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.

2) Double click vti.exe. The program should run.

3) Just like the real calculator, you need to press the On button at the bottom left hand corner before it starts to function. (I didn't realize that so it took me a while to get this thing to work. lol!)
