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

Una calculadora que ya no se encuentra en todos lados, de la mejores. La compré por la nostalgia por mis años de prepa. Sin embargo puedes encontrar más nuevas.

The calculator I received from this seller did not function at all. I understand it might have been just a fluke.

I bought this calculator for my personal use, not for using on tests in school. I like it because it has two line display, adjustable contrast, does fractions, and can be used for General Math, Pre-Algebra, Algebra I & II, Geometry, Trigonometry, Statistics, Calculus, Biology, Chemistry, Physics and Engineering. It is also permitted on tests for AP, Sat I & II, PSAT/NMSQT & ACT.When mine arrived, the package contained the calculator, snap on cover, two name labels, warranty card from Casio, and instruction manuals in English and Spanish. According to the Casio warranty card, this product has a one year warranty, from manufacturing defects. Overall, I'm satisfied with my purchase.

Once you’ve actually figured out how & when to use the different modes. This calculator is a life saver. Everything from converting fractions & simplifying mixed fractions becomes a breeze. I used this for my Algebra as well as my basic Electricity class & it’s hasn’t failed me yet. Extremely long life as well. My professor has had his for 7yrs without having to replace the battery!

I've been teaching engineering courses (thermodynamics, engineering economics, fluid mechanics, etc.) at the Bachelor of Science level for about 20 years, and this has been my calculator of choice for the last 15 years. It has all the math functions I need, and an easily readable display, which is essential when working through problems in front of a class. If the fx-115ES display was like the "115MS" display I'd probably use it, since it is a bit more capable in handling simple calculus functions.The fx-115MS never needs batteries, and is acceptable for taking the FE and PE professional exams. Why not become proficient in using a calculator like this before taking one of these exams? Graphing calculators - loved by Math Departments - are "overkill", and exhaust batteries in no-time. No "..my batteries died.." excuses in an exam with the fx-115MS.If you have a large problem, get on your PC and run Excel, MATLAB, or MathCAD to solve it. Otherwise, the fx-115MS should work just fine.

I have always liked Casio calculators for their value, durability, and ease of use. I found very few calculators out there that will convert between Decimal and Hex, Octal, and Binary, which is essential to my job as a computer programmer. It also has trig functions that I use every day, as well as DMS conversion, radians, and fractions, just to name a few. It has far more functions than I'll ever use.It has both battery and solar power. The screen is 2-line and easy to read. It uses the new method of input which I have yet to get used to (and I dislike tremendously, but then I'm Old!), so you hit Sin 45 =, not 45 Sin. At least you can see what you entered on the top line in the event you make a mistake. It's inexpensive and well worth the money.

It's a good calculator for engineers and scientists. The price is not too high for its functions. The two-line window is convinient, and the size of the alphanumeric characters is appropriate. Using both solar cell and dry batteris, it saves operating cost also. Touch bottons work very precisely and nicely.Overall it's a good scientific & engineering calculator for its price. Two shortcomings may be improved hopefully. First one is its automatic shut-off function. Hope the company gets rid of this function, or increase the shut-off time to 1 hour or so. If you are idling, the calculator automatically shuts off within 6 mins. This time is way to short for many many calculations. Sometimes we have to stop and recheck the problem statement or written equations. While you are rechecking, the calucaltor shuts off, and you never be able to resuscitate the equations you typed in before shut-off. Duh..Second, the case must be improved. This case (or plastic cover, if you will) is supposed to be put under the calculator, but the shape of the cover is round, and it wobbles when you punch the bottons.

This calculator was recommend for an AC Physics course I'm taking and it is a great deal.Two things that are particularly great about this calculator are that you can enter scientific notation prefixs (p for pico, n for nano, etc.) so you don't have to do the conversions in your head.Another highly useful aspect for electrical and engineering applications is the ease with which you can enter polar and rectangular coordinates. For most calculators I've owned they either lacked the feature entirely (it is rare to find polar and rectangular support in calculators at this price range) or were extremely clumsy to enter and use.It also appears to do differentiation and integration (a surpise for such an inexpensive calculator) but I haven't had need for those in my current courses so can't say how well it does them.
