Beginning Proofs: Matrix Multiplication is Distributive

In this video I review the proof that matrix multiplication is distributive to review some basic ideas about proofs. If you are early on in the learning proofs phase of your mathematics career, I'd really appreciate your feedback: what made sense, what didn't make sense, and what questions you have. If you're not sure what feedback to give, please summarize an idea you took away from the video.
