PROPERTIES OF MULTIPLICATION

PROPERTIES OF MULTIPLICATION -

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

       Example: 2,38,752 x 1 = 2,38,752

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

       Example: 40,598 x 0 = 0

3. Commutativepropertyofmultiplication:

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

Example: 15 x 20 = 300 and 20 x 15 = 300

                ∴ 15 x 20 = 20 x15

4. Associative property of multiplication :

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

          Example: (15 x 20 ) x 40 = 300 x 40=12,000

                          15 x (20 x 40) =15 x 800 = 12,000

                           (15 x 40) x 20 = 600 x 20 =12,000
