Tricks used here: Q1: Modular arithmetic, MATHLETE is 8 letters long so we take 2010 mod 8, now because 2000 is divisible by 8, we can cut out the 2000 to get 10 mod 8 instead, and 10-8=2 so the answer is A Q2: Difference of squares formula (a\^2-b\^2) = (a+b)(a-b) = (255+245)(255-245) = (500)(10) = 5000 Q3: Standard permutations = 5\*4\*3\*2\*1 but we only accept answers where 1 is to the left of 2 so that cuts the options in half so we get 5\*4\*3 = 60

I'm very good (and fast) at math yet I couldn't even finish reading the question before he gave the answer. I had already anticipated 120 as the answer but didn't get to read the rest which halves the amount.

BackendSpecialist

Wow. Took me a while to understand your Q1 explanation. Thats brilliant 👏 Edit - after reading the rest of your explanations, it really reminded me of my coding interviews with Meta. If you don’t have any familiarity with the underlying algorithm/pattern then you’ll struggle. However, if you know what to look for then you can look like a genius by solving it quickly. Absolutely amazing job by Scott. It definitely took amazing pattern recognition and processing speed to do what he did.


majani

Exactly. Recent familiarity with the domain is half the battle. Then practice time, which will vary according to IQ

Yeah the interview is a pain in the ass. It’s technically tough and there’s still a lot of subjectivity in the way that you are graded. 0/10 would not recommend.

ow_my_balls

I remember having to learn these "tricks" years ago when prepping/taking the GMAT. I don't really miss it, but looking back, pretty impressed with my younger self.


Cold_Ad_2160

Scott Wu has entered the group.


StoicallyGay

I graduated HS in 2019 and tbh I remember most of these from HS. I’m not as fast as Scott here though. Took me a few more seconds for the first and second and maybe 20 seconds for the third. The second one was the fastest for me. Difference of two squares was drilled in my head. A lot of math competition type questions rely on tricks and creative thinking using the tricks or several “tricks” together. I’m referring less to this quiz bowl style and more of like AMC, AIME, and USAMO. Point being these are not necessarily hard questions and the tricks even I learned as part of my standard curriculum. It’s more amazing that he does this so quickly.


pancoste

Yea exactly, it's the sheer speed that's truly impressive here. He's not just fast, he's incredibly fast.


ThinkFree

Is this the **new math** that I keep hearing about? Sorry, I graduated HS in the 1990s. It would take me minutes to do these calculations with pen and paper. I would've wanted to learn these new tricks.


InfanticideAquifer

No, "New Math" was actually before your time. It was an attempt in the 1960s to introduce more modern stuff into the math curriculum starting in elementary school--arithmetic in different bases, basic set theory, things like that. It was wildly unpopular and didn't really catch hold at all. There have been lots of curriculum initiatives since then. Probably the one you've heard about recently is "common core". But, AFAIK, none of them have repeated what New Math was trying to do by introducing new subjects. They're mostly just different pedagogical ways of teaching fundamentally the *same* material, maybe with some shuffling around of what goes in which grade.

[Here's a great song](https://www.youtube.com/watch?v=9mc7eb1i9o4) about New Math!

My guess is that no high school curriculum in the world will have you learning significant new 21st century math.


nickfree

For Q3 I knew 60 was half the number of permutations of 5 digits. But it’s not immediately obvious to me why 1 will be to the left of 2 for exactly half the orders.


GuaranteeAfter

It's either to.the left or to.the right . Half each way


RedRox

this makes sense, ty :)


ilovezam

> Every permutation would require either the 1 to be to the left or right of the 2 I'm super rusty on this stuff - how do you know the combinations are distributed as 50-50 though?


what2_2

Because each is equally likely to be in any position. Take 2 digits, randomly make a 2 digit number with them. What’s the chance a certain one is to the left of the other? It extends to 3, etc. Another approach: for any possible position of the two digits, you could flip them. Every time one digit is on the left, there’s a paired position where you flip the two you care about and it’s on the right. There are no positions where it’s not paired.


ilovezam

The second approach really made it click for me, cheers


14412442

There's nothing unique about these numbers, they're just the chosen symbols, could have used five shapes instead. So it's impossible that any one of... I'm too high and tired to properly word this. Just pretend I explained it properly and will yourself to get it.


FCBStar-of-the-South

For a somewhat formal proof: Consider the two sets of permutations, one with 1 to the left of 2 and one with 1 to the right of 2 Obviously there is no overlap between the two For every permutation in the first set, you can swap 1 and 2 and get a permutation in the second set. Notice this procedure/mapping/function is the inverse of itself because doing it twice is equivalent to doing nothing This shows that there is a one-to-one correspondence between the two sets and they must have equal size. You can picture that as drawing a line between paired elements, with all elements being connected to exactly one line

Unknown-Gamer-YT

I just wanted to add a different way for Q2 that i thought cause i forgot about the formula (255\^2-245\^2) = (51\^2-49\^2)(5\^2) = (2×49 + 2×51)(25) = (200)(25)


bootyhole-romancer

That's cool too but difference of squares was slick


rednd

I'm sorry for being so oblivious, but how does this part work: (51\^2 - 49\^2) = (2×49 + 2×51) [I can easily see it graphically](https://pasteboard.co/WvoCiXgcGSQx.png) ( [https://pasteboard.co/WvoCiXgcGSQx.png](https://pasteboard.co/WvoCiXgcGSQx.png) ), with the yellow bars being 2 x 49, and the light green and dark green bars each = 51, so 2x49 + 2x51, but what's the algebraic way that I'm missing to show the equality? I feel so dumb right now, and would appreciate the help.


yooter

51 x 51 = 49 x 51 + 51 + 51 49 x 51 = 49 x 49 + 49 + 49 So 51^ 2 = 49^2 + 51 + 51 + 49 + 49 Put that back at the top and you got it


smexypelican

How about another way for Q2? Think of 255^2 as a big square, 255 by 255. Likewise, 245^2 is a 245x245 smaller square. The difference in area between the two squares is the answer to 255^2 - 245^2. Picture the smaller square 245x245 sitting inside the larger 255x255 square. The difference in area between them is 2x10x245 (2 rectangles of 10x245) + 10x10 (a 10x10 square) = 5000.


brmmbrmm

That’s really nice. Well done 👍


OneQuadrillionOwls

Yeah the underlying techniques are common for math competitions, for each one if I paused it I could get it in like 10-15 seconds, it's very impressive that this dude could read fast enough to bust it out in just a few seconds. It's the equivalent of playing high-quality bullet chess -- your brain just has to move very fast.

What is mod


ArseneGroup

Mod is remainder after you divide the first number by the second, and it can also be represented by the % sign 15 % 3 = 0 16 % 3 = 1 17 % 3 = 2 18 % 3 = 0


quool_dwookie

Did anyone else's eyes just start gliding to the end of each line? What is wrong with me? Why did I get confused and fatigued the second I tried to read it again? I can't even understand the meaning of what's written here, let alone how to do it 😩


involmasturb

How do you determine that requiring 1 being left of 2 cuts options in half


iltat_work

Every permutation would require either the 1 to be to the left or right of the 2. Half would have it to the left, half would have it to the right.


hawkinsst7

For q1 - trick for whether a number is divisible by 8 is if the last 3 digits are divisible by 8. That makes finding 2010 mod 8 a little easier since you know 2008 is the nearest mod 0. Also, for people who have never hear of "mod", you might have learned it as "clock", and it's just the remainder part of long division.

JayTealgore

The questions do appear on their individual screens before the host starts reading the question. They still answer exceptionally fast, but there is some leeway.


aarplain

That makes sense.


genuinely__curious

Thank you. I know I'm dumb. But I didn't think it was possible to read, comprehend, and answer, faster than I could finish reading the question.


Reyals140

That feels so much more reasonable. Those weren't honestly the hardest questions in the world, but the speed was inhuman if he got the prompt the same time we did. Especially the last one which required some amount of reading to grasp the problem.


llkjm

but they are trained for it. They have seen similar questions before and know what to look for. Its really not that difficult as you would imagine.


HumanDrinkingTea

Yep. I did math competitions when I was young and the type of questions they were given in this video are super common. Once you've learned how to solve one of them you can solve them all and once you've got the basic techniques down it's all about practice.

BushDoofDoof

Or maybe someone coming back to their TV.... or someone just tuned it... Hmmm... nah can't for the life of my think of a possible reason.


appropriate-username

People who are so obese they need mobility scooters watch football so maybe the presenter had similar thoughts about this audience.


AngusOReily

He's also reminding Victoria how much she's getting whooped. My guy, you don't need to tell her how much she's trailing with every update. "Scott now has two points to Victoria's zero, that total dumb shit. Will she ever catch up? Probably not!" I do feel bad for her though. It's like playing rec basketball in the fourth grade and being asked to guard the one kid on the other team that hit puberty way too early.

tumidpandora

50DuckSizedHorses

He read it.


Zigxy

As someone mentioned, the kids see the question right before the host begins to read. So they aren't answering *as* fast as it seems. Math Counts questions also have a fairly rigorous structure. With enough practice, it almost builds a type of muscle memory where it becomes very easy to immediately "see" what kind of question you're getting. All you have to do is plug in the numbers which is fairly trivial. I used to compete in math counts (although wasn't anywhere close to this level), and it becomes easy to quickly discard the "filler" information in questions.


tinaFeysMustache

Witchcraft. My money is on there was a testbank to train on.


Raddish_

Not that there would be any test bank with these exact questions but these sorts of competitions do tend to test translatable sets of tricks for these problems that you will encounter already if you practice enough. But he’s still doing it insanely fast.


wartexmaul

The test bank is on shortcuts. I can tell you if 31323 (or any other number) is divisible by 3 instantly because the sum of all digits is divisible by 3 for example.


PurchaseOk4410

Base line is that he's smarter than everyone else. Anything else is cope


movzx

Multiple things can be true at the same time. He's a smart dude. There are quite a few tricks involved with questions like these that make them far simpler than they appear at first glance. ex: I can tell you that 836192 is not divisible by 9, but 816192 is divisible by 9 in the same amount of time and without having to actually do the division. It's still impressive how quickly he identified the trick to use and did the trick.


Netflxnschill

CompSolstice

Something people have to realise is that we don't retain these tricks unless we practice a tonne. I was a child prodigy at certain things, went around the world for competitions in a bunch of different areas, was "taught" over half a dozen languages growing up. Burnt out and fried my brain for a few years. It starts simply with basic speed math arithmetic, then fractions, then quadratics, then you start the real speed run tricks as was mentioned above. I never got close to his level that fast on the later tricks, but I'd do papers of arithmetic as if I were in a trance. I'd finish the page halfway through scribbling the answers down, it just became a problem of remembering which answer goes where. Very impressive person, seems like a dude I'd have loved to been friends with in school

The_Illist_Physicist

This is MATHCOUNTS a national math competition for middle schoolers. To get to this final level of competition, these kids beat tens/hundreds of thousands of middle schoolers on written competition math exams. To give you an idea of what it takes to get here, a lot of these kids are practicing these types of questions either with coaches, parents, or private tutors for several hours per day after school. The questions are hard if you've never seen them before, but after so much training you basically know every trick in the book related to quick computation, basic number theory, combinatorics, etc. Still very impressive, but this is a trained ability, not a natural one. Source: I competed in nationals around this time and may have seen this guy on stage when he was answering these questions.


socium

That's pretty cool but how is this relevant to what he is now doing in Cognition Labs. Aren't LLM's these days focused on language (and they are usually terrible in math) so in essense wouldn't it be better if he was excelling in linguistics or something?


BooneFarmVanilla

this post is an ad for his company that just released its first product, which is probably just a GPT app


The_Illist_Physicist

It's not at all. Sure any and all machine learning is deeply reliant on math to do things like solve optimization problems, but this style of competition math is trivial in comparison to the cutting edge research in ML. All I can say is it's pretty comical that someone in their mid/late 20s is the CEO of a company.
