Commutative and Associative Properties
Example of Commutative and Associative Properties
Example 1
This is commutative property because if you add two real numbers in any order, the sum will always be the same or equal.
Example 2
This is associative property because if you are adding three real numbers, the sum is always the same regardless of their grouping.
Identity Properties of Addition and Multiplication
Example of Identity Properties of Addition and Multiplication
Example 1
This is Identity Property of Addition because if you add a real number to zero, the sum will be the original number itself.
Example 2
This is Identity Property of Multiplication because if you multiply a real number to one (1), you will get the original number itself.
Zero Property of Multiplication
Example of Zero Property of Multiplication
