Presentation: written work should be done on one side only of 8.5''x11'' paper with smooth edges. Each problem should begin a new page.
Deadlines: papers should be turned in by 2pm on the due date. Extensions may (and usually will) be granted if requested at least twenty-four hours before the due date. Late homework will not be accepted.
