How to quickly square a two-digit number that ends in 5
?
For example, 35
Step 1: Multiply the first digit by itself plus 1.
Step 2: Put a 25 at the end.
35 squared = [3 x (3 + 1)] & 25

[3 x (3 + 1)] = 12

12 & 25 = 1225

35 squared = 1225

What do you eat to know these things? And I am very thankful for you effort you put in these mathematicalvideos, you're a life-saver! You deserve the square of your current number of subscribers!!

[snehaagrawal]

Oh my God. Thank you so so much! This made my calculations so damn much easier.. I'm very glad, thankful and grateful that channels like Don't Memorise exist.. honestly!!

[simonepozzari]

Thank you, that's the easiest method I've ever learnt!

[snakequeen]

you could also do this: 2nd+d^2 where n is one of the numbers you start with (pick a square you know or a close ten) and d is the square roots, the higher one subtracting the lower one. for example the square of 27 by using 20 as an anchor number= 2(20)(7)+7^2=280+49=329. 329+ 400(meaning 20^2)=729 or 27^2

i will tell you an easy way to find square no.
you know the identity that is
(a+b)^2 =a^2+2ab+b^2
then for example let us take 12.
now first digit of no. will be A and the second digit B
now apply the identity:-
a^2+2ab+b^2
(1)^2 | 2×1×2 | (2)^2
1|4|4
so you get the answer 144
you can try that method on any two digit number
thank you..

Hey how to find square of 47 in this way??? It becomes more difficult instead of this we can do normal multiplication

[vanilla_cookies]

I had another method for xy^2 for ex 34^2, you just quare the last digit, 4 which is 16 then take 1. Next you multiply the first digit to 2 then to the last digit, 3 x 2 x 4 which is 24 and add 1 you take to 25 then continue to take 2, finally quare the first digit, 3^2 is 9, and add the 2 you take to 11. So 34^2 is 1156

every time we need to take the number like 10, 100, 1000 or can we even take number such like 30 40 50 if they are near to square number

I love this series. A lot of people keep asking for more obscure examples. They have a whole website that goes over the other cases specifically if you're curious. A lot of people keep asking what if its 74 or 43 or 61 etc etc. They cover that example as well on their website but you basically do the same thing. Base 10 times the multiple. So in this case 74 - base 10* 7; 43 base 10 * 4; 61 - base 10 *6. Same steps just 1 small tweak before the final answer. I would check out their site I just found them recently and their way of teaching you to think about numbers differently is absolutely beautiful.

underrated
will help me a lot with maths because don't understand anything in online classes

[rajshribhakare]

It is all because of our brilliant Indian scholars I proud of my india

[satyenkulkarni]

what video editor do you use?
can't wait for next episode/video...😀

[tanwichakraborty]

Being a fan of math I loved this method

[ngalathemkashung]

Thank you. It helped me a lot. I wish I had known this technique before

[vijayalakshmi-hrbi]

where are you from?
your math tricks are really very good mam
I don't know how you guys are finding these tricks
don't forget to answer me for where are you from?

[bhavaniganti]

Tq so much to this excellent channel and way of teaching... Idk how I really change and find a new way to find out that square root it is real better than this. But this credit also goes u only to made me like this😍🥰😘❤❤❤❤❤❤

[dahiruahmed]

VERY VERY INTERESTING METHOD. BUT WHAT OF IF THE NUMBER IS MORE THE 20 LIKE 67, 34, 27 ETC? THANK

[harshalagharat]

Thank you very much this method is the easiest method for finding squares
