    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.

        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]

    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”]

    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.

    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.

      13 is probably the next most chosen because it’s closest to 10.

      Not including the correct answer is also a form of engagement bait to get additional comments and such saying “wait the real answer is 10, wtf?”

      Your obviously is only a convention and not everyone agree with that. Not even all peogramming languages or calculators.

      If you wanted obviously, it would have to have different order or parentheses or both. Of course everything in math is convention but I mean more obvious.

      2+2*4 is obvious with PEDMAS, but hardy obvious to common people

      2+(2*4) is more obvious to common people

      2*4+2 is even more obvious to people not good with math. I would say this is the preferred form.

      (2*4)+2 doesn’t really add more to it, it just emphasises it more, but unnecessarily.

        common people who are not good at math…

        PEMDAS is in the 5th-grade curriculum.

        My obviously is gated to people who can hadle 5th-grade math.

        I would say we should not provide the mathematically illiterate any say in the matter. They need to spend 10 minutes on Youtube and learn it.

      • PEMDAS isn’t obvious to “common people”? Why not? It doesn’t seem like an arbitrary convention to me…

        If “×” means “groups of,” then “2+2×4” means “two plus two groups of four” which only makes sense, to me, to be read as “two plus two groups of four” rather than “two plus two groups of four”

        Sure the order of operations could be arbitrarily different, but I feel like we settled on that order because it simply makes more sense intuitively.

        I’m aware of the possibility that it only feels natural and intuitive to me because I was taught that way, but I at least don’t think that applies to this specific example

          PEMDAS isn’t obvious to “common people”? Why not?

          Clearly not if most of these answers are incorrect. If it was obvious, there wouldn’t be as many answers as there are.

        Honestly that’s my pet peeve about this category of content. Over the years I’ve seen (at least) hundreds of these check-out-how-bad-at-math-everyone-is posts and it’s nearly always order of operations related. Apparently, a bunch of people forgot (or just never learned) PEMDAS.

        Now, having an agreed-upon convention absolutely matters for arriving at expected computational outcomes, but we call it a convention for a reason: it’s not a “correct” vs “incorrect” principle of mathematics. It’s just a rule we agreed upon to allow consistent results.

        So any good math educator will be clear on this. If you know the PEMDAS convention already, that’s good, since it’s by far the most common today. But if you don’t yet, don’t worry. It doesn’t mean you’re too dumb to math. With a bit of practice, you won’t even have to remember the acronym.

          Most actual math people never have to think about pemdas here because no one would ever write a problem like this. The trick here is “when was the last time I saw an X to mean multiplication” so I would already be off about it

          1 + 1/2 in my brain is clearly 1.5, but 1+1÷2 doesn’t even register in my brain properly.

            Right, and that clue IMO unravels the more troubling aspect of why this content spreads so quickly:

            It’s deliberately aimed at people with a rudimentary math education who can be made to feel far superior to others who, in spite of having roughly the same level of proficiency, are missing/forgetting a single fact that has a disproportionate effect on the result they expect.

            That is, it’s blue-dress-level contentious engagement bait for anyone with low math skills, whether or not they remember PEMDAS.

        I feel like people should at least remember math at a 4th grade level and be able to get 10. What is the point of making it obvious the universe will never ever arrange itself in such a fashion. The point is if you remember simple rules you applied for a 10-15 years.

        There’s just 5 lots of 2. If it’s hard then think of x being just a bunch of + smooshed together. So

        2 + 2 x 4

        expands to

        2 + 2 + 2 + 2 + 2

        or contracts to

        5 x 2

          You’ve completely not understood that order of operations is an arbitrary convention. How did you decide to expand the definition of multiplication before evaluating the addition? Convention.

          You can’t write 2 + 2 ÷ 2 like this, so how are you gonna decide whether to decide to divide or add first?
