Room Keller 413
See here for the syllabus.
Announcements
 (9/23) I have been asked to pass on information to you about the Putnam exam. See here for more details.
Homework
See the syllabus for information about my grading policy for the class, and a template .tex file. Some exercises are marked as “reach exercises”. These are optional, more difficult problems. You are encouraged to attempt them, but I won’t penalize your grade if you don’t.
Please do not use blue ink for your assignments. I would like to reserve blue for grading and writing comments. If you use blue, I will be forced to switch to the angrier, more aggressive red.
