      even if they were paid well, which they absolutely should be, that wouldnt make the pool of teachers necessarily smarter at this kind of math. the issue is that most math teachers are just regular teachers that arent necessarily checked well for math competency. for instance, my middle school science teacher actually specialized in social studies, but was forced to teach science because of the shortage.

    In the Netherlands, the schools were required to move to "realistic calculation" in their testing and teaching, which broadly meant no longer asking "6 x 7 = ?" but "Martin drinks 6 glasses of water every day. How many glasses does he drink in a 7 day week?" This was supposed to make it easier and more practical for students, who'd get to deal with realistic situations instead of abstract math.
    When this change was made, you got a lot of angry parents, when the "realistic" story the teachers had to quickly make up for every problem would not be worded carefully enough to get the 6 x 7 = ? that the teachers actually wanted to hear.
    One question that made the rounds was something like "It takes 7 minutes to boil and egg, how long does it take to boil 6 eggs." The kids who answered 7, because in a realistic scenario you'd put 6 eggs in the pan together, got their answers rejected. The teacher wanted to test if the kids could calculate 6 x 7 = 42, but they didn't specify that the eggs would be cooked one at a time.

    • @Freedom-of-Thought

      No, even in one pan it takes longer boiling 7 eggs than boiling one, because of the thickness and the specific heat capacity.

    I had a teacher like that in Junior High. She taught US History. We were covering the Civil War era. A question on a test was "Who assassinated Abraham Lincoln ?" I of course wrote "John Wilkes Booth" My test came back with my answer marked wrong. When I asked why, she said because I spelled Booth wrong, It was spelled "Boothe" Mind you, my answer wasn't marked "-1 point for spelling", it was marked completely wrong. So, I walked over the the bookshelf, grabbed a dictionary and flipped it open to "Booth (no "e"), John Wilkes":, and showed her. Her response: "That's how I spelled it in class, that's how you have to spell it". Some time a year later I was sitting in a study hall, and noticed that in the History notes the guy next to me was studying he had written: "Monoplane: An airplane with one engine" (reference to the Spirit of St Louis) being an airplane enthusiast from a young age, this caught my attention, and I pointed out to him that was not correct, that a "monoplane" was an airplane with one set of wings, as opposed to a "Biplane" with two sets of wings, not a single engine airplane. He rolled his eyes and said, Yeah, I know, but that's what Mrs. Dumais (Same person as My previous year's History teacher) told us, so that's what we have to answer on a test. And we wonder why people have become disenchanted with public schools.

      Another answer would be a loophole in the bad English of this question. The word “his” is used twice and the first one clearly refers to Marty’s pizza, whereas the second “his” could refer to Marty’s pizza or Luis’s pizza. So you could take a guess that Luis actually ate 5/6 of Marty’s remaining 2/6 of pizza. Assuming Marty’s pizza was a full pizza when he started eating it, that would mean Luis actually ate 5/18 of a full pizza which is less than 4/6.

    The real issue here is that the teacher doesn't understand what the point of the question is. This question is asked specifically to highlight one very important point about fractions: fractions can only be compared if they are fractions of the same size group or object. That is the fact that is being taught there. It is useless to compare 3/4 of this pizza with 3/5 of that pizza if the pizzas are not the same size. When we teach fractions at school, we often teach them mostly in an abstract sense where we just assume the object or group that the fraction is taken from is always the same as every other one. In concrete situations, this cannot be assumed.

    Reminds me how in 6th grade, our first semester math teacher gave us a bonus problem on a math quiz: Given a pie, how many equal slices can you make with exactly 3 straight cuts? The answer she wanted was 8: you make two cuts to slice it into quarters, then stack the quarters on top of each other and slice down the middle to make 8. Not everyone got it, but that was okay, it was just a bonus question. You could still get a perfect score even if you got it wrong.
    Our second semester math teacher gave us the same bonus problem on one of her quizzes: given a cake, how many equal slices can you make with exactly 3 straight cuts? As we had knew the trick from the first semester, everyone put 8. The teacher informed us the next day that every single one of us was wrong... because, according to her, "you can't stack cake like you can stack pie." On top of that, she gave everyone -1 on their final score for answering incorrectly, and since the quiz was out of 10, that was basically a full letter grade drop. (Admittedly on a quiz which contributed very little to your final grade.)

      I...I'm sorry, 'cake can't be stacked like pie'? PIE can't be stacked! Cake is *constantly* being stacked, you'd be hard pressed to buy a cake that *isn't* at least two layers with some cream in the center. Besides which you don't even *need* to stack the cake, you can cut it in quarters then slice horizontally through the center of the cake. Any pie I've seen is either a crumbly uneven crust or an open crustless top, and you're more likely to have pie slices moosh and tilt and slide all over each other than you are to have cake do that. I guess we're assuming the *pie* defies physics to allow the stacked cut, so the cake is *also* defying physics to *not* allow the cut? I'm...unreasonably angry at this story of yours. I've *never* heard of stacking pie but I was willing to accept it because it's a logic problem not an actual baking challenge. But the very idea that you can't stack *cake* ...even Donkey from *Shrek* knew cakes have layers! 'Can't stack cake'...that's going to be echoing around my head all day. What the hell.

So there is a difference between how far you "could" see and how far you actually "can" see. The question was how far you could see, that is, under optimal conditions, with nothing obstructing your view, you having superhuman vision, what is the farthest you could ever see.

    When I was in high school I had an English teacher that was a real piece of work. She could not grasp the concept of percentages. I spent an hour after school one day trying to explain it to her but it was like talking to a wall. Her guide book said that 94 was needed for an "A" and 69 to pass & she could accept that for one test but if she gave 10 tests per semester, instead of 940 for an "A" & 690 to pass she just added 900 so you had to score 994 for an "A" and 969 just to pass. I embarrassed her in front of her class many times so I expected her to fail me, which I wouldn't have accepted, but she gave me a "C" that should have been an "A" & I took it & moved on. She made us read stories and we had to know about the authors, so this one guy from Scotland wrote about this "bonny" lady that had everything that she needed but was never satisfied. The teacher had never heard of the word "bonny" and thought that it was "bony" & changed the whole meaning of the story. saying "the poor woman always wanted more because she was bony & couldn't afford to feed her kids". I couldn't help but laugh out loud at her & so she made me read the definition of the word "bonny" in front of the whole class.

      I personally perceive this question not as “Non-percentage wise, who ate a greater quantity of pizza”,this kid would be correct, but percentage wise, you could reason that perhaps Luis had less slices of pizza, which would make his pizza with less slices not smaller, but still equal to 100% of the pizza even if it is missing a few slices, that’s still his perception of 100% of the pizza. Marty, may have all his pizza slices, thus that’s 100% of his pizza allowing HIM to eat more because his 100% isn’t larger, it’s the same size just with more slices.. maybe I’m crazy but idk.

      FF (Foreign Friend): “How old was the chicken 🐓?”
      Since the kid was confused by this, I suggested she just say: “I don’t know? Tell me why?”
      She became irritated 😠 as in: “How can I answer the question if I don’t have all the facts?”
      I had a feeling this was going to take a long, long time !! ⏰.
      So … by consensus we finally agreed the chicken was female, and about 3 years old. It was a White chicken 🐓. It was about noon 🕛 and slightly overcast. It was a country road, unsealed with very little traffic …
      You get the general idea. And this seemed to take forever as in: “It’s a joke …!”
      FF: “It may be a joke to you, but not the chicken 🐓.”
      And, on it went ….
      30 years later my friends still talk about “why did the chicken 🐓 cross the road?”

    Why are we assuming that the pizzas are round and that we measure the size difference in diameter. You can just use a nominal unit (mass or volume) of any size. And then make Luis's size a nominal size of 1. You don't even need to use units
    Then you have two equations:
    Luis: (5/6) × 1 = 5/6
    Marty: (4/6) x Y = 5/6
    You don't really even need the Luis equation except for understanding the idea of the Marty equation. You solve for Y in the Marty equation:
    Y = (5×6)/(4×6)= 1.25
    So, it needs to be 25% bigger. It's fine that this differs from the Diameter answer because neither mass nor volume have a proportional relationship with diameter. They're different calculations entirely. One is a length, the others - mass or volume, however you are calculating what "more" is. The best way to calculate this would have been the simple calculations, and then backing into diameter if you like.

      My thought exactly. You simply need to have (4/6) x Y > (5/6) which is Y > 1.25

      I had to scroll way too far to find this answer. It particularly irked me when Presh says that the pizza must be 11.8% bigger. No, it must have a 11.8% greater diameter because you assumed a circle. The correct answer is the one you gave, 25%, which is true for any shape and also accounts for thickness. Its also a much easier calculation.

      It doesn't matter what shape the pizzas are (including any irregular shape), provided the two pizzas are the *same* shape that have simply been scaled by the same amount in width and height (i.e. maintaining the aspect ratio). This is about understanding dimensionality relationships under scaling.
      For *any* consistent linear measurement L (e.g. the diameter, radius or circumference for a circle, or with a rectangular pizza maybe height, width or diagonal) on the shape, the area of the shape will always be proportional to L^2. Therefore if the area is 25% bigger the width, length, diagonal etc will be sqrt(1.25), i.e. 11.8% bigger.
      Here we're scaling in two dimensions, so the volume and mass are also proportional to the area. If instead we were scaling in three dimensions (i.e. the pizza got thicker as it got wider and taller) then the volume and mass would be consistently proportional to L^3. So if we were thinking of bigger in terms of weight, then 25% bigger in mass (and volume) would be 7.7% bigger (cube root) in linear dimensions - width, height diagonal etc.
      Another example: think about a small penguin, and an identically shaped big penguin. If the big penguin's flipper length was 2x that of the small penguin, other 1-d relationships would also scale by 2x - its beak-length, feet-length and the circumference around its belly, would also be 2x bigger than the small penguin. 2-d relationships, such as the total surface area of its skin, or the area of its feet would be 4x bigger. 3-d relationships, like the volume of its blood, mass of its heart would be 8x bigger (assuming all of the anatomy has been scaled identically!).

    Maybe the teacher was somehow expecting the student to answer "This is not possible", but the question was badly worded, instead of saying for example, "Marty thinks he ate more than Luis. Is he correct? Why?", it said that Marty ate more than Luis as if it was a fact that the student could not deny.
