My first scientific calculator was a Sharp. Then I spent many moons in the land of TI. I'm so fond of the TI-84+ I had firmly decided I was a TI-gal. Then, I tried to buy some for my classroom a night or two before the start of the school year and the store was out of TIs. They had this lovely calculator. I'm embarrassed to admit just how long I stayed in front of that display debating over whether I was willing to commit to an unknown brand, especially when I didn't care for the Casios I had seen before. Finally, desperate to have a few on hand for my students, I purchased them.

It didn't take long for my students to find all the neat features. I originally chose them for the permutation/combination features and was curious about how useful stacked fractions would be for high school students. WOW.

My only complaint (until recently) was that they are so fabulous, five of mine walked off. This was bad news...until...I discovered the next level up which includes imaginary/complex numbers. So for next year...I'm going to upgrade my stash and guard them more fiercely.

I only put four stars because I soooo want those complex numbers now and all the other features I'm thinking I can get. I still prefer a TI-84, but our students are not allowed to use graphing calculators on their end-of-course test so I want them to get comfortable with a calculator that will serve them well. I was wishing I could put 4.9 stars (or 49/10 stars as my calculator would say). This is really a wonderful little device.

The fx-300ES comes very close to 'ideal' for a high schooler, with support with many features such as regression analysis that are normally found on graphing calculators.

The feature that stands out for a calculator in this price range is what Casio calls 'natural textbook display': you actually see the fraction lines, the radical signs and the exponents just the way they appear in textbooks. In addition, there's an easy menu facility, multiple replay.

Of course this is a solar calculator so there's no need to worry about replacing batteries and, to top it off, it comes with an excellent, protective removal plastic cover.

Now, for features, this is what you get, besides the basic operations - might have missed one or 2:

- fractional calculations (can switch between fractional and decimal)
- sexagesimal functions
- trig and inverse trig functions
- permutations / combinations
- coordinate conversion
- logarithms and exponents
- power functions
- factorials
- calculations with radical and Pi symbols displays and simplifying radicals
- tables
- standard deviation
- regression

This is our second fx-300ES because the one we bought a couple of years ago stopped working unless exposed to very bright light (solar deficiency). We ordered a second because our 10th grader son told us that he had to had a replacement and he wanted this specific model.

For a scientific (not financial or graphing) calculator this is tops so the the premature death of our initial fx-300ES forgiven, it's a 5-star.

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.

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!
