> I found math professors to be the worst instructors I encountered, without a doubt Same. If this weren't common I think memes like "this is left as exercise to the reader" wouldn't exist. I'm convinced most of them find math intuitive to a point where they can't indentify at all with people who struggle with it and have no idea where to even start explaining things. And it also takes patience to try and bridge that gap. Not to mention a lot of maths concepts depend on understanding other ones and education in general just assumes that each person is proficient in everything from previous classes. It's similar with technology as well, some people know immediately how to rule out problems or google a solution while others struggle to come up with the right question.
