Understanding the Additive Inverse

The video tutorial explains the concept of additive inverse by combining opposite quantities. It begins with a review of absolute value, illustrating how numbers are measured from zero on a number line. The tutorial uses practical examples, such as earning and spending money, and walking forward and backward, to demonstrate how opposite numbers combine to result in zero. The key takeaway is understanding that two numbers that add up to zero are called an additive inverse.
