@imabuddha@techhub.social Indeed. Fortunately, I did better on the remaining problems in the section.

I've had similar frustrations with art books for "the absolute beginner".

I'm sure some of my computer science students are baffled by what I think are clear, straightforward explanations of concepts. (Indeed, student evaluations from any class will have some complaining that I moved way too fast and others wondering why I wasted so much time on the obvious.)

The interesting topic is fire dancing. When I show initial moves to new students, they can't understand how I move so fast. By the time they graduate, they're better than me. In my defense, I'm old.
