# Short trick to find square of a number

Every one must have learnt the square of 1-30 but going above would definitely be tough. So, let’s discuss the simple trick to learn square of numbers between

First, 31-50 numbers.. Take example: Find the square of 34 ?

1. 50

2. Now, 50-34 = 16.. Then square it.. 162 = 256..

3. Or 256 number mein bi “56” ki jarort h.. Or hundred place k number.. i.e. 2 will be used as a carry number.

4. Now, subtract 16 (from step 2) from 25 (got from step 1).. 25-16 = 9 and then, add carry number “2” to “9”. Then, answer is 9+2 = 11..

5. Here is your answer. Take “56” (from step 3) and “11” (from step 4).. Square of 34 = 11-56.. 1156

Use the same procedure for number from 31-50.. You will get the square easily.

__&__**31-50****50-75.**First, 31-50 numbers.. Take example: Find the square of 34 ?

1. 50

^{2}= 2500.. Isme last 2 digit hta do.. Sirf.. Number 25 is important in 2500..2. Now, 50-34 = 16.. Then square it.. 162 = 256..

3. Or 256 number mein bi “56” ki jarort h.. Or hundred place k number.. i.e. 2 will be used as a carry number.

Use the same procedure for number from 31-50.. You will get the square easily.

**The same procedure will be followed for number.. 51-75..**

But, there is a slight change..

Take example: find the square of 67..

1. 67-50 = 17.. Do the square of 17 = 289.

2. Keep “89” aside and “2” will treated as carry number.

3. Now, add 25+17 (similar step4 above mentioned..yeh jada h 50 s.. Th add kiya vh kam tha th subtract kiya tha)= 42, and then add carry number “2”.. 42+2=44.

4. For the answer, take 44 and 89 (step 3 & step 2) and put them together.. You will get the answer – 4489 (square of 67).
