How to Calculating Square of numbers quickly (Vedic Maths )

Calculating Square of numbers quickly...

Lets calculate the square of 54

So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916

 (55)^2 = 5^2 +5 --5^2=25+5------25=30---------25= 3025

 (56)^2 = 5^2 + 6--6^2=25+6------36= 31--------36= 3136 etc..

How to Multiply Any Number With 12 (Vedic Maths)

Multiply any large number by 12 mentally in seconds

To multiply any number by 12 just double last digit and thereafter double each digit and add it to its neighbor

For example 21314 * 12 = 255768

Lets break it into simple steps:

Step 1: 021314 * 12 = _____8 (Double of Last Digit 4= 8 )

Step 2: 021314 * 12 = ____68 (Now Double 1= 2, and add it to 4, 2+4=6)

Step 3: 021314 * 12= ___768 (Now Double 3=6, and add it to 1, 6+1=7)

Step 4: 021314 * 12= __5768 (Now Double 1=2, and add it to 3, 2+3=5)

Step 5: 021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

Step 6: 021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of 21314 * 12 = 255768
