A few years ago, I was teaching a class and decided to record a short series on the fundamentals of mathematics, for complete "beginners" - whether they be kids or adults. This is the first video in the series Thinking Mathematically (after the introductory video, "Why think Mathematically?") which I put on YouTube under a channel of the same name. It proceeds through the sets of numbers, N -> Z -> Q -> R -> C and yes it's for beginners. Would love some feedback: https://www.youtube.com/watch?v=Wd1lzqR3xW0 https://www.youtube.com/watch?v=Wd1lzqR3xW0 The other videos you'll find on that channel are: 1. Why think mathematically? 2. Numbers and Algebra 3. Sets and Infinity 4. Logic and Probability Here is the channel with all the videos. They might be useful to share with people who you want to understand these concepts from the ground up: https://www.youtube.com/channel/UCuge8p-oYsKSU0rDMy7jJlA https://www.youtube.com/channel/UCuge8p-oYsKSU0rDMy7jJlA (PS: I am generalizing this approach in our upcoming app, https://teaching.app https://teaching.app)
