The Associative Property of Addition states that the way in which numbers are grouped in an addition problem does not change their sum. Therefore, you can rearrange the parentheses in the expression \((7 + 8) + 6\).
Using the Associative Property, you can rewrite the expression as:
\[ 7 + (8 + 6) \]
Both expressions \((7 + 8) + 6\) and \(7 + (8 + 6)\) will yield the same result when calculated.
