# Stony Brook MathCamp 2022

## July 18-22

Each day from 9-5, there will be a session running for the classes, which will remain active when classes are not in session. Think of this as the "classroom" where the classes will take place, but also where you can talk to other students or instructors between/before/after classes. The link to the session is
