if you know that 7* 8=56 , how can you use the commutative (Order) Property of Multiplication to find the product of 8*7 ?

you just did. The property means that
8 * 7
is exactly the same as
7 * 8
In other words the two factors commute, you can change their order without changing their product. This will be true until you get to multiplying matrices.

Remember back when when you were learning addition you had the commutative property of addition which means
2 + 3
is the same as
3 + 2
Now you are getting the same property for multiplication :)
