    A multiple choice question where all the answers are wrong, says nothing about math or the mathematical understanding of the general population.

    This is engagementbait and its hooked you too.

    It’s not a bad analogy for american democracy. None of the options are correct, so you either pick the wrong answer that makes some amount of sense or write in the correct answer and be completely ignored in the tally of results.

    This is why I write it as 2+(2x4). The parentheses aren’t techniclly necessary, but they do make it clearer to people who haven’t been in a school for 35 years.

      Order of operations only has one rule: Bedmas (or pemdas if you’re not from north america)

        Huh it was always pemdas in both highschool and college in new England for me… they were also always parentheses. ‘Brackets’ only reffered to ‘[ ]’ which were reserved for matrices or number sets, eg 2*[2,5,8]+2= [6,12,18]

        If you look at the arguments on math forums, you’ll see that there isn’t just one rule.

        It is a convention, and different places teach different conventions.
        Namely, some places say that PEDMAS is a very strict order. Other places say that it is PE D|M A|S, where D and M are the same level and order is left-to-right, and same with addition vs subtraction.
        And others, even in this post, say it’s PEMDAS, which I have heard before.

        “Correct” and “incorrect” don’t apply to conventions, it’s simply a matter of if the people talking agree on the convention to use. And there are clearly at least three that highly educated people use and can’t agree on.

    I know this is a PEMDAS joke, one of many for the PEMDAS throne.

    But yeah, we need to really, really worry about the coming day when “math becomes a democracy” and that is already happening for a wide array of other facts and knowledge about the world.

    Whatever “civility politics” liberals infested our collective minds with have to be abandoned. We have to get a lot harder and a lot less tolerant of other people’s “beliefs” even if you think “Well they’re only harming themselves by thinking 1x1=4” but they’re not, we need to start viewing these people as threats to our future. We no longer live in isolation, whatever bullshit your parents drove into you about “nothing on the internet being real and shouldn’t matter” was utter hogwash and even less relevant in 2025/2026. We get everything from the internet, including a sense of community and connection, which is why nutsoids find each other and turn something like a joke about earth being flat into an entire anti-science movement.

    If you’ve ever seen those dumb sci-fi shows or movies where science if forbidden and people caught learning science are punished, and thought “that’s so unrealistic” well I have some real bad news for you.

    Should really allow people to answer how they want.

    Who’s Big Math in charge of the multiple choice?

    Who’s denying a voice to those who want to answer that question with “10”? [Edit: or “F”? ~ or an essay on being “off by 1”]
