Proof Writing Workshop Fall 2021

Go back to Home Page

If you're taking your first proof-based math course or just want to improve your proof-writing skills, sign up for our Introduction to Proofs workshop!

Learning how to write proofs takes time and practice, and this workshop is a great opportunity to get more familiar with how to go about writing proofs. The lessons will have a mix of lectures and exercises to try in small groups with help of the TAs, so you'll get lots of practice and constructive advice. We'll give an overview of mathematical logic, different types of proofs, and discuss good mathematical practices that'll help you succeed and get the most out of your classes.

Please sign up by filling out the Intro to Proofs form. By completing this form you will be added to an email list through which you will receive more details. If you have any questions feel free to contact Anda Tenie at ast2175@columbia.edu.

Undergraduate Lecturers and TAs: Elena Gribelyuk, Cassandra Marcussen, Destine Lee, Ruoxi Li, Leo Lo, Iris Rosenblum-Sellers, Carson Teitler, Anda Tenie, Alan Zhao, Jacob Weinstein
