Summary: I was unable to find TI-83 at a cheaper price. I need it for college and as you know, college students can be financially challenged. This is perfect. Just what I needed at a very reasonable price.
Summary: The calculator does what it's supposed to do; compute unimaginably difficult equations for me. I was going to get that no matter where I purchased this calculator. The difference, though, is that his calculator is easily priced over $100 elsewhere, but I got it much cheaper here. Thanks!
Summary: WOW! Who put all of this information in such a small package. When I think of all the time that I spent in school, interpolating logrithmic numbers with an opportunity for errors at every step! My grandsons will never have to own a CRC book of tables nor my archaic slide rule that is stored away somewhere.
Summary: As a beginner to the graphing calculator I am amazed by the ease of function of the TI-83. If you are not advanced with the functions of a graphing calculator I recommend that you start with the TI-83 as I have found that others are confused with the functions of the TI-84.
