 Question 151602: if (7+4) x 2 = (4+7) x2, then this is by the commutative law of addition. at first it looks like the distributive law of multiplication with respect to addition, but, in fact, the only difference in the two equations is that the 7+4 becomes 4+7 or a+b=b+a, which means the law that applies here is the commutative law of addition. is this correct?
