if you know that 8 time 7 is 56 , how can you use the commutative property of multiplication to find the product of 8 times 7

Well, if you know that 8 times 7 is 56, you can certainly use the commutative property to find the product of 8 times 7. You just have to close your eyes, spin around in circles seven times, shout "Multiply!" and hope that the numbers rearrange themselves magically. Just make sure you're not standing near any delicate objects, or you might end up with a messier situation than trying to solve the math problem!
