## About Squaring Technique

Many readers have requested me to teach them a simple method to square two and three digit numbers. In bank exams calculation speed is very crucial. So today I have decided to explain my Squaring technique

## Technique

In case of two digit number deduct last digit and add it to another number and then add square of same.

In this technique we simplify the squaring method by making one unit’s digit zero. It is far easy to multiply 50*24 than 54*24. So I used this technique. Try practice more to become expert in this technique.

## Let’s take some examples

**Find square of 53.**

=(53*53)

= (53+3) * (53-3) + (3*3)

=(56*50) + 9

= (560*5) + 9

= 2800 + 9 = 2809

**Let’s take another example**

Find square of 69

= (69*69)

= (69+1) * (69-1) + (1*1)

= (70*68) + 1

= (680*7) + 1

= 4761

**Let’s take one more example**

Find square of 45

= (45*45)

= (45-5)*(45+5) + (5*5)

= (40*50) + 25

= 2000+25

= 2025
