ok thank you you are a big help
In 1., all that was changed was the order of the multiplication. Think of n + 6 as A. A * 7 = 7 * A A change of order is the commutative property of multiplication.
In 2., the grouping changed. On the left, you need to do 4 * 9 first, then multiply by 3. On the right side, 3 * 4 is done first, then it is multiplied by 9. The grouping has changed. Change of grouping is the associative property of multiplication.
ok thank you
ps not to be rude the answers were a b b a
but it is ok
3. is like 2. The grouping changed. Associative. 4. is like 1. The order changed. Commutative.
ok
