lighter duty number crunching.
nice calculator.......2007-05-14
good stuff! buy one! has all the keys and functions you need!
Does what it's supposed to. Nothing more........2007-05-12
This calculator is a very basic scientific calculator. I recommend getting it if your school has a rule against graphing calculators and/or you are a cheap person who doesn't want to buy TI82 or higher or equivalent. I've never regretted buying this to replace the first one I bought for 5 dollars earlier that broke from old age.(I guess you can't expect a lot for 5 dollars postage)

Value servic e.......2007-08-10
Excellent product, very good price, reasonable delivery charge and fast delivery. Ease of ordering.
Thank you Amazon, may you live long.
got it for PE exam, now I use it every day.......2007-06-28
This was one of the few calculators on the list for the PE exam. It was also the cheapest (I think). I bought it, and started practicing with it at work so I'd be comfortable with it at the exam. It turns out that I love the data entry format. I used HP's RPN for a LONG time and thought it would be difficult to switch, but this makes even more sense because you enter the problem EXACTLY how you would write it on the paper (i.e. square root sign comes BEFORE the number)! I don't even use my trusty old HP now unless I accidentally leave this one at home. I am even thinking about getting a 2nd one so I can have 1 at work and 1 at home to study with (and I've heard that sometimes calculators walk away during lunch hour at PE exams, so it might be good to have a 2nd hiding in my bag).
The only flaws I've found so far are the instruction manual, quick auto power-off and the plastic cover. The manual does not go into enough detail but there are several references available online so, not a huge deal for me. When I get close to the exam, I'll probably print out my favorite and take it with me. The quick power-off (after about 6 minutes) can be frustrating, but I haven't really had a huge problem with it.
The plastic cover is annoying because it snaps on and off instead of slides. I don't know why this bothers me, it just does. Also, it would have been nice if the cover was flat. Instead, it is slightly rounded with "feet" to stabilize it. The feet work great as long as the entire calculator is sitting on a flat surface but if one corner is off, the whole calculator rocks back and forth every time you hit a button. Also, with the cover snapped onto the back, it is kind of uncomfortable to hold in one hand and enter data. With the cover off it is better, but I'm worried I'll loose the cover.
I am definately happy that I purchased this calculator instead of the more expensive HP that was on the PE approved list.
Wow!.......2007-06-07
This little thing is really a gem! I'm shocked at how much math a $20 calculator can do. Really helped me get through the FE as this thing solves quadratic & cubic equations, and even does numeric integration and differentiation! A very well designed tool.
Best calculator I've owned.......2007-05-30
Does everything I need it to do for engineering classes without all the extra frills and distracting buttons people never use.
Excellent calculator for the price........2007-05-15
I bought the HP 33S last year for the sole purpose of taking the PE. I have been using HP calculators and the RPN logic for more than 20 years and felt very compfortable with it; however, the 33S was a dissapointment to me, for one reason, good luck trying to see the decimal point, so 33.457 looks like 33457, that one little thing turned me off from using the 33S, so I went and purchased the casio fx-115MS, what a calculator!!! So many functions, and ease of use, the two lines are a beauty, and the numbers are huge, and don't forget the decimal point, I can really see it. I think I'll buy another one as back up. Now, if only the Casio can take the PE test for me!

Great for Engineers.......2007-09-21
I just got my HP33s a few days ago, and I am not disappointed in any way. It is very powerful with lots of features and options, extremely light, and very comfortable both handheld and while using it on my desk. I did not have any problems reading the display, and the keys, although arranged differently from the old HP45, are comfortable, not sticky, and have a great tactile feedback. It is easy to write programs and macros, and all the features I frequently use in my everyday engineering work are directly available on the keyboard. It can also work in binary, octal, and hexadecimal (I wish I had one while I was in college). It does not come with a charger or wall plug, or a computer link, but it uses two parallel batteries, so you can replace them one at a time and never lose whatever is in the calculator memory. I have not tried the algebraic mode yet but I find this to be a great feature for somebody who is not used to RPN yet. It includes all the trig, log and stats functions and also includes many conversions and 40 constants so you do not have to remember Avogadro's number or the speed of light. Yesterday I challenged my son, who is in engineering school, to solve a few vector analysis problems, he with his TI83 and I used my new HP33s; I beat him every time. Overall I think it is a great buy.
Solid Pocket Calculator with Good Balance Between Power and Portability........2007-09-05
I purchased this calculator for my upcoming Fundamentals of Engineering exam, and although it is the priciest of the calculators allowed on the exam, it's worth every penny. The calculator is programmable with equations, can perform integrations, and can solve equations via HP's Solve application. The only thing I was disappointed with was the programming structure. The calculator has ample memory to store programs, but it only allows programs to be called by labels which are limited to one letter from the alphabet. Still though, the ability to solve equations in a program and integrate within a program more than make up for this lack in programmability. As a plus, this calculator allows the use of both algebraic entry or Reverse Polish Notation entry. Anyone who works with difficult equations with multiple nesting of operators will immediately appreciate RPN once they learn how to use it. It saves me a good twenty keystrokes every time I solve a problem.
One of HP's lesser efforts.......2007-09-03
I am an engineer, and have been using HP RPN calculators daily for over 32 years, first in college, then in my professional practice. I have often said that the day I can no longer obtain one will be the day I will have to retire. I'd almost rather go back to a slide rule than use an algebraic calculator. My most recent prior calculators (a 32SII and a 42S) were showing distinct signs of aging, so I was VERY pleased when the 33s came out.
That said, this is my least favorite but one of all the HP calculators I have ever owned. (The least favorite is the 49gII graphic calculator, which doesn't even implement HP's signature RPN stack correctly.) The display of the 33s is of poor quality, and hard to read, the keys are sticky and don't always "register" my keystrokes, and the key placement design is very bad. One of my pet peeves about HP has been that with every generation of calculator they redesign the keyboard layout. The five HP calculators I have in front of me as I write (one of them an emulation running on my Palm T/X) have four different positions of the all-important "ENTER" key. On the 33s, the "ENTER" key is very small, and next to the decimal point, with the result that I frequently hit "ENTER" when I mean to get the decimal. This, plus the sticky keys, causes me to make more mistakes in calculations than usual. (Fortunately, after 32 years, I usually know when I've made a mistake. Sometimes I think the whole point of calculation is just to verify the answer I already know to be correct.)
I should comment that I hardly ever use some of the advanced features. I've not even figured out how to program it. In the early days, I used to write a LOT of calculator programs (who remembers the magnetic cards on the HP67?). Nowadays, though, I have a computer.
The best calculator for NCEES exams.......2007-08-25
Like many buyers of the HP-33s, my purchase decision was forced by the NCEES calculator policy on the April 2005 FLS exam. As of 2007, NCEES still only allows 4 specific models of calculators:
1. Hewlett Packard - HP 33S
2. Casio - FX 115MS or FX 115MSPlus (may have SR designation)
3. Texas Instruments - TI 30X IIS
4. Texas Instruments - TI 36X SOLAR
There are several points of difference that separate the HP-33 from the other 3 allowed models: It is the only one that is programmable, and the only one that uses RPN (a must-have feature for most users that have ever worked with an RPN calculator). The HP-33 has 26 user memories, the next best model on the above list has only 5 memories. Many types of problems on the PE and LS exams may involve multi-stage solutions where the ability to store up to 26 intermediate numbers will save you from having to write them all out on paper. A typical example (from the LS exam) is State Plane to Geodetic Coordinate Conversion. This problem involves 4 separate, inter-related equations to be solved, which use 6 or 7 different table constants and a dozen or more intermediate variables. By the time you have worked through one of these problems, you will have generated values for at least 24 different constants and variables, and the HP-33s is the only calculator on the approved list that will let you store them all. For the FLS exam, I created programs to solve Horizontal Curves, Vertical Curves, Grade/Bearing/Distance Intersections, Areas of Irregular Polygons by Coordinates or by Traverse, and the above mentioned State Plane to Geodetic conversion. Having these programs on the calculator probably saved me at least 30 to 45 minutes of manual number crunching in the exam, and probably prevented many erroneous answers due to "fat-finger" mistakes that would have been made if the problems had been manually calculated. Bottom line is that the HP-33s is really the only calculator you should even consider for an NCEES exam.
That said, I next want to lay out some of the gripes I have with the HP-33s.
1. Battery life is poor. I personally dislike CR-2032 batteries; they don't last very long in power-hungry devices like programmable calculators, making them pretty expensive. The manufacturers like them because they allow the device to be a lot thinner than it would be if powered with "AA" or "AAA" cells like the HP-50. My HP-33 goes through a set of batteries about every 6~9 months. The new HP-35 also uses CR-2032, and HP's web site states battery life on that model is also only about 9 months.
2. Memory is not "non-volatile". If you let the batteries die, all programs and data are lost and have to be keyed in again by hand, since the HP-33 has no way to back up it's memory to a PC, flash card, or other non-volatile storage. With 32K of memory, the HP-33 can hold many thousands of steps of program code: enough that it would take you a whole weekend or longer to key it all back in again if you actually had filled that whole 32K with programs.
3. The programming language, while relatively powerful for a sub-$100 calculator, has a few really annoying quirks. The worst is probably that there are only 26 "program labels" available ("A" through "Z"), and you have to use a label for the first line of any program "GOTO" or "EXECUTE" call. This is really bad news for any kind of program that involves a lot of conditional testing where you would branch to one or another subroutine depending on whether the test result is "yes" or "no". It would be far better if the language allowed for subroutine branching to a specific line number after a conditional test, so that you could save those precious few Labels for the first lines of the main programs. Not having line-number branching requires the programmer to write code that is a lot bulkier (and slower) than it could be, in the effort to conserve those 26 labels.
4. Readability of the display is really poor compared to most other calculators. As other reviewers have mentioned, the decimal point is TINY and far too easy to mistake for the comma in numbers with more than three digit places left of the decimal point. One can only hope that this annoyance has been fixed on the new HP-35. I do like the two line display, it is really nice for functions like Polar to Rectangular conversion. Once you have used any calculator with a two-line display, you won't want to go back to one that doesn't have this feature.
5. I don't like the slanted keyboard, which is unlike that of any past HP calculator. The fact that the "ENTER" key is the same size as all the other keys is really irritating, considering that HP has always used a much larger "ENTER" key on it's RPN models. People who have not previously owned HP calculators may not have an issue with this. On the plus side, the keyboard is at least pretty comprehensive and gives access to most of the commonly used commands without having to dig too deep into sub-menus.
6. Programs sometimes seize up, or go into an endless loop that you can't kill with the "C" key; this is especially noticeable in programs that make use of the equation solver. Fortunately, there is a button on the underside of the calculator to force a reboot if none of the regular keyboard commands will stop a runaway or seized-up program. You will need a sewing needle or pin to push this button, as it is accessed through a really tiny hole (~0.7mm) in the casing.
7. Durability (or lack thereof). My HP-33s suddenly died about 28 months after it was purchased, for no apparent reason. Others have reported similar premature deaths of this model, raising questions about the build quality. Many people own HP calculators that were manufactured 20+ years ago that still work. I myself have a 1981 HP-67 that still works except for the card reader (it seized up in 1988 and HP no longer had the parts to repair or replace it). The point being that HP has always had a good reputation for building calculators that could stand up to hard use; the HP-33 just doesn't seem live up to the old standard of quality and durability.
SUMMARY: The HP-33s is currently by far the best calculator choice for the NCEES Engineers and Land Surveyors exams. I would rate it 5 stars in that respect. And it is a pretty good calculator at it's price point. BUT, it has so many (relatively minor) annoyances and shortcomings that, if you are NOT buying a calculator specifically for an NCEES exam, you might be better off with the new HP-35, which is priced only a few dollars more than the 33 and has 800 memory registers (to the HP-33's 26). Then there's the HP-50G, which has light-years more capability than the HP-33, and is only $123 right here on Amazon.
RATING: Could have been 5 stars, but the questionable build quality and durability, short battery life, hard-to-read display, and lack of indirect addressing in the programming language force me to rate this calculator at only 4 stars.
NOTE: Taking a look at the specs for the new HP-35, I get the impression that it might have a lot in common with the HP-33s. It has about the same amount of RAM user memory, 30K, and uses the same CR-2032 batteries (a bad sign as far as I'm concerned). All I could find on-line at HP's web site was a basic spec sheet that doesn't go into any details.
The biggest problem with the HP-33 is probably the fact that you can't back up your programs, risking the loss of a lot of time to key everything back in if the batteries go dead. On the other hand, it is this very lack of connectivity to other devices that is the reason that the HP-33 is one of the four calculators that NCEES does allow in it's exams.
UPDATE: The HP-35s uses pretty much the same RPL programming language as the 33s, but it has been upgraded to allow branching to line numbers! YAYYY! Thanks HP for listening to customer feedback. The HP-35s is missing a couple of functions that have been on most other HP scientific calcs, most notably Polar/Rectangular Coordinate conversion, but this can be worked around with a small program. If the NCEES adds the HP-35s to the list of approved calculators, I would definitely recommend it above the 33s.
Decent Calculator.......2007-08-24
I am just getting used to it. I still have a couple of years before I take the P.E. exam (I hope that it is still allowed on it). Previously used HP 48GX. RPN input is the way to go. This calculator can do both RPN and algabraic input though. I like the size and weight as well.

Great!.......2007-09-22
HP has done well going back to what works. This is a vast improvement over the 33S with it's poor key layout and hard to read display. The 35S buttons have that classic "HP" feel, the layout is easy to navigate, and the display is nice and easy to read. As a practicing civil engineer, this calculator just plain works - just what I need without a lot of features that I would likely never use.
Great Calculator.......2007-09-09
I've been using HP calculators for almost 20 years and am very happy with this one.
The keyboard layout and feel are both absolutely perfect in my opinion. It retains the HP tactile click without having stiff keys with long travel, which is my only problem with the new HP50g (otherwise awesome calculator). I have a big, nasty equation that I used to test my speed with my calculators. It took 30 sec. on my 33s, 25 sec. on my 50g, and 22 sec. on my 48G which I've been using for 10 years. The very first time I cranked it through my 35s, literally
<2 minutes after inserting the batteries, it only took 23 sec. This calculator is optimized for cranking through big hairy equations. To me, that's what an engineering calculator is for! I have Mathcad, C++, Matlab, and Mathematica for all the stuff that graphing calculators do, but that's another story...
Pure RPN does take a little getting used to if one is used to the graphing models' RPL, but the 35s implementation is correct. My previous calculator was a 48G, so I found the 4 level stack to be slightly irritating. Took an hour or two to completely get over that when I bought my 33s a while back.
I actually like the tiny batteries instead of AAA because this cuts down the weight of the calculator. AAA batteries in the 35s, which is a very elegant little calculator, would've been insane. Also, what's the alternative? Feeding AAA batteries, 3 or 4 at a time, to a graphing calculator once a month?
Unless it dies on me, I think I'll be very happy with this calculator for a long time.
Best Scientific Calculator Available Today.......2007-09-06
This is a very nice high-quality scientific calculator from HP. The overall design and capabilities are similar to the HP 32SII (equation solver, unit conversions, etc.), but with several enhancements.
Like many recent HP models, this calculator can work in either RPN or algebraic mode, but I use only RPN. The keyboard layout has been well thought out, with most functions being quickly available directly from the keyboard and a few lesser-used functions available through menus. The keyboard has a traditional HP layout and colors, and the keys have a nice positive feel. A very thorough and well-written printed manual is included.
A new feature with this model is that each level in the four-level stack may hold a real number, complex number, or 2- or 3-element vector. Complex numbers may be entered very simply using the "i" key (or "theta" key for polar form); vectors are entered using square brackets. This design makes it very easy to manipulate complex numbers and vectors.
The calculator includes 30 kB of memory, which is enough for over 20,000 program steps. There are 26 main memory registers (A-Z), six statistical registers, and 800 more memory registers available through indirect addressing. Another new feature of this model is TWO indirect registers, (I) and (J).
A few cons: With previous HP calculators, there was a shortcut for entering exact powers of 10: for example, 10,000 could be entered as "E 4". For some reason HP has dropped that feature on the 35S, so you now have to enter "1 E 4". Not a major drawback, but kind of annoying since I used that shortcut a lot on previous models. Another nit is that the function to convert HMS to decimal hours is labeled HMS-> instead of ->H, which I haven't gotten used to yet.
Overall, the HP 35S is a very well-designed calculator, and I would not hesitate to recommend it as the best general-purpose scientific calculator available today. In fact, I bought three (for home, work, and school).
HP Calculator Comeback.......2007-09-04
The new HP 35S is a big improvement over the HP 33S and works well as an inexpensive RPN scientific calculator. Good keyboard feel and clear display.
Great retro styled calculator, you'll love it, and it may replace your desire for a 15C or 32S.......2007-09-03
This attractive calculator has the right shape and size to fit in the hand comfortably. It is smaller in height than the HP 48G but is approximatley the same width. The HP 48G Calculator Dimensions are 7.1 x 3.2 x 1.2 inches while the HP 35s Dimension are 6.2 x 3.2 x 0.7 inches. The calculator is slightly wider in the middle than at the top and bottom by about i~ 3/32" , but I can't feel this difference in my hand.
As far as the famous HP tactical key feel, I have the HP 48G+, the 49G+ , the 50G, and the 35s keyboard feels better than any of these. The feel is much, much better than my ti-85, ti-89, Casio FX-2.0 Plus and FX-115ES calculators.
The calculator uses standard RPN entry like the HP scientific calculators of the past. However, RPN isn't exactly the same as the RPL which is used by the HP graphing calculators i.e. 48G, 49G, and also the HP 28s scientific calculator. Here's an example of RPN, enter a number on the HP 35s, it moves one copy up the stack and it keeps a copy on the entry line. However, as soon as you begin to punch in a new number, the copy on the entry line disappears. So 3 ENTER 2 + does equal 5. The HP 48G through 50G uses RPL, and I can hit enter after every number, and then decide, with several numbers in the stack, what I want to do with them, multiple, divide, etc. Beware of comments regarding this subject, and I recommend you go to oither sites to find out more about this subject and I have included some references at the bottom of this review.
The calculator does take two CR-2032 button batteries but button batteries were used in the Hp 11C, 15C, and 32S calculators. The CR-2032s are common button batteries and are available at Wal-Mart in two packs, and Battery Bob offers them is 10 packs.
The display is clear and the digits are much bigger than on the HP 50G, and I can see easily see the commas and periods when they are there.
A real nice extra is a real printed manual for the calculator (5-3/8" x 8-1/2"x5/8" thick. Wow, not even ti gives you a real manual today. The manual is well written with good examples, and is much better than the HP 49G+ manual.
There seems to be some sort of confusion whether it does Rectangular to polar conversions, yes the calculator does these conversions (see 4-10 and 9-5 of the user's guide).
Build quality is very good, and no it is not the same as the early HP calculator that you could drive your car over. However, this calculator achieves the right balance between price, quality, good looks, and performance. That's a better mix than the earlier HP calculators achieved, I know, I bought my first high end HP RPN calculator in 2004 because it was cheaper than the high end TI calculator. Previously, Hp calculators always commanded a premium cost which might have been a contributing factor as to why HPs weren't more popular. I used Ti calculators during most of my engineering career because of the HP cost difference and the fear of RPN. I switched brands when the chinese TI-89 Titanium calculator came out. The Ti-89 Titanic had the smiley face keyboard layout, similar to the chevron appearance of the HP 33, and the looks of a bloated electronic gaming toy. That was enough, so I look at the HP 49G+ and switched. The 49G+ cost was less than the TI 89 Titanic, and I discovered RPN wasn't the backswords beast I thought it was going to be. The rest is history and I found out, twenty five years too late, that I like RPN calculators.
My advise is to compared this calculator to any other scientific calculator on the market today and you will find that this calculator reeks of quality, has the keyboard with the double wide "ENTER" key in the right location that RPN fans asked for, looks great, is programmable, comes with a real printed instruction manual, and includes a good, semi-hard, attractive case to protect the calculator. In fact, it is fair to say, nothing on the scientific calculator market comes close to this calculator. This calculator is absolute bargain and it is a great choice for anyone considering an RPN scientific calculator. If you're an engineering student and haven't used an RPN calculator, try this one or the HP 50G, don't wait like I did.
Bottom line, if you wanted an HP 11C, HP 15C, or an HP 32S but missed out or you simply refuse to pay $250. or more on eBay for it, then get this calculator. You won't be disappointed. In fact, I might get a couple more since it has been awhile since HP calculators were this nice. Who knows, maybe in ten years it will be worth $250. on eBay.
Well done HP.... Thanks for this calculator.
P.S.
For those who want more than a two line stack display, and need more pixels in the display, have to have a calculator that uses AAA batteries instead of button batteries, and feel the need to press enter after every number, then HP has a calculator to meet your needs. It is the HP 50G, and I highly recommend this calculator as well.

Great Calculator - Teeny Weeny Manual.......2007-08-30
Being relatively new to scientific calculators the instruction manual is quite important..... well guess what, despite the warnings from others that this manual is almost unreadable I took a chance and purchased this calculator and lo and behold it's true, couldn't read the thing. Whipping out the magnifier and doing my best goober-impression with a blanket sized manual, I managed to read some before realizing how ridiculous this was. Finding the manual and appendix on-line I proceeded to try and print it but it's the same thing, same size. Between the OS X printer driver, Adobe Reader print selections (all a tangled mess)and the small size after two hours of trying to print a larger "typed manual" using duplex printing, much wasted ink and paper, I gave up and decided to returned it. The state of printing a simple B&W PDF manual in 2007 is deplorable, why can't they get something fundamental like this right. If you are counting on the "manual" to help, forget it, unraveling this huge single sheet of paper in class is a joke, if you know 'calculators' by all means, have at it.
8th Grade Daughter gives it two thumbs up.......2007-08-24
After reading the Amazon online review of the Casio FX-115ES, I decided to give it a try for my 13-year-old daughter who just entered the 8th grade. She is taking Alegbra 1 honors. I was a little hesitant since TI seems to be the dominant calculator at her school. She came home from school and was amazed that the calculator would simplify fractions in natural language. For example, she entered 2 divided by 22 and the calculator gave her the answer of 1/11. Of course, you click one key and it will give you the decimal equivalent. So far, I'm very happy with the purchase. I did purchase it locally at target for $18.99.
Amazing technology for the price.......2007-08-09
This is a pretty nice calculator, and Casio was able to put an amazing amount of gadgetry in it for below $20.
There are some little things that could be problematic: 1) The manual is printed on two poster-sized folded sheets of paper. Very small print, too. A bound booklet would be much nicer for the amount of information that needs to be covered.
2) It does too much for a school calculator. Some of the pretty-print/textbook features I consider disadvantageous for math understanding.
3) The algebraic/textbook entry becomes cumbersome for doing long repeated calculations -- also, there's no way to store an expression/formula/equation for use after (auto) power-off.
Excellent value - too bad it's not allowed in the PE exam now.......2007-07-30
I bought two of these calculators for the October 2006 PE exam, which I passed. I was very impressed with the capabilities of this inexpensive calculator - it did everything I would want for the exam, except perhaps being able to store pre-programmed equations, like the HP-33s. I had been using a TI 36X solar, and the added functions and display size of the Casio shaved quite a bit of time off my computations. I use it daily at work now. (Though I have already ordered the new HP 35s - I just couldn't resist! Any engineer who went through school using one knows that an HP RPN calculator is a "real" calculator!)
Warning - this calculator is no longer allowed in the PE exams by NCEES. I have no idea why. But, the similar 115"MS" model is still allowed, and is presumably the same calculator as the ES.
Good Value!.......2007-06-23
My wife teaches Middle School and purchased this for pre-Algebra after researching it on the web. Worked out perfect for her, and she considered it an excellent value for the money, and has had no problems with it. Easy to use. Instructions were easy to understand and useful.

I never got it!.......2007-05-12
I recieved a different item than I ordered, and in exchange for not complaining to Amazon, I was given my money back, except for shipping. I, instead, ended up with a TI-34, but NOT a TI-34II. The difference is quite a bit. The TI-34 is a horrible old calculator that reminded me of things they gave me in 3rd grade, and it broke soon after. The TI-84II was something I've wanted for a long time and have seen in action, and it is very good, so I do give it as good as review as I can without trying it out. I also want to let people know that it doesn't Graph so it's only useful for people who are too cheap for a graphing one or who go to a school that doens't allow graphing (or maybe someone out there prefers non-graphing for some reason).
Durable, Efficient, Simple.......2007-02-04
This is one of the best, well only, calculators I've ever used.
I bought this back when I was in 6th grade and I've been using it since (Now I am a sophomore in college, 7 years, give or take a year). Lower version of this calculator such as TI-30s have too little features or obscure and those TI-8* giants have so many features that if you want to add you need to press 10 buttons (exaggerating of course, but you get the idea). I've looked at my friend who have owned TI-30s and the "giants" they seem to be contempt with it but the giants seemed bombastic to me.
Even in my advanced calculus class in High School, my teacher asked us to do the graphs without the use of a graphing calculator, its a little tedious but it helped me learn the concepts and I used TI-34 II for all the addition, subtraction, trig, and various other functions.
What I like about this calculator is the fact that it have a 2-line display, I can see my questions as well as my answer. I can also plug in a complex single variable equations in one single line and solve, unlike those 1-line display calculators where you can't see what you've put in and have to constantly keep going back.
I haven't realized the power of the STO-> (store) button until my freshman year in high school (wish I would have earlier), but it is one of the most powerful features that you can ever imaging. It will actually store up to 5 values of your calculations and keep it in the memory until you manually delete it (powering off does not erase the memory). I mostly use the ANS function if I want to use the previous answer, but if I wont be using the answer in the next equation, all I have to do is STO->. It saves me tons of time.
The only "flaw", if you even want to call it that, is the fact that it does not show the numbers in scientific notation which are below 10 digits. SOMETIMES, its annoying, but its nothing you cant handle, eh mate?
Another issue, not a big deal at all but thought thought you should know, is the fact that in the beginning it might be tricky to put the lid back on the calculator, you think I am bluffing eh? See it for yourself when you buy it. The trick to putting it back on is to keep the calculator 45 degree angle in reference to the cover plate and gradually decrease the angle as the calculator slides in the "groove" of the cover plate. You'll see what I mean, hard to describe in words. Or just do what I do, just put one side of the calculator on one side of the cover plate "groove" and press the other end in until you hear a CLICK sound, the plastic is flexible so dont be afraid of breaking it :).
Durability wise, I've dropped this calculator at least 500 times, literally, over the course of 7 years and not once has it broken, screen faded, pixels missing, or anything of that sorts. Sure, there are a few scratches, but other than that it works just as well as when it was new. Just to let you know, my friend bought a TI-30 and he dropped it after 5 months of using it, not I dont know if it because of the way it fell or what but, he dropped it and broke the screen and he could only see it partially, of course, that was no use. I recommended TI-34 II then but he went with CASIO because it could solve derivatives :|, he is so lazy, LOL.
Anyways, buy this calculator and you wont be disappointed :).
Great for young students.......2007-01-04
I purchased this for my twelve year old son in seventh grade. I was going to buy the top line model . But after talking with his math teacher this is the one to get ! Does every thing he needs for middle school. I Will purchase the TI 9* Plus Silver when he enters High School ! For now this meets all of his school needs and if lost , or stolen, I am not out of a chunk of money !
Perfect for middle school level math.......2006-04-18
I have the original TI34 calculator and bought it back in the 6th grade for Pre-Algebra. I'm now a college sophomore and still use it occasionally. This calculator was perfect for Pre-Algebra, Algebra, and Geometry and I couldn't have imagined using any other calculator. There was no need for anything more advanced (such as a graphing calculator) in those classes. It is very simple to use and doesn't have too many buttons. In fact, I've never even used half of the buttons that are on it. It is very durable as it has lasted me 9 years of dropping it and spilling drinks on it. It is a must have for any middle school math student.
Funky functions & sticky buttons.......2006-01-02
I was looking for a calculator that featured fairly complex function capabilites, but wasn't too bulky or pricey. Having had a good experience with Texas Instruments' TI-34 model several years back, I decided to give the sequel a shot. Aside from having the complex function calculating capabilities I was looking for, the TI-34-II's main attraction is the ability to backtrack through previous calculations (up to seventy-some-odd calculations back). This is a most welcome feature for someone who's never really figured out the memory storage/recall thingy. It's also a great way to check and see if I entered a previous calculation correctly if I come up with a weird or undesirable result. But not only can I scroll up and down through previous entries, I can also scroll right and left to check out off-screen portions of calculations.
On a bit of a downside, it can be a bit of a bear to figure out how to work the TI-34-II's more complex functions, even with the help of the instruction sheet. I hadda do quite a bit of semi-random button-pushing to do sigma-sums and factorials properly. Fortunately, I managed to get the hang of things with a bit of practice. Also, a few of the buttons can be a bit stubborn at times, where a light or medium-strength push-down isn't adequate to get the number or function to register on the display screen.
Bottom line: If you can figure out the more complex functions and the occasional "sticky" button, The TI-34-II calculator is a pretty good number-cruncher to keep handy.

calculator.......2007-09-20
I would love to write a review but as of right now I have not yet received this product.
Better than the TI .......2007-06-24
I am a math teacher at a new private Bronx high school, and compared the TI-83 with the Casio in numerous regards before deciding which one our school would use. Hands down, the Casio wins, and it is cheaper as well. Note - I do not work for Casio or TI.
A) The calculator is more user friendly. The options are menu driven in a more intuitive way. What took me a minute or two to locate and figure out out the TI, took less than half the time on the Casio. Don't trust me- see for yourself.
B) The Casio is slightly faster than the TI
C)Features: The casio adds a dynamic graphing system (lets you change a coefficient and watch the graph change), which is very useful when teaching. I also like the EQUA feature, which lets my students calculate 2/3 equations, 2/3 unknowns, and solve quadratic or polynomial equations. Maybe the TI does this too, but I couln't figure it out.
D) The color thing I suppose is nice, but I use the CFX-9750, which is black and white and cheaper.
The only downside is that most colleges use the TI's, unfortunately. I liken it to most places using Microsoft when there are better alternatives out there (monopoly power). Anyway, a student who uses the Casio can do anything the TI-83 can do.
I'm a big fan, and my students seem to like it.
Like a charm.......2006-11-11
Works like a charm. Much easier to use than Texas. Comes with good manual.
Great sometimes, others..........2005-10-19
The Casio fx-9750G PLUS is a great calculator for some things, terrible for others. Doing polynomial equations is simple, expecially when compared to a Texas Instruments' version. On the other hand, I have yet to figure out how to do a standard deviation. Keep in mind that if you're in high school, your course is almost definitely using a Texas - I can't tell you how many nights I've spent poring over the manual figuring out how to do the simplest of operations, while those with Texas Instruments know how to do it in a matter of minutes. If you're using it outside a formal math course in a situation that doesn't require too many complicated operations, it's a great calculator - I highly recommend. But if you're Pre-Calc or up, do yourself a favor and go grab a Texas.
Amazon is out of these calculators.......2005-06-15
This msg is posted on the 14 of June, 2005. Folks don't order this calculator if you need anytime before August 2005. I placed an order in end May, I am still waiting for the package. Late yesterday when I viewed my current orders, I noticed that the date when I am expected to receive this will be 5th of August 2005. Amazon still shows that the product will be shipped in 24 hours on its website.

Amazon.com Product Description
Once you get to a certain level of math classes, a regular old calculator just isn't good enough anymore--you need a high-functioning calculator that can perform algebraic, trigonometric, and statistical problems in addition to general mathematical tasks. The Texas Instruments TI-30XA scientific calculator can do this for you. It is extremely handy when it comes to figuring tricky fractions. It can add, subtract, multiply, and divide fractions when entered in a traditional numerator/denominator format. This calculator can also do a variety of conversions, from fractions to decimals, degrees to radians to grads, DMS to decimal to degrees, and polar to rectangular. The display screen holds up to 10 digits.
For high school or college students tackling advanced math, this is a great tool (and a thoughtful back-to-school gift), and with more professors allowing the use of calculators during classes and exams, it's a necessary one. Easy to use and easy to slip into a backpack, the TI-30XA will soon become indispensable for both the serious and the striving math student. --Dana Van Nest

1st one faulty, 2nd one ok.......2007-09-04
The original calculator I received became faulty within 1 week of use. CambridgeWorld sent me a new one to replace it in 2 weeks.
Horrible.......2006-11-29
i cannot use it its too confusing. im used to the casio calculators. not recommended.
great calculator.......2005-12-13
For the price, it is hard to beat this calculator. I've had this model for years and it is still going strong, with no problems or even a change of battery. Numbers are easy to read and the buttons are fairly large, with second functions labeled clearly. Lots of functions, and it is easy to use for stats. I also like the fact that it has an OFF button, which many models don't have. If you need a graphing calculator, of course this will not do, but for everyday use this model is a durable workhorse that I highly recommend.
A dissenting opinion on a terrible calculator.......2005-06-23
I bought two of these calculators and neither performs well - the buttons are terribly sensitive to the point that we often accidently enter the wrong numbers, so we have to pay extra attention. Further, my calculator is currently displaying entirely different numbers than I am putting in - perhaps the battery is dying, but I have no idea how long it may have been doing this. I will definitely be looking for a different calculator next time around.
Great simple calculator!.......2005-02-25
I have had this calc for roughly 7 years and i'm on my 3rd set of batteries. I mostly use my ti-83+ but whenever I need something quick or I can't use a graphing calc, I grab my trusty TI-30Xa! I love this calc!
