Question

different tricks to find square of two or three digits numbers​

Answer 1

to find square between 75 and 125
For example 106
First find the difference of this no from 100
then add the difference to this no.
106-100=6
106+6=112
Now get the square of difference
(6)^2=36
Hence (106)^2=11236
Another example 94
Find its difference from 100
94-100= -6
Then add the difference to the number
94+(-6)=88
then get the square of difference
(-6)^2=36
hence, (94)^2=8836
Another example
124
124-100=24
124+24=148
(24)^2=576
you have to take only last two digits of square of the difference of 100 and 124
and the 3rd number will go for carry
hence, (124)^2=15376
