Dear Readers,

If you want to qualify any exam, then in most of the exams
you need to do faster calculations. Doing faster calculations will let you
solve your questions quickly

Suppose you have to find the square of 35. What you will
normally do is to multiply 35 with 35 and find the product. But doing this
multiplication takes time much longer than this trick. This trick will let you
do square root of any number ending in 5 in seconds.

Here the number is 35. So for the number 35, divide this number in two parts i.e. left part
and right part. The shortcut trick is to multiply the left part to itself added
1 in it. Here the left part is 3. So multiply 3 to itself added 1 in it. Means 3*(3+1)
which is 12.

Now square 5 which is 25. This is our right part of the
answer. 25 will always be there for all two digit numbers ending in 5 which we have to square.

Now our answer is left part|right part means 12|25 means
1225. So square of 35 is 1225.

similarly,

45^2= 4 X (4+1) /25 = 4 X 5/ 25 = 2025

75^2= 7 X 8 / 25 = 5625

115^2= 11 X 12/25 = 13225

This shortcut trick will let you solve squaring of
two digit numbers ending in 5 quickly in seconds. Also it is a simple trick to
remember and will let you solve squaring of two digit numbers ending in 5
