This is a technique useful for multiplying large numbers with each other, which is evolved from Vedic Mathematics Let us consider an example: Example: say, we want to multiply 65 * 78 6 5 ↓ 7 8 --------- 0, 4 carry 6 5 × (6* =48, 7*5 =35) 7 8 (48 + 35 = 83=> +4carry = 87) --------- 7 0, 8 carry 6 5 ↓ 7 8 (7*6 = 42 => +8 carry = 50 --------------- 5 0 7 0 The answer is: 65 * 78 = 5070 This trick can be extended any larger numbers too.
							
This is a technique useful for multiplying large numbers with each other, which is evolved from Vedic Mathematics

Let us consider an example:

Example:

 say, we want to multiply 65 * 78

 6 5

 ↓

 7 8

 ---------

 0,    4 carry

 

 6 5

     × (6* =48, 7*5 =35)

 7 8 (48 + 35 = 83=> +4carry = 87)

 ---------

 7 0,    8 carry

 

 6 5

 ↓

 7 8 (7*6 = 42 => +8 carry = 50

 ---------------

5 0 7 0

 

The answer is: 65 * 78 = 5070

This trick can be extended any larger numbers too.
