The associative property means to "re-associate" the numbers, keeping them in the same order. In this one, what is given "associates" the 10*5 by parentheses. Associative property means to associate the 5*20 instead. Of course, the result is the same!!

(10*5)*20 =10*(5*20)

R^2

P.S. Please note that the solution posted by Checkley is INCORRECT! By the ASSOCIATIVE PROPERTY, the ORDER of the factors NEVER changes! Switching the order of multiplication as Checkley did is the COMMUTATIVE PROPERTY, NOT the ASSOCIATIVE PROPERTY!!
