Q: How can I clear the memory of all variables and lists?

A: Unlike a complete reset (see below) this is pretty safe to do, though be careful not to delete any lists or variables that you need to save. To clear all memory in a TI 83 or TI 83 Plus:

1. Press 2nd MEM (that is the second function of the + key)
2. Select 2
3. Select 1 (All)
4. Scroll through the list and delete anything that isn't important.
