This calculator has 2 lines of display. The first line will hold up to 88 digits, the second line displays the answer. This calculator is capable of doing some trigonometry functions, fractions, rectangular-polar conversions, probablility (combinations, statistics and notations. It can be difficulty to use if you do not keep the book. However inside the plastic cover there is a small cheat sheet with some of the more common functions and how to do them. The calculator is solar powered so you never need to worry about running out of battery power in the middle of a test. The plastic casing/cover is very durable. I have dropped this a number of times and have had no problems. This is a good calculator for your basic algebra and triginometry class.
