Shortcut for squaring any 3 digit number..
For e.g 209 , 816 , 712
Note: The answer will be of 6 digits.
Let the answer be of the form a b c d e f.
Let us find the square of 209
Step 1: Separate the digits of the input number as 2 and 09.(So if the input number is of the form pqr, separate it into p and qr.)
Step 2: Square the first digit of the input input number. i.e. (p^2) = (2^2=4) . This makes the ab part of the answer. So the answer now becomes0 4 c d e f
Step 3: Square the remaining part of the input, i.e the last two digits or qr. (qr^2= 09^2 = 81)This makes the last two digits of the answer.So now the answer becomes of the form 0 4 c d 8 1.
Step 4: Now to find c d in the answer, simply multiply the two parts of the input numbers together and then with 2. i.e. p * qr * 2= 2*09*2 = 36.
Answer now becomes 043681.
Note: Just remember that the square of the last two digits of the input number, can accommodate only the last two digits of the answer, Hence transfer the carry(if any) to the digit on the next place.
For e.g. (712)^2 .
Step 1: Separate input no. into 7 and 12.
Step 2: Square of first digit of input = 7^2 = 49
Ans. 4 9 _ _ _ _Step 3: Square last two digits of input number, i.e, (12)^2= 144.
Now in the answer the last two digits will be 44 and the 1 will be carried forward.Ans. 4 9 _ ( _ + 1) 4 4.
Step 4: 7*12*2 = 168
Even here carry will be forwarded
.Ans = 4 (9+1) 6 (8+1) 4 4 = 5 0 6 9 4 4
