Easy Squaring Shortcut 4

 Finding Square of a number which is between 50 – 75
1.Assume, we have to find the square of N. First find the difference with 50
  (lets say the difference is D)
2. Find the square of D. It will give the last 2 digits of square.
3. Add D from 25, ie find  (25+D). It will give us the first two digit of square.

Ex: Find the square of 52
1.   Find out how far is the number from 50. Eg: 52 is 2 units far from 50
2.   Square the above number. The result will be the last two digits of the required result. i.e., 2*2 = 04, which is the last two digits of the required result. __04.
3.   Add the initial difference of step 1 to 25 i.e., 25 + 2 = 27, this will be the first two digits of the result. 27__.
Hence, Answer is 2704.
