Associative Property of Addition states
(A + B) + C = A + (B + C)
Applying it to (7 + 11) + 2 you can rewrite it as 7 + (11 + 2)

(7 + 11) + 2 is the same as
7 + (11 + 2) or
(7 + 2) + 11.

i think you would do 7+(11+2) im pretty sure all that means is that you rearrange the numbers and the sum is still the same.
