Demonstrate the Commutative Property of Addition with a number line

This video tutorial explains the commutative property of addition using a number line. It begins with an introduction to integers, including positive and negative whole numbers, and explains the concept of a number line. The tutorial then covers the basics of addition, highlighting common mistakes related to the commutative property, such as reordering addends without considering their signs. Through various examples, the video demonstrates how the commutative property works with positive, negative, and mixed-sign numbers, emphasizing the importance of keeping signs with their respective numbers. The lesson concludes by reinforcing that the order of addends does not affect the sum, as long as signs are correctly maintained.

What happens when you apply the commutative property to the addition of two negative numbers?
