    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

        • A “teacher” who doesn’t know that all lessons are simplifications that get corrected at a higher level,

          As opposed to a Maths teacher who knows there are no corrections made at a higher level. Go ahead and look for a Maths textbook which includes one of these mysterious “corrections” that you refer to - I’ll wait 😂

          refers to children’s textbook as an infallible source of college level information

          A high school Maths textbook most certainly is an infallible source of “college level” information, given it contains the exact same rules 😂

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

          Well, that’s you! 😂 The one who quoted Wikipedia and not a Maths textbook 😂

          A “teacher” incapable of looking up information on notations of their own specialization

          You again 😂 Wikipedia isn’t a Maths textbook

            Man, this whole post has been embarrassing for you. Oof.

            I can’t help but notice youve once again failed to address prefix and postfix notations.
            And that you’ve not actually made any argument other than “nuh uh”
            Not to mention the other threads you’ve been in. Yikes.

            We can all tell you’re not a maths teacher.

            • Man, this whole post has been embarrassing for you

              Nope. I’m the only one who has backed up what they’ve said with Maths textbooks 🙄

              I can’t help but notice youve once again failed to address prefix and postfix notations.

              What is it that you want addressed?

              And that you’ve not actually made any argument other than “nuh uh”

              Backed up by Maths textbooks 🙄

              We can all tell you’re not a maths teacher

              Says person who actually isn’t a Maths teacher, hence no textbooks 😂

                Your argument you haven’t made is backed up by math textbooks you haven’t provided written for children.

                What is it that you want addressed?

                How can that specific order of operations be a law of mathematics if it only applies to infix notation, and not prefix or postfix notations? Laws of mathematics are universal across notations.

                Show me a textbook that discusses other notations and also says that order of operations is a law of mathematics.
                You don’t have it, and you also aren’t a maths teacher, or a teacher at all. Just because you say it a lot doesn’t make it true.
