Directions.
  1. Review the Learning $\LaTeX{}$ document. If you have trouble finding the command for a math symbol you want to use, try looking in this Short Math Guide for $\LaTeX{}$.
  2. Get the template for this assignment (or use your own). Here’s how to do it:
    • Go to www.overleaf.com, and make sure you are logged in.
    • In a new window, go here: https://www.overleaf.com/read/vqtjypdqmmvq

  5. Submit the pdf in Canvas for the assignment Writing 03.
  6. Let me know if you have any questions!
The Proposition to Prove.

Proposition. Let $N$ be a central subgroup of $G$ (meaning that $N\le Z(G)$). If $G/N$ is cyclic, then $G$ is abelian.
