The next part

hi,

Now for the next range of 75-125

In this case you take the number and 100.

Take 94 and 112 for instance.

94 -> 100-94 = -6

now add this -6 to 94 which give 88(1st 2 digits)
(-6)^2 = 36(last 2 digits)

hence 94^2 is 8836.(Check using calculator:))

Now for 112 the same process

112-100 = 12 add this to 112

112+12 =124

(12)^144 here 1 is the carry, so 112 ^ = 12544.

So this is how we can  calculate squares from 26-125 very easily.

Cheers!!
