Amazon.com Product Description
For math and science students at all levels and for any home or office needing to make algebraic computations from time to time, Casio has created the FX-260 solar scientific calculator. An indispensable tool for students from high school onward, in lab classes, and for exams, the FX-260 features a two-line display, complex number calculations, and an algebraic mode, which displays the example precisely as written. Always powered up, it's useful as a household/office calculator for calculating finances, converting cooking measurements, and anything else you can 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 equations. With the Casio FX-260, you can quickly clear errors with the backspace key. You can also call upon 144 built-in mathematics functions and several fraction functions for basic equations and for fun. Plus, call upon the FX-260's basic scientific, exponential, and trigonometric functions for everything you need to complete your assignments and lab work. Key in and program formulas to save for future uses.

The Casio FX-260 provides one independent and six constant memory keys. It has a pragmatic key layout, making this an easy-to-use basic scientific calculator offering all the functions you'll need in a solidly constructed unit. Also, solar power means never replacing batteries. --Barbara Price

Customer Reviews

Outstanding Casio quality for an excellent price
I have been using Casio electronics for over a decade now -- starting with first data bank and touch screen watches. The brand has never failed me, so I have chosen Casio FX-260 over TI and Sharp competitors again. The calculator is great for graduate classes in Computer Science and Finance for sure (this is what I am using it for), and I am certain it will be more than enough for Physics, Chemistry, and other sciences. Compact design, a high-contrast screen, rubber keys -- everything is just right. And if I want to do graphing, I will use Matlab. Highly recommend!

Good for tests. Lacks accuracy and convenient features
FX-260SOLAR is light, slim, and durable. This is also the official calculator for use on GED Math tests and is permitted for use on SAT and PSAT/NMSQT. It is solar-powered meaning you won't be stuck with a dead calculator in the middle of a test. The "mode" menu is printed beneath the screen so that you don't need the user's guide again. (Trust me. This is a BIG plus!) It also handles fraction calculation, converts degrees/minutes/seconds both ways, and computes mean and standard deviation.

However, it lacks the HEX-OCT-BIN conversion and complex number calculation features to make it an all-around technical calculator. Users also need to press SHIFT to use the "1/x" and "nCr" functions. In comparison, Casio FX-300MS offers a much more convenient layout and costs only $1 more with the sale going on now (April 2005).

On the numerical side, this model does not store enough digits to be a good financial calculator. For example, this model evaluates 200000 (1 + 0.06/360)^(360*30) to about 1209747.95. A more accurate answer should be about 1209748.04. TI got it; Casio did't. Although the difference is so small that it often doesn't matter in highschool problems, it looks bad on presentation.

Great priced scientific calculator
I recently bought one of these scientific calculators. This calculator is not only compact but it is also inexpensive. And since it is solar powered I never have to worry about the batteries running down if I leave it on. This is a great calculator to buy if you don't want to spend a lot but want to get a lot from it.
