Properties of Operations in Mathematics

This video reviews the commutative and associative properties, which apply to addition and multiplication. The commutative property involves changing the order of terms, while the associative property involves changing the grouping of terms. Examples are provided for both properties, and the video concludes with a review and practice problems to reinforce understanding.

Which property allows you to change the order of numbers in addition or multiplication without changing the result?

• Associative Property

• Distributive Property

• Identity Property

• Commutative Property

What is the result of applying the commutative property to the expression 3 + 5?

• 5 + 3

• 3 * 5

• 5 * 3

• 3 - 5
