Don’t Know , So what , I know the Other way

Squaring of  Two Digit Number

Rule:
1) Find the  reverse  of a number.
2)  Find the square of reverse of number.
3) Find the difference of square of digits.
4) Add it to 1st two digits of step2. And subtract result of Step3 from last 2 digits.
5) Atlast result is obatined.

Let’s take an example to understand in much better way.

Consider squaring of 58.
  52 ^2 =???
     25 ^2
     Ending in 5
Therefore 25 ^2 =
         =2 (2 +1)/25
         =625.
   Now  5^2 -2^2 =25 -4
                     =21.
   25^2 = 06 / 25
    Add 21 to 06 and subtract 21 from 25.
We get 27 /04
Therefore , 52^2 =2704.

Example 2:-
           62^2 =??
      26^2 = 0676.
    Now 6^2 -2^2 = 36-4 =32
Now add 32 to 06 and subtract 32 from 76.
We get
62^2 =38/44
Therefore,  62^2=3844.
