An Example of a Torsion Module

Showing that $\frac{\mathbb{R}[x]}{\langle x \rangle}$ and $\frac{\mathbb{R}[x]}{\langle x-1 \rangle}$ are not isomorphic as $\mathbb{R}[x]$ modules.

Corollary of the Malgrange Preparation Theorem

Every $\mathbb{Z}/6\mathbb{Z}$-module is projective

If $A\cong B$, then $A\otimes C\cong B\otimes C$.
