You need 4 AAA batteries for your calculator!

AAA batteries

Checking out a graphing calculator:

1. You are checking out a graphing calculator with a unique identification number. This is important because you cannot return just any graphing calculator! It has to be the same one that was originally checked out to you.

2. Your school provides your batteries for you! You can buy your own AAA alkaline batteries.

3. If you lose or break your calculator, you will be charged $100. If your calculator is stolen, you will be charged $100. Moral of this story -- don't lose or break your calculator, and make sure you keep it in a safe place!
