2.3.1 Laws of Multiplication

 We have studied the laws of addition of whole numbers. Now we
 discuss the laws of multiplication which are given as follows:
 â€¢	 Commutative Law
 Consider any two whole numbers, say 2, 3 and multiply them in the
 given order:

                                         2Ã—3=6
 Now change their order and perform the multiplication again:

                                         3Ã—2=6
 Hence, the result is the same after changing their order. So,

                          a x b = b x a for all a, b ddW
 This result can also be verified by using a number line.
