Identity of Multiplication 


Associative of Multiplication 


Distributive 

@shamil98 and @mathstudent55

Answer 6

The commutative property means change of order.
The identity of multiplication is 1 since a * 1 = a.
Associative property is change of grouping.
Distributive is a(b + c) = ab + ac.
What does this look like to you?
