    You can define your notation that way if youlike to, doesn’t change the fact that commonly f^{-1}(x) is and has been used that way forever.

    If I read this somewhere, without knowing the conventions the author uses, it’s ambiguous

      Nothing to do with me - it’s in Maths textbooks.

      Well they should all be following the rules of Maths, without needing to have that stated.

            Yeah, doesn’t mean that you know what an author is talking about when you encounter it doing actual math

            The notation is not intrinsically clear, as any human writing. Ambiguous, one may say.

                We’ve been at this point, I’m not going to explain this again. But you weren’t able to read a single sentence of a wikipedia article without me handfeeding it to you, so I guess I shouldn’t be surprised. I’m sorry for your students.

                  a single sentence of a wikipedia article without me handfeeding it to you

                  And I told you why it was wrong, which is why I read Maths textbooks and not wikipedia.

                  I’m sorry for your students

                  My students are doing good thanks

                    Apparently you can’t read either textbooks or wikipedia and understand it.

                    Also, wait, you’re just a tutor and not actually a teacher? Being wrong about some incredibly basic thing in your field is one thing, but lying about that is just disrespectful, especially since you drop that in basically every sentence.
