Problem Set 1

I spent most of the week trying to find Problem Set 1 posted on the website after I read that it was due on Friday. Unfortunately, I didn't find it until this morning despite several searches on the website that returned up nothing. Now I'm getting random posts with the words 'problem' and 'set' in them, including the one about the problem set being posted. Obviously, the bulletin board system and I don't get along.

Lucky for me, the problem set was only two questions long. The first question was about the unit digit of 4^(n), very similar to the example of 3^(n) given in class. The second question was a simple induction question about the number of pairs in a set of numbers {1, 2, ..., n}. I was also lucky enough to have a light bulb go off in my head during the officer hours today. I hope the light bulb goes off again later when I'm trying to do Assignment 1.
