Proper Subsets vs Improper Subsets | Set Theory

What is a subset in math? What is the difference between a proper subset and an improper subset? In this video, we will answer those questions so you know exactly what improper and proper subsets are, as well as how to write about them. In the video I describe writing a subset sign as a C, however it is more accurate to describe it as a capital U on its side, thanks to Greg Adams in the comments for that improved description. I hope you find this video helpful, and be sure to ask any questions down in the comments! ◉Textbooks I Like◉ Graph Theory: https://amzn.to/3JHQtZj Real Analysis: https://amzn.to/3CMdgjI Proofs and Set Theory: https://amzn.to/367VBXP (available for free online) Statistics: https://amzn.to/3tsaEER Abstract Algebra: https://amzn.to/3IjoZaO Discrete Math: https://amzn.to/3qfhoUn Number Theory: https://amzn.to/3JqpOQd Related Videos: An Introduction to Sets:    • An Introduction to Sets (Set Theory)   What is a Union?:    • What is a Union? (Set Theory)   What is a Subset?:    • What is a Subset?   ◆ Donate on PayPal: https://www.paypal.me/wrathofmath ◆ Support Wrath of Math on Patreon:   / wrathofmathlessons
