Math 350, Section 01, Spring 2026
Rob Benedetto


All section numbers are from Saracino, Abstract Algebra, a First Course, 2nd edition.

Videos may be found on the Math-350-01 moodle site.

This table will grow as the semester progresses and more problem sets are assigned.

All sets due on Gradescope at 11:59pm ET on their due dates.

(Think of that as 11:49pm, allowing at least 10 minutes to submit on Gradescope and assign pages to problems.)
