is
4(7)(5)= 4(5)(7) associative property or commutative?
I don't really get the difference between the two properties.

    Actually, 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.
