Times listed are in EST. Assignments are released on Tuesdays, and are due 6:00pm on Mondays. Clicking on the Overleaf Template link will open a new Overleaf project, so you can write your homework solutions in LaTeX.

Recitation sections are held from Wednesday to Sunday. Also, if you need to miss a recitation and need to request an absence, fill out the form here.

How do hours work?

CS22 hours are collaborative spaces for students to work together on problems, facilitated by TAs. Hours will be primarily in-person. More details about hours can be found in the Course Missive.

Here is a link to the course calendar (same as below).

Course Textbook

Discrete Mathematics and Its Applications — Kenneth Rosen

Reading this textbook is not required, though many students in the past have found it helpful in reinforcing what's covered in lecture!

Exam 2 Resources

The exam review guide is meant to give an overview of the content covered in the relevant sections and some extra practice problems. It is not a substitute for studying the homeworks, recitations, and lectures!

LaTeX Resources

LaTeX (pronounced *la-tek*) is a program that you will be using to make your homework solutions look beautiful. LaTeX allows you to incorporate mathematical notation into your proofs, and because this class involves a healthy dose of mathematical notation, LaTeX is going to be very useful! Using LaTeX is required after the 2nd homework.

We don't expect you've ever done this whole LaTeX business before, and that's why we're giving you some time to learn it! To get started, we recommend creating an account on Overleaf, an online program for writing and compiling LaTeX. After you do that, here are some links to check out: Honestly, please use Overleaf. It's so much easier than installing anything on your computer. Trust me.

• CS22 LaTeX Cheat Sheet (start here!)
• A Not So Short Introduction to LaTeX
• LaTeX Symbols Guide
• Art of Problem Solving: LaTeX
• LaTeX Intro Wikibook
• LaTeX on Brown CS Systems
• LaTeX Gearup Template
• LaTeX Gearup Completed Handout

In general, a really good resource for learning LaTeX is the web. When you have a question, google it, and you'll likely find someone who had the very same question!

If you'd like to download LaTeX on your computer, here are some resources to do that:

• MiKTeX (Windows)
• MacTeX (Mac)
• Texmaker (Cross Platform)

If you're using LaTeX and you just don't know what the code for some symbol is, here is a helpful list to start:

Common LaTeX symbols

Alternatively, this is a neat site which will return the LaTeX code based on handwritten input (although searching your question on the web is likely more efficient):
