COMMUTATIVE PROPERTY OF MULTIPLICATION

About "Commutative property of multiplication"

Commutative property of multiplication is nothing but the rule which says that, when we are doing multiplication, it doesn't matter, in which order the numbers are.  We can multiply a and b or b and a ... and we'll  get the same answer. 

More clearly,  a x b  =  b x a
