SQUARE OF NUMBERS NEAR TO 100

 

Let me explain this rule by taking examples
96^2 :-
First calculate 100-96, it is 4
so 96^2 = (96-4)—-4^2 = 9216
similarly
106^2 :-
First calculate 106-100, it is 6
so 106^2 = (106+6)—-6^2 = 11236
EXAMPLE.
An other case arises
110^2 = (110+10)—-100 = (120+1)—-00 = 12100
similarly
89^2 = (89-11)—-121 = (78+1)—-21 = 7921
