@@lolpop7799 you forgot about the triple factorial on "5 FACTORIAL"

@@trickytreyperfected1482 I think you could argue it's even quadruple given the written "factorial" and then the 3 exclamation points which would effectively make it 4 factorials

I mean, I could do it in my head between the buzz in and countdown. But I also used my fingers...

That’s a trick my friend uses at math competitions. You buzz in instantly and solve the problem while they acknowledge you

It’s a trick in Quizbowl, history bowl, and Certamen. Sometimes, you gotta buzz first and then think fast. Of course this should only be done in your speciality ie. Classical history or biochemistry or literature etc.

@@Sentient_Blob yeah whenever i am at team competitions like that i always buzz in first but it is also because i have someone else to back me up but i think the kid just underestimated the complexity of the question

@@Wasteman365 his comment says nothing about him improving in math or not. He's saying that the pressure of the show would make it harder to answer the questions

The only right answer

Great answer, but I'm sure the sticklers at Jeopardy would only accept 120.

Kyle Home they’ve accepted technically correct answers like that before

It's not really correct because that would be the same as just repeating "What is 1*2*3*4*5"

@@BiffGreggle Thank you Sean.

they're* I had to correct it sorry

for the 600 dollar one, they should;ve said 5!

It’s that they didn’t have enough time to do the mental math in time.

I’m sure they could’ve solved those equations, they just needed more time then you get to answer on Jeopardy

How about the fact that common core doesn’t help kids

weird flex

Weird flex indeed. You’re still a baby

@@gabe8168 I know lol. That’s why I was kinda surprised by the weird flex comments lmao.

Lol

Any adult could, but it’s not shocking that a kid can’t

Anyone who has spent a little bit of time improving their arithmetic operational efficiency should be fine.

Don’t say that not anyone can do it. That’s wishful thinking on your part. When I was in middle school I took part in a similar competition. I can say from experience that you’re correct about the stress and time pressure. However, a child was asked what something like 58^2 - 56^2 was and he answered correctly almost immediately. It was well within the time limit that these kids had for this game of Jeopardy. To say that no one can do it is absolutely untrue.

@@zurreal8087 He probably did difference of squares and then it’s just multiplication, probably the simplest way to do that problem in your head. 58^2 - 56^2 = 2*114

QuadLamb031275 Yes, you're correct. He both recognized to do that and performed the calculation in a few seconds. My point more than stands.

Which was the really confusing part considering trebek literally gave them the answer a second before.

They definitely are. They're a bit above these kids' grade levels, though.

If they weren't prepared for Jeopardy that's on them.

@@AT-il2ej Regular Jeopardy typically doesn’t have mathematics categories like this because they realize doing quick mental calculation of anything more than two numerals is so outside the genre of the show that the category becomes a lead weight that gets avoided until the rest of the board is cleared, like with this category’s last two clues.

I don't think many people are bragging about their own ability or ragging on the kids. I think most of the comments are just lamenting the fact that they haven't received the same training people used to, where problems like these used to be common speed exercises in elementary school.

@@innertuber4049 pretty sure at least most of them are joking about how petty it is to feel good about beating kids at solving math problems

+rcspence They did the 1X2X3X4X5 question at the beginning of the game and the -1 X 2 X -3 X 4 X -5 question at the end of the game, so you would not expect them to remember, would you?

Michael Ryan -1 × 2 × -3 × 4 × -5 = -120, not 120

Richard S, no. Because you’re multiplying 24 by -5. Adding a negative number to a positive number will make it negative. Two negatives negate each other. The answer is -120.

@Davis Wilson What do you mean?

@Davis Wilson : I believe that's exactly what Gary said. (Or at least implied.) Or maybe you were intending to reply to Richard S?

I just did 9 - 6

It doesn't matter what order you add or subtract them, one way to think of it is that you're adding all of them together, except some are negative. I personally worked backwards, starting with positive 5, adding negative 4, etc.., which kept me on the positive side of zero, which made it simpler for me to not have to keep track of whether my running total was positive or negative.

There's not necessarily a best way. I took on the negative numbers first, saw they gave -6, which would cancel with the 1+5, leaving only the 3.

Left to right

I did (1+2+3+4+5) - 2(2+4) = 15 - 12

Funny thing about that equation - with the alternating signs, it forms a pattern. At each step, the answers are 1 (obviously), -1, 2, -2, and 3. (Subtracting 6 would then get you -3, and so on.) That’s how I learned to do it quickly, because yes, it seems very simple but can throw your brain for an absolute loop.

You realize it's the same as -6 + 9? That really shouldn't be difficult.

@@toaster4693 the problem is the time pressure, and that you have to be the first to buzz in.

They had ages.. how was that hard?

@Flyin' Steve oof, boring. rounded to how many digits?

I’m guessing a multiplication problem but they didn’t have time for it

You are correct, but "common core math" as a term refers to the current standard of teaching math by picture. It claims to make kids understand math instead of just memorizing it. The fail on the last question proves that they absolutely do not understand math AND they haven't memorized it. Twenty years ago, all three kids would have had the answers before Alex finished reading.

Call it what you want, but these are the brightest kids out there, and they couldn't answer 3 of these simple math questions. Common Core is a failure, in that it fails to teach kids real math.

@@TimCarter: Once again, it's a list of content standards. It can't succeed or fail at anything.

@@adde9506 "The fail on the last question proves that they absolutely do not understand math" How? I could understand why you would come to that conclusion if they had done the $800 clue right after the $400 clue. But this video was edited just to show this single category. Looking at the board, they did 23 clues (and contestant interviews) between them!

@@TimCarter Nowhere in the real world is quick calculation of problems like the latter clues needed or asked for; you’re given more than 5 seconds to come up with the answer. There’s also a reason math problems are uncommon in the ADULT version of Jeopardy, as well: it’s a memorized trivia competition, not a math bee.

Nope

We got a badass over here folks.

Valid strategy. Buzz in then think fast

@@Carnage7209 Particularly for a category you solve rather than know.

They weren't actually asked right in a row, though. Thinking back to another question you were asked several minutes ago in five seconds is a lot. Faster to solve it again.

I got 1x1 up to 12x12. Luckily I don’t see a ton that’s purely multiples of 13-20

What, you only learned from 1x1 to 20x20. We had to memorize up to 99x99 (obv 100x100 is easy) in 4th grade.

I think that's why the category is called "Non Common Core Math". They just don't teach that stuff anymore.

@@bowlchamps37 that's about 4950 +-10 numbers to remember, why would you say that lol Edit: more like +- 200 at least and 1000 at best but the point stands

And as a kid I never actually memorized them. I just learned to solve them mentally quickly enough my teacher didn't notice.

Don’t know why but I think it’s funny to imagine the comment “would have accepted 5” but excited instead of factorial

@@comrendu why not be exited that it’s factorial?

You’re so cool

Yeah but those kids were idiots

Pemdad?

I think he means PEMDAS. But this is correct.

No, using PEMDAS you don't arbitrarily swap the subtraction and addition signs. Also, these are all addition/subtraction, so the order of operations doesn't come into it. You didn't understand PEMDAS.

@@Enaronia Doesn't PEMDAS apply to all equations? Even if it is only addition and subtraction?

@@Sir_Charles1558 If there's only one type of operation, then... sure I guess, but it doesn't do anything. PEMDAS absolutely doesn't stand for "randomly reassign all the signs." You could get any number of different answers doing that. You can add the numbers up in any order--that's the commutative property of addition--but you have to add up *those* numbers and not different ones.

That's how the Jeopardy game works. The clues are supposedly answers, and you have to come up with the questions. Although they're really obtuse answers if you take that literally. "What is three?" "1-2+3-4+5." What kind of answer is that?

@@Enaroniayeah exactly. I don’t understand people who ask that question because everybody who is a jeopardy fan knows how it works. You always say what is before your answer and in double jeopardy you would be penalized if you don’t say it.

they are being trained for common core math tho

Just imagine the pressure though...

I’m almost 30 and I couldn’t do a couple of those in the time required.

@@FlackNCoke 1×2×3×4×5 was 120. -1×2×-3×4×-5 should therefore be obvious. Just count the negatives and depending on whether there were an even or odd amount, just answer it as 120/-12]

@@anonymousperson3023 They didn't take that question until a lot later in the game, however (notice the board between the third and fourth question). So while it is obvious to us edited back-to-back, they may've forgotten the prior answer by that point.

Adults who throw tantrums at the words "Common Core" tend to have really bad basic math skills.

He probably thought he'd just figure it out while he was in the clock. Makes sense.

I could see myself doing that than having my mind go blank tbh

That's how you play Jeopardy. You always press the buzzer, and hope you can rack your brain and find the right answer in time. Checking with yourself to ensure you have the answer hurts your reaction time

Scout He thought if I buzzed in and made sure he got the right to answer he could figure it out in that time, rather than let someone else buzz in before he finished calculating.

Because he's an idiot.

I'd say it's because he gets A's in math and was confident that he could compute the answer, but the kids are not learning real math in school today.

@@TimCarter I'm sure you also didn't learn real math in school when you were in school either.

@@TimCarter when was the last time you sat in on a math class to see what they were learning?

Being able to do arithmetic in your head is not important whatsoever past elementary school.

@When you BOTTOM TEXT explain.

@@Baconator1368 : Actually, it is. I do it every day. But I would agree that it's not necessarily important to be able to do it in five seconds!

@@Milesco My point is that if you have a calculator on hand you would have no reason to do it in your head. This is especially true considering basically everyone always has a calculator on hand (their phone).

@@Baconator1368 : Yeah, that's true, but I find that it's sometimes easier and quicker to do a relatively simple math problem in my head than to fish my phone out of my pocket, swipe the screen, enter the password, swipe again to start the calculator app, and *_then_* begin to actually enter the numbers and do the computation.
