Trick to Square any Two Digit Number Quickly

Hello Guys
Today I'm going to show you how to square ANY two digit really fast. This trick is dedicated to the school going students who want to speed up in the mathematics exam.So lets began

1.Write down the number

 Let us assume we are squaring the no. say 49. Just write 49 somewhere.

2. Square the no at the ones place

 We are considering 49 so 9^2 = 81.

3. Write down the digit at ones place so obtained and consider the no. at tens place as a carryover.

Since  we are squaring 49,  We have ___1 on the paper. and 8 as a carryover.

4. Now Multiply both the digits with each other and multiply the result by 2.

We have 4X9 = 36 X 2 = 72.

5. Now add the carryover to this number and write down this numbers ones digit at the tens digit of the squared number

We have 72+8 = 80 The no is __01. Carry is 8

6. Now square the number at tens place and add this to the carryover.

We have 4^2 = 36. And 36 + 8 =44

7. Write down this number preceding the previous number. 

We now have 4401

Congrats You have just squared it!
