Question 818594: I have the following two problems:
3(2/3 + 3/4) = 3(3/4 + 2/3) I think it's commutative property of addition because you are not regrouping (associative) but are reversing the order of the addition. Is this correct as commutative prop of addition?
7(4 � 5) = 7(5 � 4) I think it's commutative property of multiplication because you are not regrouping (associative) but are reversing the order of the multiplication. Is this correct as commutative prop of multiplication?
