If you are solving Problem M of HW N, please submit the solution as a PDF file called ringsNpM.pdf. Your writeup should include the assignment number, the problem number, the problem statement, and the names of the group members. Each problem solution should be submitted as its own document, not one document containing several problem solutions. After receiving your solution I will act as the referee on your submission. This means that I will check it for clarity and correctness, and I will correspond with you about improvements. This step in the process should take at most one week. You are not obligated to take any of my advice, but if one of my comments involves a correction, then you should correct that part in some way. (For example, if I say "Here is a shorter way to do it", you don't have to change anything unless you want to. If I say "The first displayed equation is wrong. Here is how to fix it …", then you should fix the error, not necessarily along the lines of my suggestion.)

New assignments will be posted every other week starting the second week. Solutions to old assignments will be posted when they are in final form. You should read your classmates' solutions.
