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

5.0 out of 5 stars another impressed engineer, January 23, 2005

By	Voltron the Engineer (Pittsburgh, PA) - See all my reviews

This thing is a fully functional engineering grade calculator. I purchased this calculator a year ago for taking the Professional Engineering exam (The TI-89 was banned last year) and I figured that I better get use to using it if I were to use it on the test. It was simple to use. It was quick, it was powerful. The linear equation solver was faster to use than the one of the 89 which really impressed me (great for solving electrical circuits).

Overall, I highly recommend this calculator.
It has now become my primary calculator at work.

4.0 out of 5 stars Powerful, Excellent Value, January 20, 2006

By	Nick Tropiano (Havertown, PA United States) - See all my reviews (REAL NAME)

This powerful non-graphing calculator has over 300 functions, a two line display, and you pretty much enter algebraic expressions as they're written (just be careful to use parenthesis and order of operations). An overlooked feature is its dual power mode. If there's enough room light it runs off solar power, preserving batteries. No worries of the juice going during your final. (I'll take this feature this over extraneous, additional, functions of that new Sharp calculator.) This calc has MORE than enough in terms of functions, power, and various equasion, complex number, and statistical modes. In terms of pure number crunching power, this calculator blows everything else away in its price range, except perhaps the latest Sharp. A co-worker who has a Master's in math took a look at this and told me it's all the calculator you need, all the way up through graduate school.

Just note that this is NOT a symbolic algebra calculator - that is, it will attempt to solve for (multiple) variables, as in X=2.453. However it won't expand, group, or simplify algebraic expressions. Don't expect to enter (a+b)^2 and get a^2+2AB+b^2 back, or vice versa. For that, you'll need the much pricier TI-89 or TI-92 Plus, which has a symbolic algebra mode.

However, if you want the most bang for your buck, go with this over the lower-end TI's (imo) and others. Much more power for the same money, and this is very nicely designed.

Documentation is spartan but it'll get you there. Just have a magnifying glass handy or download the PDF file from Casio's site. The upside of having a small fold-out user guide is that you can always have it near your calculator. I keep mine rubberbanded to the calculator's case, so it goes where my calculator goes. (Having a 260 page book would negate the calculator's portability, wouldn't it?)

Some nice math instructor of few reviews down put together a great supplemental document for this calculator with some good examples. Highly recommended if you buy this calculator (and thank you).

Excellent product. Subtract a point for not having a more detailed downloadable user's guide with more examples on Casio's website. I can see not wanting to drive up the price by including a paperback book, but c'mon, Casio. It's 2006! We have the Internets and pdfs now!

5.0 out of 5 stars Great calculator - needs better user guide, June 1, 2005

By	Julius Nadas "Julius" (Chicago, IL USA) - See all my reviews

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
