Answer 1

Square of numbers near to 100
-------------------------
Let me explain this trick 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

Now ,
An other case arises
110^2 = (110+10)----100 = (120+1)----00 = 12100
similarly
89^2 = (89-11)----121 = (78+1)----21 = 7921

Answer 2

not only for hundred , it is for every no. near 10,100,1000,10000,etc.

Answer 5

even i didn't get this :

Answer 6

96-4=92
4^2=16
So, it becomes 9216
