Properties of Numbers: Associative Property of Addition

The video uses gummy bears to illustrate the associative property of addition, showing that numbers can be grouped in different ways without changing the sum. It explains the concept using examples and demonstrates how parentheses are used in mathematical expressions to group numbers, emphasizing that the sum remains the same regardless of grouping.

Provide an example of how the associative property works with the numbers 2, 7, and 3.

How does changing the grouping of numbers affect the sum according to the associative property?
