Summary: In high school I had to purchase a TI-84 calculator as a requirement for class. Surprisingly, now that I am in college, I no longer can use a TI-84 or any "advanced calculator" model. That is why I purchased this calculator and it can do more than enough. I have used this calculator for calculus, as well as in business statistics, micro and macro economics, and accounting. Excellent model for the price.
Good basic 4 function Calc with trig functions. Did not use the statistical mode. Some what confusing instructions.

Summary: The calculator works well but has issues with colors used to differentiate secondary and tertiary functions labeled above the keys. These functions are accessed using either the Shift key or the Alpha key. The shift functions are colored coded in brown and the Alpha functions are color coded in maroon. In house lighting, for example in a living room, I found it difficult to tell what color was used on the alternate functions.
Summary: The calculator is a little bit un usual, in that it has dedicated keys for standard Engineering multipliers, like mega, giga, micro and milli. This in itself is no big deal, but I find that having these keys does save on keystrokes. Nice calculator.
