 Good for the most part May 10, 2008

It does all you need it to. exponents, square roots, squares numbers, etc. It's very easy to use and the graph is also very easy to use. It's very hard to read exact numbers on the graph, probably due to the small size of the screen. If you want to graph a table, this feature doesn't exist with this calculator like it does with the more expensive TI-83.

The calculator itself is fine. Seems easy to use and comes with the instruction book so that is a plus. However, the hard case fits the back of the calculator very well but DOES NOT stay on the front where it is needed the most!!! I probably would NOT buy this particular calculator again because the hard case does not protect it. It's fine if you don't want to carry it or take it anywhere. As long as you only keep it at home on a desk or something then it is fine.

This calculator is very capable of computing complicated algebraic equations. A lot of my classmates have a TI 34-36 and were having problems calculating fractions, or converting from decimal to fraction and back again. This is very easy to use and just a few minutes reading the guide will get you very familiar with how to use it. The bracket feature seems to confuse the calculator, so just use the parenthesis as often as you can. I was very surprised at it's capabilities, especially since I only paid $18.00 for it.
