PROPERTIES OF MULTIPLICATION

PROPERTIES OF MULTIPLICATION :-

1. The product of a number by 1 is the number itself.

Example: 3,78,762 x 1 = 3,78,762


2. The product of a number by zero is always zero.

Example: 34,764 x 0 = 0


3.  Commutative property of multiplication:-

The product of two numbers does not change when we change the order of numbers.

Example.1)   25 x 20 = 500,  and   20 x 25 = 500

25 x 20 = 20 x 25


4.  Associative property of multiplication :-

The product of three numbers does not change when we change their grouping.

Example: (35 x 20) x 30 = 700 x 30 = 21,000

35 x ( 20 x 30 ) = 35 x 600 = 21,000

(35 x 30) x 20 = 1050 x 20 = 21,000
