MULTIPLICATION - PROPERTIES OF MULTIPLICATION

PROPERTIES OF MULTIPLICATION :-


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

    Example: 8,22,792 x 1 = 8,22,792


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

    Example: 25,765 x 0 = 0


3. The product of two numbers does not change when we change the order of numbers.  (Commutative Property of Multiplication)

    Example:  25 x 30 = 750      and     30 x 25 = 750

    ∴   25 x 30 = 30 x 25


4. The product of three numbers does not change when we change their grouping. (Associative property of Multiplication)

    Example: (25 x 20) x 40 = 500 x 40 = 20,000

               25 x (20 x 40) = 25 x 800 = 20,000

               (25 x 40 ) x 20 = 1000 x 20 = 20,000
