Easy Squaring Shortcut 3

 Finding Square of a number which is less than 100
1.  Assume, we have to find the square of N. First find the difference with 100 (lets say the difference is D)
2.  Find the square of D. It will give the last 2 digits of square.
3.  Find the difference between the number (N) and Difference (D) i.e. find  (N-D). It will give us the first two digit of square

Ex: Find the square of 93
The deficiency of 93 is 7 because it is 7 less than 100 (base). Now, 93 – 7 = 86. This gives us the left-hand part of the answer. The square of the deficiency is 7 × 7 = 49, and this is the right – hand part of the answer. The working can be done mentally and the answer, 8649, written straight down.
