401R3.3 Inequalities, Absolute value, and Triangle Inequality

[@mike_the_tutor1166]

You're an amazing teacher. I've been watching your videos for three years now. I watched all the videos in your group theory and undergrad knot theory playlists. I'm an autodidact so it's been great having university level explanations outside of reading a textbook. Thank you for your work. Two years ago I started a website, the goal being to index all the math videos on KZbin. If you want the link, just ask.
