The associative property is normally invoked in the context of two (or more) occurances of a binary operation.

eg (2*3)*4 = 2*(3*4).

Here, you could break down 16 into 2*2*2*2

So that 16*20 = 2*2*2*2*20 which, by the ASSOCIATIVE property can also be written as 2*(2*(2*(2*20)))

= 2*(2*(2*(40)) = 2*(2*80) = 2*160 = 320
