4(7)(5)= 4(5)(7) associative property or commutative?

I don't really get the difference between the two properties.

**jim**, Tuesday, October 20, 2009 at 8:16pmActually, what yu've written is a bit of both.

Commutative is:

4 + 5 = 5 + 4

Associative is:

(4 + 5) + 2 = 4 + (5 + 2)

So 4 * (7*5) = (4*7) * 5 is Associative.

but

5*7 = 7*5 is Commutative.
