Hello friends,
Checkout this video on "How to find Squares of any Number 1-100?" | Squares of any Numbers in 3 Seconds by Letstute.

In this video, we have found the squares of any two-digit number in just 3 seconds without using a calculator.
When we multiply a number by itself, then the outcome is known as the square of that number.

In this Video:
Six easy steps to find squares of any number in just 3 seconds are:
1. Take the square of 1st number
2. Take the square of 2nd number
3. Add a zero below the last digit
4. Multiply 1st and 2nd number
5. Multiply the solution that you got by multiplying 1st and 2nd number by 2.
6. The final step, add these two numbers.

Thank you for watching.

Mam,
Why to remember these steps??

You had used a simple formula (a+b)² = (a² + b² +2ab)

Eg. 56² = (50+6)² = (50² + 6² + 2×50×6)
=(2500 +36 +600)
=3136

Hy ma'am, you missed 1 step here, in second step when we square the unit-digit number, if the square is two digit number then it's ok but in case the square of unit digit number is single digit number then we must add a zero before it to make double digit number.

For eg: if We're squaring 21 then, sqr of 2 = 4, and sqr of 1 = 1 but we must consider 1 as 01 so that we can get 401 instead of 41. If we take 41 we get wrong answer. See how 👉 41 + ( as step four & five suggest multiplication of 1st and 2nd number: 2x1= 2, then doubling the product of it: 2x2 = 4, and as step three suggest to put a zero on the right side of 4, it becomes 40 then after adding 40 to 41 we get 81 that's wrong answer.

Ultimately awesome😍. There's a confusion in finding the square for 21

If I want to know the square of 52 then I used this method but the answer comes wrong and same with 62

[dipikabahl]

Best for students of 7th to 10th standard (Like me). Respect for people who make videos like this!👍😌🧐

[tylerd.]

Thanks, Mr. Fox’s class is an awesome class but I don’t study and this is the video just for me. Thanks!

[stutisinha]

Mam plz tell few steps to find root of any number

[thomasisaac]

Thank u so much . I have an exam coming on compound interest . In almost all questions the last step is to find squares of very big numbers. This helps me a ton and saves lot of time.

[jotarojoestar]

This trick doesn't work on imperfect square like 43 = 169+240 = 409 and if you multiply 43x43 = 1, 849 this is the actual square

[dhruvbhatt]

The video starts at 1:10. Thank me later

[emilyc]

Do I use the same steps if I want to find the square of three-digit numbers? Thanks
And I love the video so much! Helps a lot~

[pihumandavat]

Helped me a lot because I missed the session when my teacher taught me .
Thanks 🤗

[kartikeysinghal]

you can't take out of the squares of the numbers which are till 3
like 32: you will get the answer 214 by this method but when you do the calculation you get 1024

[ASHKILLERZedits]

Why It has so few numbers of views and like, It deserves more, Thanks a lot. :)

[ganavigv.]

We can't find the answer for (51) square ... We can't get the correct answer...if we do in this method...

[suryaveersinghchouhan]

All the best for your exams hope you all are success 👍😊

[Dikshasharma]

Thank you so much mam it's to easy to solve thank you.

[rasikaauti]

Ohh wow this method is amazing!!!
Thnxx for this video mam😇😇
It will definitely help me in my bored exam👍🏻👍🏻

[chagmenlietons]

If you know the square of the first number, you can 'step up' to the next number in line without having to go through this method every time, using the following equation.

If the known number is 'y':

x = y - 1

Or if you know x:

y = x + 1

Then use this basic expression to check.

y^2 - x^2 = x + y

This basically means you can add x and y and then add or subtract that to the known squared number to step up or down to the next unknown number in line. I haven't bothered doing this with decimal numbers, but it should help with finding the next whole number in line. :)

Thankyou
This is very easy trick to find out the squares
