Kid gave a reasonable answer without all the math bullshit

With the choice of marker, I'd say its rage bait.
Can confirm. My grad mentor's grad mentor used green because he'd read a paper that green causes more eye strain and he thought it'd be hilarious to grade in green.
I grade in green because it drives my students nuts.

it’s much easier to just substract 2 from 2000, “IIMM” duh!
For anyone wondering why this is wrong, there are two reasons:
-
The roman numeral system only traditionally contains subtractions from the next higher five- and tenfold symbol. So you can subtract I from V and X, X from L and C, C from D and M
-
The subtractions only generally allowed one symbol to be subtracted, with a few notable exceptions like XIIX for 18 and XXIIX for 28
Holy shit this is dope!
But how did historians come up with the conclusion that, in the case of XIIX, the Romans substracted from the second X, and didn’t just write 12+10?
Not arguing, just extremely curious

You introduced a lie as part of the problem
There is no lie or contradiction in the problem, what are you smoking? The kid's answer is exactly correct.

The teacher didn't write OR understand the question. It's about reasonableness - that is, not just mindlessly solving math. The solution is that Marty's pizza was bigger, so 4/6 of that was more than 5/6 of Luis', smaller pizza.
There is no lie. The teached is just dumb. Or more likely overworked, but wrong nontheless.

I have an argument like that in my calculus 1 class in college, it was an optimization problem but the professor never said that the optimization variable was a constant, so you couldn't differentiate it to zero and do the normal process that you typically do. So I just wrote that given that the perimeter wasn't a constant the area to optimize goes to infinite Givin x -> inf; y -> 0, without loss of generality. He marked me zero we discussed about it and I said that I don't care because I'm going to get a 10 next test if he didn't fucked up the question. At the next exam I made some stupid error but he still gave 9/10 for the overall class because he came to accept that he wrote the question wrong and I was the only in the class actually caring and giving the class some dedication.

The general rule is that the larger symbols come first in Roman numerals, so 12+10 (22) would be written as 10+10+1+1 or XXII.
If you literally meant the arithmetic 12+10, I'd assume they used some symbol for addition, so it would be written as XII+X, but I can't say for sure.

Is there any reason at face value why the teacher’s answer is correct? From my perspective the teacher is an idiot and missing some basic math skills.
Marty ate 66% vs the other kid’s 83%, no way “marty ate more” with the information given.

This is likely a question about some topic on reasonable questions and answers, rather than a maths question.

Every time this gets reposted, everyone misses this first word.
This isn't a maths question.
It's asking the student to read the question and make an observation if it's a reasonable question and answer.
And with the information provided it's not.

I'm pretty sure the kid's answer was how it was supposed to be answered
Honestly I suspect the question was phrased poorly. It should have simply said "who ate more pizza" not stated who ate more and request to explain how

Marty's pizza is larger. 4/6ths of a 3kg pizza is more than 5/6ths of a 1kg pizza

Interesting, I'm autistic and what frustrates me here is that the question specifically asks you to posit "How is it possible" and the teacher insists that you're supposed to just say that it's not. Makes me want to just Calvinball the whole damn exam. 5 + 7, what is the answer? Purple. Obviously.
wrote on last edited by [email protected]And it’s not even some crazy stretch to make the premises work. Like if it had said the pizzas are the same size, I’d have to try to come up with something ridiculous to meet the requirements of the question, and would probably just leave it blank. But people order different sized pizzas every day.
The “correct” answer contradicts the requirements set out in the question.
Am I autistic? Or do I just have basic reading comprehension?
If the “correct” answer is valid, so is “actually neither of these people exist”, because we clearly aren’t expected (or allowed!) to accept the premises for sake of argument.

If I saw two people order different sizes of pizzas, my mind wouldn’t be blown, and nobody would consider the situation unreasonable.

I'm sorry, what? There is precisely nothing unreasonable about this question. It has a correct answer that can be found with basic logic

I've never seen so many people who are proud that they don't understand an elementary-school level math, this is hilarious.
4/6 of an extra large pizza is more pizza than 5/6 of a personal pan pizza. How are you struggling with this?

I’m not autistic but agree that the kid gave the correct answer and the teacher is wrong.
If that had happened to my kid the teacher and I would have had at least one meeting.

This kid is never going to trust teachers again.
If one bad response is enough to turn you off from anyone else teaching you anything ever, then you're carrying some enormous trauma that has nothing to do with a single math question.
If one bad response is enough to open your eyes to the fallibility of individuals and lead you to think more deeply about where you get your information and how you evaluate the correctness of a response, then you're going to go far and develop a much deeper understanding of the world.
But those things stick. I did a geography test 35 years ago and wrote Canada instead of Kanada wich which is the correct spelling in German. In the eyes of my teacher I answered the question wrong and didn't get the point, but I also got a point deducted because I did a spelling error. I didn't lose trust in teachers or society in general, but this still nags me.

I agree, the kid is correct. This is the only viable answer.
Not true. Marty could have also eaten pizza that was not his.

Yeah, most pizzerias sell many sizes. Both answers are valid.
In fact, i would argue making an assumption, in this case about size, without declaring it, is in fact less reasonable.

I can't find it now and I do not think it really applies here. But someone stated that being high IQ could lead to academic problems as the high IQ learner would understand or see things that the professor could not causing the professor to mark it as incorrect.
I guess this is the idiocracy version of it.

Or teacher didn't even see this, handed it to a high school student and said "grade this stack of papers"
I had that happen several times in science classes in 3rd-8th grade. Eventually I started arguing with the teachers in class, and boy did they not like being corrected.
Sorry Ms Avery, you not knowing that "Pb" is the abbreviation of the Latin word "plumbum", where we also get "plumbing" from due to its use in piping in rome, doesn't mean I got the answer wrong. To her credit, she looked it up and changed my grade before the end of class.
Ms hoschouli from 7th grade can get fucked though, a parallel circuit increases amperage load, not voltage load. I knew more about electronics in 7th grade than a college graduate who teaches science class, which in hindsight isn't that impressive considering it was general science and not electronics specific... But in 7th grade, as far as I was concerned I was hot shit for knowing more than the teacher, and getting detention for calling her out in the middle of class. Never got the grade changed and I only got out of detention because my parents called the school.
I had a teacher mark my answer incorrect because I said women can have hemophilia. They said you can't because it's a sex-linked disease. I said sure, but what happens if you have two X chromosomes with that gene on it? Still didn't get the point. This was in the 80s, and I couldn't just look it up on the internet and prove how wrong they were.
