MP4 Videos: Using TI 83/84

Divx will play mpeg4 files

It is a fact that the SAT allows you to use a calculator. Make sure you have mastered your calculator. IF possible get a TI 83 Plus or a TI 84  Plus calculator.

Make sure that you have a mp4 player. I use the DIVX Player. The DIVX player will install a plugin into your browser. My browser is Firefox.
