How this math genius solved this problem

(A-B).(A+B) = (A^2 - B^2)

He is Scott wu founder of chat gpt! 😊

No shit idiot the question was simple 7th grade maths it was just his speed that was insane

this is the worst thing measure geniusness

I was amazed when i realized you can just find the average value for this and multiply the thing by 2.

Oh so 9th class maths can be this imp

Guys it’s not that hard

And he did this in 1 second...💀

he is smart like sigma he should get the nopel price

Wasnt Einstein a physicist?

I'm still reading the question and he already buzzed in?

I've watched this video 10 times and I still don't get it

That girl would be like "wait what"

Fascinating Extraordinary Magnificent Champion ❤😊

ooobviously! pfff

Just use calculater

What about the next question?

This app is like a treasure trove of knowledge. It's so easy to use and super helpful.

BS video, einstein hated math. his first wife was the mathematician.

If you're wonderi-
Asian He asian

This is 8th class maths

No bro he didn't took this much time

I don't know, very easy question asked in Olympiad😮

ye bacha tu einstein hai lakin iss ka pota (einstein ka pota ) hamari claas me parta hai😂😂

The girl be like :w

So 255 means 5000 next time some one ask me what’s 255 it’s 5000 like saying 5 plus 5 is 10

Huh what ?

What he did is that he memorized all of the questions and answers for this contest. This clip doesn’t show it, but subsequent questions are literally impossible to finish as fast as he did.

For his age he should know this, but his speed is good.

255² - 245²
Edit 1: its only my solution
As a 8 year old, i can solve this. (Because i am best in math.)
First. Calculate 255²
255²= 510
Second, calculate 245²
245²=490
Now, We know the calculation. So that means we will do
510-490=20
Leave a like if u like this solution!

Its just simple 8th grade math, but the time he took to answer it is just straight up mind blowing

the answere is very simple iam the 1st year student of ics and i love maths so much iam the only one girl in 33 students of my class who take maths subject my all friends hate math cz they say that maths is difficult but for me maths is so interesting😌

he cheated

Can spend an entire day studying this shi and still don't understand

THE GENIUS MIND BEHIND COGNITIVE AI SUPREMACY

"two hundred and f........" beeeeeepppppp 5000.

The question is cakewalk but the speed of the kid unimaginable

I think the question was already displayed in the screen before the host called it out

Ye hamare yaha 4th class me padate he

Fuck offff... just a 3 second question
Use a²-b² = (a+b)(a-b) = (245+255)(255-245)= 500x10=5000

It took me 8 seconds to do 😢
i think i am just very dumb😂

That kid answered by the time i was putting the values in the (a+b) (a-b)

How the difference of two squares actually works:

255² - 245² =
255² - (255*245) + (255*245) + 245² =
(255*255) - (255*245) + (245*245) - (255*245) =
255(255 - 245) + 245(255 - 245) =
(255 + 245)(255 - 245) =
(500)(10) =
5000

Or generally:
a² - b² =
a² - ab + ab - b² =
a(a - b) + b(a - b) =
(a + b)(a - b)

Bruh, i did the same method he did, but i took like 9 more secnonds than he did

Bruh, how can u call him genius, i think it's taught in grade 5, u don't have to be genius for that

I think as soon as the kid saw the two squared numbers, he recognised the latter right away. So he moved to add the base numbers right away (probably the most tedious part) and did the super easy subtraction and multiplication parts in a jiffy.

What

Being fast in math isnt what made einstein a genius,only dumb people are impressed by fast mathematics, i highly doubt this kid will produce anything near what einstein did

There is another method :
It's (250+5)^2 - (250-5)^2 =
2x 2x250x5 =5'000
