  That’s not even an equation, just basic algebra

    Fair enough, I’ve heard “math problem” and “math equation” used interchangeably.

    Also you would be surprised how many people do not know basic algebra, at least in the US rofl

      You. You are one of them bc you do not know what an equation is.

      There is no algebra here. This is arithmetic.

    Algebra has horrible syntax. Way too much implications.

  While I never failed a math class, I also never went last high school. When would your presumptions NOT be true?

    Some forms of programming syntax, although there are the fringe cases where an equation is represented by a symbol in conjunction with a parentheses input.

    For example:

    y(x) = 2x+3

    5+y(1) = 10, as 1 is substituted in for x in the prior equation.

      And in some languages a number can be used as a name of a variable or a function, so it can be anything really

  I prefer BM-DAS, no one’s out here doing exponents, and no one calls brackets “parentheses”…

    The way I was taught growing up, brackets are [these]. Parenthesis are (these).

    Yes, technically the latter are also brackets. But they can also be called parenthesis, whereas the former is exclusively a bracket. So we were taught to call them separate words to differentiate while doing equations.

      I’m a theoretical physics grad student and a night school maths teacher, I have never heard this distinction. People in academia around me call them round and square brackets.

        It’s a US vs UK (and probably others) distinction. The ( ) are almost never called brackets in the US, unless it’s a regional thing I’m not aware of. Also the [ ] didn’t get used in any math classes I was in the US up through calculus except for matrices.

      Yeah, but as an adult it depends entirely on whether you’re in an industry or hobby that requires that level of bracket nuance/exponents.

      Most of us are just trying to remember the basics.

    I learnt it as BODMAS (brackets, orders, division and multiplication, addition and subtraction).
