Summary: First off, production of this calculator ceased in what, 2001? I only mention that because I find it silly that this calculator is still selling for near $100. I purchased mine off Amazon years ago for $40. With that, do not let the age of this calculator turn you off, I guarantee the FX 2.0 is still way more calculator than you will more than likely ever need and if you do need more calculator chances are you will have moved on to Mathematica, Fortran, Matlab, or...
Summary: It's a good product overall for maths explanations, as also for algebra calculations. I've seen some things about the short-lifepan memory, but as i know casio solved that issue and 100000 write cycles it's very long enought. It can be added language apps, as well other apps and also developing in assembler your own apps. A great machine for professors, explainers and development engineers.
Summary: I have owned 4 Casio graphing calculators (including this AFX 2.0 and the AFX 2.0+) and a TI 89 Titanium. I've also used the HP 50, the TI 83/84 calculators. The Casio AFX 2.0 is one of the best calculators I have ever had or used. Compared to the 83/84 series it is, in my opinion, superior. While other students struggled to figure out how to use their TI 83/84, I was getting results.
Summary: Students can study how to solve algebra problems as ALGEBRA FX 2.0 PLUS shows each step to arrive at the final solution, in a similar way as a teacher does it in class. For students in any field, but especially math and sciences, Casio's FX 2.0 algebra graphing calculator is a problem-solving tool with features for storing, graphing, and analysis using the computer algebra systems, programming, statistical functions, and many other features.
Summary: I just purchased one of these about a week-and-a-half, two weeks ago and was disturbed to see that Wikipedia says these calculators quit working after a couple of years because the flash memory gives out: [...] Soooo.....I went out and purchased a TI-89 Titanium which also has CAS embedded in it, in case the Casio gives up the ghost sooner than expected.
