Which property of addition is shown? 7 + (1 + 2) = (7 + 1) + 2 Choices: (A)associative (B)commutative

Identify Structure: Step 1: Identify the structure of the equation. The equation shows a number added to a grouped addition on one side and a different grouping of additions on the other side. Recall Properties: Step 2: Recall the properties of addition. The associative property allows us to change the grouping of the numbers that are being added without changing the sum. The commutative property allows us to change the order of the numbers being added. Match Property: Step 3: Match the property to the equation. Since the grouping of the numbers is what changes between the two sides of the equation, this is an example of the associative property.
