Math 3400 / Lgic 2100 Fall 2022 Masking Policy

While you are not required to wear masks in other university buildings, I ask that everyone continue to wear masks in our classroom DRL 3C4 in class Math 3400 / Lgic 2100. I know that masks might feel awkward, but I also know that wearing masks plays a role in showing respect for each others' health and comfort.
