    Wikipedia

    In mathematics and computer programming, the order of operations is a collection of conventions about which arithmetic operations to perform first in order to evaluate a given mathematical expression

    What’s that? You don’t trust Wikipedia?
    Ok, you’ve yet to explain why notations like prefix and postfix dont need these “rules”.
    If they were rules of mathematics **itself** how could they only apply to certain notations?

    • Wikipedia

      isn’t a Maths textbook 🙄 far out, did you learn English from Wikipedia too? You sure seem to have trouble understanding the words Maths textbook

      You don’t trust Wikipedia?

      The site that you just quoted which is proven wrong by Maths textbooks, THAT Wikipedia?? 🤣🤣🤣

      you’ve yet to explain why notations like prefix and postfix dont need these “rules”.

      Umm, they do need the rules! 😂

      how could they only apply to certain notations?

      They don’t, they apply to all notations 🙄

        I love how confident you are about something you clearly have no knowledge of.
        Adorable.

        Well, you made a good effort. At least if we’re judging by word count.

            To a “maths teacher”

            Yeah sure
            A “teacher” who doesn’t know that all lessons are simplifications that get corrected at a higher level, and confidentiality refers to children’s textbook as an infallible source of college level information.

            A “teacher” incapable of differentiating between rules of a convention and the laws of mathematics.

            A “teacher” incapable of looking up information on notations of their own specialization, and synthesizing it into coherent response.

            Uh huh, sounds totally legit
