  • 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.




  • 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.

    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





  • 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?
