Oh, WOW. Two weeks of durr?-inducing Math just clicked. The action of clicking actually hurt my brain, like some kind of metal part snapped. But yay, stuff makes sense now! Except the last two problems of the homework, which make sense, but I just have no idea how to solve them. :D

I think that when a TA has to cancel office hours, she should have to find someone to take her place. Just a thought.
