Multiplication of numbers
In VM we use multiplication of two numbers from left to right mentally .
suppose 234 x 3
here you multiply 2 by 3 then 3 by 3then 4 by 3 , but In conventional maths we do it from right to left for that we have to use pen and paper , but in VM if we do from left to right we calculate it mentally.
= 69(1)2 here (1) is the carry
=702 1 added to 9 we get 10 , then 6 added to 1 of 10 we get 7
Any number of digits we can do calculate mentally using Left to Right Approach of VM.
One More than the One Before-Sutra of VM
When first digit of two numbers are same and last digits added to 10 of two numbers then we use One more than the one Before sutra of VM.
Multiply 53 x 57
here 1st two digits of two numbers 53 and 57 are same ie 5 .Last digits of two numbersadded to 10 i.e 3 +7 = 10
= 5 x ( 5+1) | ( 3 x 7)
=(5 x6) | ( 3 x 7)
= 3021
here next number of 5 is 6 i,e one more of before number 5 is ( 5 +1) i.e 6
First by First and Last by Last - Sutra of Vedic Maths
Multiply 48 x 68
here last digit in both numbers are same. and sum of 1st digits of two numbers is 10 . i.e 4+6=10
= (4 x 6)+8 | (8 x 8)
=3264
This sutra is known as " First by First and Last by Last " of Vedic Maths
