Exploring Key Math Properties: Commutative, Associative, Distributive, and Identity

The video tutorial by Tiffany covers four main math properties: commutative, associative, identity, and distributive. Each property is explained with examples, focusing on how they apply to addition and multiplication. The commutative property allows numbers to be rearranged in addition or multiplication without changing the result. The associative property shows that grouping numbers differently does not affect the outcome. The identity property highlights that adding zero or multiplying by one leaves a number unchanged. Lastly, the distributive property demonstrates how to multiply a number by a sum or difference using distribution.

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

• Associative Property

• Commutative Property

• Distributive Property

• Identity Property
