Exploring the Commutative Property of Addition and Multiplication

The video tutorial introduces the commutative property using a subway analogy. It explains that addition and multiplication are commutative, meaning the order of numbers does not affect the result. Examples are provided to illustrate this. In contrast, subtraction and division are shown to be non-commutative, as reversing the order of numbers changes the outcome.

Why does the commutative property not hold for subtraction?

• Because a - b is always equal to b - a

• Because a - b is not always equal to b - a
