Just like the Virtual TI-83s that you use at school except for your computer. Why buy the real thing when you can run a simulation?

Note: Requires Winzip to unzip the program from its package.

Instructions:

1) Unzip from Virtual TI.zip package. After you unzip it should be in a folder called Virtual TI.
