The Associative Property of Addition states that the way in which numbers are grouped does not affect their sum. This means that you can add the numbers in a different grouping.
For the expression \((7 + 8) + 6\), you can regroup it as follows:
\[ 7 + (8 + 6) \]
So, the equivalent expression using the Associative Property of Addition is:
\[ 7 + (8 + 6) \]
