Summary
Counting fingers is one time-honored technique for adding and subtracting integers. But what happens when you run out of fingers? In this BrainPOP movie, Tim and Moby teach you how to handle the addition and subtraction of bigger numbers--not to mention what to do when some of those numbers happen to be negative! Discover how useful a number line can be when dealing with positive and negative integers. Explore how absolute values and additive inverses can help bring those integers together (or split them up, for that matter!). And learn how adding a negative number is the same as subtracting a positive one, and how subtracting a negative number is the same as adding a positive one!
