6. Commutative Property of
Multiplication

The order you multiply numbers does not
change the product.

-5 x 10 = 10 x -5
Define the properties
of multiplication.

7. Associative Property of
Multiplication


Changing the grouping of numbers when
multiplying does not change the product.
1 x (2 x 3) = (1 x 2) x 3

ORDER STAYS THE SAME, JUST THE
GROUPING CHANGES.

8. Identity Property of
Multiplication


Multiplying by 1 will not change the
identity of the number
-29 x 1 = -29

9. Zero Property of Multiplication

