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!

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.

This little calculator is my favorite calculator of all time. It has been the only calculator I've needed for Algebra, Trigonometry, Calc I, II, and III, Discrete Mathematics, and Differential Equations. I believe I've gone through enough fundamental classes to say with confidence that this calculator has every function you will need.

Things I love about this calculator:

1) Durable
2) Light
3) Small, doesn't take up much room
4) Cheap
5) Works in fractions (won't reduce them to decimal values)
6) Has all the trig functions
7) Even has a pseudo-random number generator
8) Has all the scientific functions you could need
9) Its x^y function accepts fractions for y

The only thing I would add to this calculator would be a logarithm function that I could assign my own base to (log_y). It already has log_10 and log_e, but sometimes a log_2 is useful as well, for instance.

I think the size of this calculator is perfect. It's small and thin, but not too small. The screen is perfectly readable, and the buttons are the rubberized type that provide a nice tactile feel.

20 of 22 people found the following review helpful By James Q. Smith TOP 1000 REVIEWER on March 22, 2010
I bought this calculator as a general purpose tool, rather than for school. I've owned 4-5 Casios in my lifetime, 2 of which are nearly 30 years old and are classics, they are the older versions of this fx260. In 30 years, functionality, build quality, and the Casio ease of use are identical; it differs mostly in the older Casios were partially built of aluminum, and are far heavier than the fx260. My other 3 Casios were stolen. This new calculator was meant to travel and get abused.

I like this fx260 the best, for reasons others have mentioned. Further, the keys make a nice tactile click with depressions, screen is clearer, calculation speed is faster, the solar cells are more sensitive to lower light conditions, its light and sized to fit a shirt pocket with its case on, it feels good as a hand held.

Why get the fx260 instead of the other reputable Casio Casio FX-300MS Plus 229-Function Scientific Calculator which has almost 100 more functions for just an added $ 1-3 ? Ergonomics and required functions mostly: the 300MS is much bigger, it won't fit a shirt pocket, its heavier, and its keystrokes differently compared to a basic Casio. Many learning aids and high accuracy calculators are better as software on laptops with higher resolution graphing screens and libraries of functions. Handheld calculators are better focused in being portable, like a swiss-army knife tool for small jobs. If you don't need extra functions, unused but excess capacity makes it harder to lug what should be a go anywhere, easy to trot, calculator.

Earlier I possesed a Texas Instruments TI30XA Scientific Calculator but had to buy a new calculator since I lost my previous one. So I decided to try some other make and bought Casio FX-260. This calculator is much more user-friendly than Texas Instruments and is much cheaper too! I use this calculator for solving Calculus 2, Mechanics and General Chemistry related problems. They work great and sometimes I feel it was good that I lost my previous calculator.

The Casio fx Solar fraction calculator is used in teaching my math class of young , primarily Mexican mothers to prepare them for GED tests. Some calculators have been in use for years without failure. The solar feature is remarkable ,works in very dim light, and is inexpensive.
