What does the associative property mean?
a. Moving the numbers around to make the problem easier to solve
b. you can break a number a part, multiply each part separately, and then add the products.
c. Changing the order of two numbers when you add or multiply doesn't change the answer.

Rewrite the problem using the associative property and solve the problem:
(32 x 25) x 4=
32 x (25 x 4) = 3,200
276 / 12 =
