TI-83 Math Program
509 bytes (Ouch!)

This program is so simple if you needed to know how to work it....then that's
just really sad.Unfortunatily, Version 1 has only 2 things:

* Interest

    and

* Percent

That's about all I have to say and if there's a different way you solve 
Interest,just go in it and change it.There will be more in it in the 
future versions, so bear with me for now.

Enjoy!
