# Square a Two-Digit Number

## (The Magic Of Math)

In the previous blog we had read Multiply any two digit number by eleven , today we’ll learn another magic and that is…

Square a two-digit number that ends in 5

For this we need to remember only two things.

1. The answer *begins *by multiplying the first digit by the next higher digit.

2. The answer *ends *in 25.

For example, to square the number 35, we simply multiply the first digit (3) by the next higher digit (4), then attach 25.

Since 3 X 4 = 12,

the answer is 1225.

Therefore, 35 X 35 = 1225.

Let’s take another example,

Square of 95 = 95 X 95

= multiply the first digit (9) by the next higher digit (10) and attach 25

= ( 9 x 10) 25 = 9025

So, the answer is 9025.

With even more practice, you will be able to perform many calculations faster than someone using a calculator.
