My question is more hypothetical than practical: what would an ideal solution look like? I literally have no idea.

Promotion from associate professor to professor is not automatic; indeed, there are several associate professors in my department who have been at that rank for some time, and seem unlikely to get promoted. But it is reasonably common, unli

Since you seem knowledgeable about the topic, could I ask -- What would an ideal solution look like? Say I have a complicated equation. How could I present it (in any format) so that a blind person could read it, and understand it as easily

I would say this is true of a programming language, but not really of LaTeX. Now LaTeX technically is a programming language, it's Turing complete. But in practice for most users it's not. Sure, there might be subtle inconsistenci

As a frequent LaTeX editor (professional mathematician) -- what are you attempting to accomplish? And what do you mean by a "best practice"? My usual operandi is: poke around or Google for a solution, until I figure out one of the

I never said it was easy. In fact, in some sense, the problem is much harder than you might realize at first. This particular rabbit hole goes down very deep. I am not urging this family of problem on all high school students. Rather, on

I'm a math professor, a white male, I was something of a child prodigy, and I was enormously blessed with math coaches who went far out of their way to help me. I agree wholeheartedly that opportunities need to be made more available

This works because of generating functions : You can check that 1/(1 - x - x^2) = 1 + x + 2 x^2 + 3 x^3 + 5 x^4 + 8 x^5 + 13 x^6 + 21 x^7 + ... To check this (not totally rigorously), multiply both sides by 1 - x - x^2 and multiply ev

As a math professor, I'd recommend contacting this professor, mentioning that you're going to take the class, and asking them. Along the lines of todd8's advice, you might ask for advice on how to best prepare. These are the
