Multiplication Of 2 Two-Digit Numbers

Rajiv Singh
11/09/2018 0 0

Multiplication of 2 two-digit numbers where the first digit of both the numbers are same and the last digit of the two numbers sum to 10.

Let me explain this rule by taking examples:

To calculate 56×54: 
Multiply 5 by 5+1. So, 5*6 = 30. Write down 30.
Multiply together the last digits: 6*4 = 24. Write down 24.
The product of 56 and 54 is thus 3024. 

Example:

Understand the rule by 1 more example
78*72 = [7*(7+1)][8*2] = 5616.
