smarter than all the teachers in the us

[Sumanth575]

hw abt 25 square????

[Nash28ish]

lv99iam ....85^2 = 7225

[lv999iam]

It doesn't work for 85 squared?

[pinkpop37]

it doesnt work for 18 squared?

[SrishtiSharma1]

thumbs up to this ;) helped me alot

[HipCherry]

@saffnpepa or 75^2

[rudge1982]

Is their any book on vedic math that you would recommend?

[abraarhabib786]

doesnt work for 17^2

[hasteve101]

@abraarhabib786 Another Verdic trick: 17 is 7 more than 10, so we add 7 to 17. 24. Since we are in the base of ten we can fit in one more didget. 24_. 7^2=49. Since 49 is two didget we carry the 4 over and add it to the other 4. Hence, 24(+4)9=289. Hope it helps.

how about 66^2?

@saffnpepa

For 21^2: 21 is 11 more than 10. So first do 11^2 that is 121....keep that 121 as it is as of right now....Now add that 21 and 11 (21 + 11 = 32)...put this 32 beside 121...(i.e..32121)....Add that 12 into 32 (i.e...[(32+12)1]...)...ans is 441...

For 96^2: 96 is 4 less than 100....Subtract 4 from 96...(96-4) = 92....Now square the difference...4^2 = 16....ans is 9216.......

thanks a lot for u awesome video.

[OutFromEchoes]

Thanks for the video! I've been exploring Vedic mathematics, and had a question - I'm familiar with using the bases of 10, 20, 50, and 100 to find the square, but is there any base I could use to square a number in the 70's or 80's - say, 76, for example? Thank you!

[mstrdk]

hi. your videos are awesome. i would appreciate it if you could post videos showing how to find square ROOTS of BIG numbers.

thanks in advance

[sagar2807]

Thanks for the video.

[Aatifah]

what about 99^2?

[bsnvr]

@Aatifah Watch out my future videos...

[anuragagarwal53]

@Aatifah For all numbers lesser than 100, there is a method to calculate their square:-

Lets take your example i.e. 99^2, its square will be of 4 digits. Divide these 4 digits in 2 Groups say L.H.S. & R.H.S.

For R.H.S. ---99 is 1 less than 100 so square this difference 1 so it will be 1 itself so R.H.S. becomes 01.

For L.H.S.--- Again the difference between 99 and 100 is 1 so subtract this difference from the number 99 gives 98 which is L.H.S.

So the solution becomes 9801

[GiaIsTheBest]

@Aatifah here you use -01.

99 = 100-01

first 2 digits of the answer are 99-01=98

the last digits are -01^2

-01^2 = 01

99^2 = 9801

[sabeershah]

@Aatifah 99 is 100-1...so 99-1 is 98(L.H.S) and just square the 1 which would be 01, so the answer would b 9801, right?

[MrCroky123]

I only wish western countries could teach this. I've been following your videos and I now see calculus with different eyes ...

[sakh06]

How would we take sqaure of a No which is far away from base. For example, 141 or 169 ?

[marla778]

THANK YOU!!!!! I have to take Graduate Record Exam with no calculator.

This HELPS tremendously. They don't teach us this way in the US.

THANK YOU, AGAIN!!!!!!!

[MoskowFreak1111]

holy shit!!! that so f*** simple!! THX!!

can you tell me how to solve a SUDOKU puzzle(any level) in seconds?

How to calculate 172^2 using ur method?

Thanking in advance!

[clericfist]

how is a numbers 0 important if its like this 08 the 0 isnt a place holder right???

[bsnvr]

@clericfist , you are right!, but here, to find the number of digits in RHS, we take count of zero!

[ritikprakash]

HOW TO CALCULATE 55^2 ??

KINDLY HELP !!

[bsnvr]

it's easy : Any number ending with 5 is a special case:

Here, 45^2 , find only 5^2= 25, then make one more than 4, i.e 5 , then multiply 4 and 5, 4 x 5 = 20 , the answer is 2025,

Same way, 35^2 , one more than 3 is 4, so multiply, 3x4 =12, then just find 5^2 = 25, then answer is 1225

[param635318657]

to find 27 square ..it is clear ..it is close to 30 since we usually take 10 and its powers as base.. we take 3*10 as base .. now with a slight change at the arrival of the answer we make it..

that is..27 -3(from 30)

27 -3

take 27-3=24

now multiply 3times 24 since the base is 3times 10 so we get 72

now this becomes the left part of the answer

now this deviation -3 square is -3times-3 is 9club it to the right

we get 729

it can be done easily by practice

[KurdstanPlanetarium]

nice concept but it does not work for 15^2 as 15 + 5 = 20 and square of 5 is 25 so the result is 2025 which is not true but the result should be 225

[thetrufh]

It works. You're using base 10 which means when you square the second digit (5 in this case) your answer should be a single digit and the rest should be carried over. So the "2" in 25 should be carried over and added to 20 to get 225

[KurdstanPlanetarium]

I see in that case then you are right it does work...thanks

[deepakthegreat123]

how do you find 27 sq. Whats the base for that?

[Deadlyphase]

Honestly this is a terrible way to find the square of a number.

For 27, do the following:

2^2 = 4

7^2 = 49

Then tack 49 to the end of the 4

449

2x7x20 = 280

280+449 = 729

That way is MUCH easier. Square the first number, then square the second and tack it on to the first, then multiply the two digits by each other, the times 20, and add that to first part. Will work for any two digit number.
