Lets multiply using commutative law and associative law


As per the Commutative Law of multiplication,


a b = b a = ab = ba


The product is , which will result in calculating either of the following expressions :-


•


•


As per the Associative Law of multiplication,


a (b c d) = (ab c) d = abcd = abcd


The product is , which will result in calculating either of the following expressions :-


•


•[{
