  It became a meme a few years ago, people would post problems like this and argue about whose was right, as if there were no objective truth. It hurt to watch.

    Arguably, there is no objective truth, since the symbols and rules of mathematics are assigned arbitrarily, and are basically a social contract, just like language!

    …Wait, that means there’s no objective meaning of “objective”, crap

      Well yeah take enough shrooms and everything is suddenly exposed as the artificial construct that it is. But we don’t have time to wake up and reinvent language every morning ;)

    ya this one is super unambiguously PEMDAS, the one that has more of an argument is the one with the division of whether a/bc is a / (b * c) or (a / b) * c

  In the rest of the world: yes.

  In the US: I highly doubt it.

  This is just basic math, if you can’t figure this out you’re probably 8 years old.

    Probably some backwards-ass red state / red town shenanigans.

    Math was always taught in my Blue cities. The atrocities of the US’s history was never left out of the curriculum.

    We need to actually finish doing reconstruction and fix this country.

      In all fairness, I grew up in a small town in a very red state, but the education system there proved better than larger, more progressive parts of the state. The education I received was likely an outlier and not representative of the norm, but it did teach me that educators in an area do not necessarily mirror the rest of the population.

      Fix? It’s a duster fire. It may be hard to deal with, but a total collapse and completely rebuilding it feels like the better solution to the problem (so not based on a constitution made in completely different times with muskets and without internet etc).

      So you were taught math. What languages did you learn besides English? What history did you learn, just US or also of other countries and the rest of the world? And talking about the rest of the world, how much did you learn about that? Countries, cultures, cities, geographic features like mountains, seas, etc. and how they were formed? What religions were taught about? What about history of music and art?

    I think that ordering of calculation was taught around 5th grade back in my day (11yo)

      My memory is shit, it was apparently 27 years ago if you’re right but I have no recollection to when it was. But it’s like cycling: it’s simple and once learned you never forget it.

      Now I’m learning how to weld. We’re learning Ohm’s law, which is the same as order of calculation: easy basic shit, a bit far in my memory but you never forget it. But others in my class are really struggling with it. I don’t get it.

      U = I R so R = U / I and I = U / R. P = U I so U = P / I and I = U / P. U=Volt, I=Ampère, R=Ω(Ohm), P=Watt

      This was first year in high school if I remember correctly.

      Thanks for confirming. I probably sounded too condescending but I wasn’t sure if it was a false memory.

      I loved math as a kid though, so I ran through the curriculum as fast as I could to get to the good stuff. I think having older siblings helped - it gave me a preview of more interesting material.

    Definitely taught in parts of the US, it’s a regional thing though

  In most of the world? Yes.

  We didn’t learn elements until high school tbf
