 Son happy. Casio success in the past, too. October 9, 2009
J. Douglas (Michigan)
My son is completely satisfied with this for use in his first Algebra class. I bought this due to good experience with Casio calculators and the good price. I bought myself one in my 2nd year of college to use in Accounting - EL533 is the model, I think. I still use it. Purchased in 1985 and still works like a charm 24 years later. Can't beat that!
Good Quality September 12, 2009

easy to use
its got both solar and battery ways to operate
Its not a graphical calculator
good for sine cosine and tan use and similar usages
 misleading packaging May 31, 2009

The functionality of this calculator is 4.5 stars. The display is not as good. I purchased both the Casio fx-300ES and fx-300MS. If the display on the fx-300MS is a 10, the display on this calculator is about 8. The package of the fx-300ES does not allow you to press down on the clear plastic to see the display because the gap between the clear plastic and the face of the calculator is too deep. This design appears to be intentional because they don't want you to see what the display really looks like. There is also a plastic tape that is suppose to simulate what the displays looks like. This tape is misleading because the actual numbers are a somewhat light blue and not black like what the tapes displays shows.
Excellent May 22, 2009

The product is easy to use. Great for maths problems that contains fractions. I would recommend it to a friend.
Good but there's a bug... May 4, 2009

I chose this calculator after looking at 6-7 other candidates. I teach a Mathcounts class at a local middle school and this calculator has several key features. First and foremost is the 2 line, editable, display that shows me what a student keyed. That's crucial in helping me see where they made an error when they get a wrong answer. The 'editable' feature usually means that a few keystrokes are all that are needed to correct an error rather than re-keying the entire expression.
The second feature is the list of readily available functions. Mathcounts topics (mathcounts.org) cover a wide spectrum of mathematics far beyond what a typical middle school curriculum requires so the calculator had to have permutation, combination, and factorial functions. This calculator has them.
It handles fraction and radical notation nicely - it displays the square root of 12 as 2sqr(3) which helps the students check their conceptual understanding when we're rationalizing or simplifying radical expressions. Flipping between displaying 1/2 and .5 requires but a single keystroke. Flipping between mixed number and improper fractions requires only two keystrokes.
The solar panel has saved at least one student from having a completely dead calculator when he drained his battery. The panel ekes out just enough juice to give you a glimmering display which is better than nothing. A slightly larger solar panel would be nice.
Finally, the manual is available online so you don't have to try to read a multi-lingual manual printed in 6 point type on rice paper. Kudos to the project manager for posting the pdf. Much appreciated!
Unfortunately, there's a bug in the firmware which turned up in a calculator exercise. If you key in 75025 and ask for it to be represented to 4 significant digits in scientific notation, the calculator gives the correct result, 7.503e4. However if you arrive at 75025 by computing the 25th fibonacci number using f(25) = ((1+sqr(5))^25-(1-sqr(5))^25)/(2^25*sqr(5)), the calculator displays 7.502e4. Reset the display to show an integer result and it correctly shows 75025. Somehow, doing the calculation, as opposed to entering the number, confuses the display routine.
We work around the bug by rounding the result ourselves instead of relying on the calculator to do it but the bug somewhat reduces my confidence in the calculator's ability to correctly compute. Hopefully, the bug will be fixed by next school year when we buy another class their calculators. Were it not for the bug, I'd rate the calculator at 5 stars.
