Product Description
Amazon.com Product Description
For math and science students at all levels, and for any home or office that needs algebraic computations from time to time, Casio has created the FX-115W Plus two-line display scientific calculator. An indispensable tool for students from high school onward, in lab classes, and for exams, the FX-115W Plus features a two-line display, complex number calculations, and an algebraic mode that displays the example precisely as written. It's useful in the household or office for calculating finances, converting cooking measurements, and anything else you think of when you wish you had a calculator at hand.
The clear, readable, two-line display exhibits 10 digits in large numerals, showing the problem and answer together and permitting better tracking of your equation-solving process. You can also call upon 279 built-in mathematical functions, many complete with engineering symbols, for a variety of tasks, including calculations in base conversions, logical operations, and standard deviation and regression analysis. Plus, you can key in and program formulas to save for future use.
The FX-115W Plus provides one independent and six constant memory keys. It has a pragmatic key layout, making this an easy-to-use basic scientific calculator offering the functions you'll need in a solidly constructed unit. --Barbara Price

The Fx 115 MS is the most powerful non-graphing calculator I have used. It is ideal for non Math students who are required to take an intermediate college algebra class. Unfortunately the single sheet of instructions are insufficient for the type of student that would benefit the most from it. I have put up a web site for my intermediate algebra students that tries to explain to them how to take advantage of its many features: http://faculty.ccc.edu/jnadas/graduate/CASIO.fx115ms.HTM

I bought the 115es originally, and for some reason, NCEES disallowed it from the FS/FE exams, so i also got the 115ms. Note, NCEES appears to be allowing the es again; the approved Casio model has to be a FX-115 model, no designation as to it having to be the ms.
So the ms is very nice! Very clear, crisp display, intuitive keyboard, these things being better than the es. The ms is also full-featured, having solve & calc functions (very handy), ability to do derivatives, integrals, quad & cubic equations, solve simult equations of up to 3 unknowns, full statistics capability, etc. But the ms will basically be relegated to being my backup to the 115es, because the es does everything the ms does, and has unit conversions, scientific contants, matrix, table, and vector capability; in addition to being more user-friendly in toggling between the desired mode of operation or setup style.
I'm really not sure why Casio offers 2 such similar platforms, separated by a minimal price. . . i mean for the money, why wouldn't you get the 115es? Hopefully, NCEES will not exclude the es from its approved list again (totally don't know why they did in the first place). But comparing either casio model to the approved texas instruments models, or the HP models, the casios offer great value & practicality, without a huge learning curve.
If you're not remotely concerned w/ any of this NCEES speak (i don't blame you), buck up to the 115es. For a few $$ more than the ms, it provides a lot more features.

I have been a faithful user of the HP 48G since 1995. However I needed a calculator that is permitted on the EIT exam. Since I am comfortable with Reverse Polish Notation entry format, my first inclination was to look for a HP product that is approved for the exam. However after reading the reviews on-line and seeing the price of the HP33S, I decided to look for an alternative. The TI 30XIIs and the Casio fx-115MS were viable options at a better price. I bought both of the TI and the Casio for comparison.
Both calculators are about the same size, approximately 6"(T)X 3"(W)x1/2"(D). The feel of the buttons/keys on the TI was a bit dull when pressed. The Casio keys had slightly more engaged-feel when depressed. The engaged-button feel helps when I am keying numbers without looking at the screen to know whether the calculator took the string of digits and operators correctly. The color scheme employed for button labeling on the TI does not make the "2nd" functions stand out. This is made worse by the shadow cast by the tall buttons, which make the lettering for the "2nd" functions harder to read. The Casio uses fairly distinctive colors for lettering and function schemes. This makes it easier and faster to find the correct key.
I find that for engineering problems, Casio had more built in buttons. Thus I don't have to always use "shift" or "2nd" functions. I also liked the layout of the buttons on the Casio. I feel it is a bit easier to find the right keys, due to more logical key placement for certain functions. On the TI, I have to spend more time hunting down the button.
A few reviewers have noted that the Casio manual that comes with calculator to be mediocre. That is also my perception after reading through the manual. The TI came with a manual and a practice guide. The TI manual is more thorough and sequential in presenting the information. The TI practice guide presents some simple problems and show the keys that need to be pressed. This helps get the user to become familiar with the key layout and input sequence.
To overcome the mediocre Casio manual, I searched on the internet and found a tutorial on how to use the fx-115ms written by a math instructor for his or her students. The tutorial is fairly detailed and easy to follow.
Overall, both the TI 30XIIs and the Casio fx-115MS are very capable calculators. However I found the Casio to be more suitable for my needs. I would give this Casio product somewhere between 4.5 to 5 stars.
