I think I just need the answer not how-

The property of arithmetic used to rewrite the numeric statement is the associative property of addition. This property states that for any three numbers a, b, and c, the sum will be the same regardless of how the numbers are grouped together. In this case, the numbers 6, 3, and 21 are being added, and the associative property allows us to rearrange the numbers without changing the sum.
