That reminds me of my College Algebra professor from a couple semesters ago. He liked long tedious computations. There were plenty of times I'd stop in his office hours, and he'd just be sitting around doing math. I was a little bit more passionate about math than any of the other students in my class, and he always ended up giving me some extra problems to do when I stopped in his office hours. Not for extra credit or anything, just to challenge me and see if I could work them out. Some of them were quite difficult, given the nature of the course. He was one of the coolest professors I've ever had.
Have fun in that class; differential topology is literally the coolest thing ever.
