Vedic Mathematics - An Introduction by Dev M

VPS 1 : Multiplying any number by 11

P.S: The number must be a 2-digit number.

Steps:

1. Add the 2-digits of the number together.
2. Place the sum of the two-digits between the 2 digits to get the answer.

Eg:

21x11->2+1=3, Answer=>231

36x11->3+6=9, Answer=>396

29x11->9+2=11(a 2-digit number, hence, 1 gets carried over), Answer=>319

VPS 1: Squaring Numbers Ending in 5

Steps:

1. Add 1 to the digits that come before the digit 5.(Eg. add 1 to 2 in case of 25 squared)

2. The first part of the answer is the number(consisting of the digits that come before 5)times the number you get be adding 1 to it(here, 2x3=6)

3.The second part of the answer is simply 25.

Eg 1:

For, (35)²->3+1=4, 3x4=12 , therefore answers=>1225

Eg 2:

(65)²->6+1=7, 6x7=42 , hence, answer=>4225
