Multiplying by 9, 99, 999, 101, 1001 and so on
To multiply a number by 9, we multiply the number by 10 and from the
product, subtract the number (multiplicand). To multiply a number by
99, we multiply the number by 100 and from the product subtract the
number. The process goes on for large numbers too.
Examples:
1. 5,048 x 999 = 5,048 (1,000 - 1)
= (5,048 x 1,000) - (5,048 x 1)
= 50,48,000 - 5,048
= 50,42,952​

number. The process goes on for large numbers too.

Examples:

1. 5,048 x 999 = 5,048 (1,000 - 1)

= (5,048 x 1,000) - (5,048 x 1)

= 50,48,000 - 5,048

= 50,42,952
