1) The best graphing calculator for Algebra I through Calculus.

2)The easiest way to play games in school. Download specially made games for your TI-83 off the net or from another TI-83 and tell your teacher you're doing math homework when you're really PWNING your friend at space invaders

A now outdated but still useful graphing calculator. Cannot be purchased anymore, replaced with ti-83+. Commonly used to play games in class or cheat on tests by typing in your notes (you know you did). Less powerful than ti-89 but quite perfect for High School use.
So I typed up my notes on my ti-83 last night. Want a copy?

A device created by Texas Instruments primarily as a productivity sink for math students. Has long since been replaced by models capable of creating even more distraction (like the TI-84 Plus).
It is true that I would never have gotten through college calculus without my TI-83, but seriously -- what did my professor think I was doing with it out in the middle of friggin' July with all the other summer school tards?
