What math you need is not clear. High-school algebra at least. However the pace, poor explanations, ambiguous code requirements, and a total lack of support makes this course incredibly difficult if you have no experience with algorithms at all. It really feels like an algorithms refresher course. This is not a good course for beginners.

Not much of an intro - he goes way too fast & you need a LOT MORE than high school algebra for this!
