Simple Squares and Square of Any Number -Vedic Maths

Square Techniques and shortcuts of vedic maths for competitive exams 

There are many problems in which we have to compute the square of a number, i.e. multiply a number by itself. E.g. square of 625, 3.3859 etc. Vedic maths provides a powerful method to compute the square of any number which is asked in competitive bank exams of any length with ease and get the answer in one line. lets see how we can able to use shortcuts and tricks of vedic maths into any square techniques.

Example : Number ending with 5

Numbers ending in 5 Consider the square of 35. The technique is very simple and consists of two steps.
Steps: Multiply the first number ie. 3 by the number next to it i.e. multiply 3 by 4 and write down the result as 12.
and multiply the second digit 5 itself to 5 and attach in to last.
3*4 = 12
5*5 = 25
      1225

this is look awkward right? we want to solve all the digits not only that ended with 5 ? we need static shortcut then, wait lets see the below example too 😉

How to solve Squares of any two digits number

now from following method we can crack any of the 1-99 numbers. lets practice again if we can crack 73’s square.
73 = 49-42-9  = 5329

so we select 9 as a last digit which is square of 3. after that we calculate 2 with no figure cause 9 was single digit number and then we calculate 49+4= 53.

lets say how to square 85 on this vedic maths trick?

85 = 64 | 8*5=40*2=80 | 25

lets select 5 at the last,
then calculate 0+2=2
now calculate remaining 8 with 64 8+64 = 72

7225

wow that is epic but how we can square of 3 digit number?
simple, follow this example.

shortcuts of vedic maths to solve three digit square

124 = 12’s square | 12*4=48*2= 96 | 4’s square
       =  144 | 96 | 16
       =            15376
