Elementary Number Theory

On Friday when you hand in your homework, you can put it through the slot in the door of the graduate student mail room on the second floor (Krieger 209). However, be sure and put the grader's name on your homework, i.e. put "to Shengwen Wang" on it.

The grader, Shengwen Wang, will be in the help room (Krieger 213) every Friday from 9am to 11am. You can give your homework directly to him there if you want.

On the problem set, there are 3 points per problem. You have to have it all right to get all 3 points. A little bit wrong and you get 2 points. A little bit right and you get 1 point. All wrong is 0.

If there are parts to a problem with labels like (a), (b), and (c), then each one of these is worth 3 points.

If the answer is in the back of the book for a problem, you need to make sure that you show your work or prove your result, something you actually have to do for all the problems anyway. This is particularly true for computational problems.

Due to a revised policy in the course, only 10 of the above problems will be graded, but you don't know which ones, so best to work them all.

Note that this week there are only 10 problems though.
