  • so 5 literally cannot be a function if that’s the case

    No, but it can be and is a coefficient of the Term 5(8-5)

  • Depends on the language

    No it doesn't

  • 5 isn’t a valid function name, is obviously the right answer.

    5 is a coefficient of the Term 5(8-5) is the correct answer

  • insist mathematics has exactly one perfect unambiguous syntax,

    It sure does! 😂

    2*(1+3) is somehow different from 2(1+3)

    Yep, one is Multiplication - 2x3 - the other is The Distributive Law - (2x1+2x3) - both easily found in Maths textbooks

    Nope! The Distributive Law

  • If kids where taught how to solve them properly we wouldn’t need to dumb down equasions

    They are taught how to solve them properly. It's only adults who've forgotten the rules of Maths who get them wrong

  • an implied multiplication

    There's no such thing. It's a Term/Product.

    is the normal thing you learn in (I think?) somewhere between 5th to 7th grade

    Yes, you learn that it's a Term/Product in Year 7

    You only add an operator if it’s something else

    You never add an operator, or you end up with wrong answers.

  • I thought math was relatively universal

    It is

    The US education system may be different

    They have the same rules, but they don't require Maths teachers to have a Maths qualification (in Australia you have to have a Masters), and they have been sliding in world rankings for more than a decade.

  • I live in Australia and don’t recall my school at all teaching me this in maths class

    I'm in Australia, and I remember being taught it, and I teach it.

    people exist that live in other countries and every countries education system is different

    The rules are the same everywhere, only the notation varies (in Germany they use . for multiply and : for divide, and say "dot before slash", slash being - and +).

  • What? A number next to parenthesis always means multiplication

    No, it means distribution, a(b+c)=(ab+ac)

    Are people really not taught this anymore?

    They're taught distribution yes. It's only adults who've forgotten the rules of Maths who get these wrong

  • Google implied multiplication

    There's no such thing. It's a Term/Product. Google is a prime source of Maths disinformation (yes, they have been told it's wrong, repeatedly, so it's disinformation).

    Do you write 2x or do you write 2 • x?

    2a=(2xa) by definition, and 5(8-5)=(5x8-5x5).

    That’s implied multiplication

    No, that's a Term/Product.

    Implied multiplication

    Terms/Products

  • Put a goddamn function sign for the parenthesis

    Why?

    Don’t assume everyone just knows what to do with the parenthesis alone

    Well, everyone was taught what to do with it in high school.

  • Brackets and Orders, not that anybody calls “(” a bracket or “^” an “order”.

    It's "to the order of" actually. 2² is 2 to the order of 2

    not that anybody calls “(” a bracket

    Yes we do. They're ALL Brackets - square, round, squiggly...

  • Why do people put bot pairs of multiplication and division, and addition and subtraction on the acronym?

    Because it's intended to be used as a checklist

    Do you really follow that order with the associative operations?

    Yep

  • BODMAS (or BEDMAS), not BOMDAS. (unless they did that in some random state). I'm an Australian Maths teacher

  • multiplication and division are the same operation

    No they're not, but they are both binary operators.

    in order to stop confusing people, it should just be: BOMA.

    Leaving out D and S confuses people about where to do them in the order. It's intended to be used as a checklist

  • Was anyone else ever taught it as BOMDAS as opposed to BODMAS?

    I don't think so, and I've seen Maths textbooks from all over the world. Only the U.S. wants to reverse the order of DM from everyone else's acronym. 🙄
