We will be covering Modular Arithmetic next week, which is a continuation of this topic. If you weren’t able to make it to the Divisibility session, we highly recommend going through the handout to familiarize yourself with the basic concepts of modular arithmetic we introduced. There are also lots of extra problems in the Divisibility handout that are good for extra practice.
We hope to see everyone soon!
