Changing the grouping of the terms does not change the sum.
Associative Property of Addition
Practice makes perfect
To identify the Property of Real Numbers being demonstrated by the given equation, we should first identify the operation being performed.
2+(12+r)=(2+12)+r
In this case, the terms are being added. The equation shows that changing the grouping of the terms being added does not change the sum. This is the Associative Property of Addition.

The Other Properties
In this exercise, we saw an example of the Commutative Property of Addition. Now, let's review the other Properties of Real Numbers.
Distributive Property: This property shows that the product of a number and a parenthetical factor is equal to the sum of the products of the number and each term inside the parentheses.
