It took him 1 year to solve the problem. It took him another year to get to the point of telling us what the problem was

[ym-wicp]

I am glad I was at least able to calculate how 4.5 hours for three questions mean 90 minutes for each question on average

[hamzahk.]

I came up with a solution in 4minutes....it was wrong.

Do you know The Legend of Question Six
Me, an intellectual: Why was number six scared of seven?

[adamweishaupt]

"Hey, let's give a bunch of teenagers one of the hardest problems ever conceived in mathematics."

[DefeatLust]

Well, it didn't take me a year but it did take me about 10 hours... it is difficult but if you really think about it, all you have to do is press Right button, Right button, B, Right Trigger, Right, Left, Right, Left, Right, Left into your xbox controller and you can beat gta fairly easily. Your welcome.

"And if you can't figure out that's ninety minutes, you're gonna struggle with the whole exam" You didn't have to attack me like that

[lanvu]

"have you heard of the Legend of question six?"
no, but I've heard of the Emu war 1932

[maximusmawle]

Why doesn’t anybody give credit to the people who designed these questions. They must be even MORE genius.

[bm-brgo]

"Have you heard of the legend of question six?" No but I have heard of thelegend27.

[DavidRussell]

I think one of the biggest reasons I love this channel is that it's not really a maths channel--it's more of a place that tells stories through difficult questions, and often shows you different ways of thinking about these problems. The stories these professors tell are always super enchanting

[colinjava]

I just solved it, but there wasn't enough room here to type it in so I haven't.

[TheWolf]

Why isn't the person who designed this problem revered?

[yungmilopkl]

Australian maths be like "Oi to the power of mate², carry the roo = shrimps on the barbie."

Ye. Terrence may have had 1 out of 7..
But we have to revere the maker of the question, because he made the question AND found the answer for it.

[yashrawat]

The amazing thing is that A handful of participants were able to do it correctly in stipulated time

[t.k.-s.]

I love how this all builds up for 5.5 min, just to get more and more admiration and respect for the problem. Very much enjoyed that!

[mcol]

But why did it take 5 minutes to see the question?

[vikingslayer]

This took me 8 hours. 7 hours and 55 minutes of thinking, and 5 minutes of smashing my computer.

*Takes Simon a year to solve


Numberphile: I hope you cracked out your pencils


Me: Nah, I'm good
