I like the selection of topics and the resources recommended, but I'd love to see some recommendations of "front the ground up" resources, like start with ELI5 stuff like variables, math operations, expressions, equations, functions, notation conventions, etc. In my experience as a tutor, many people have gaps in their "basic math" knowledge, so it makes learning pure math topics more difficult to access (like if you don't know what the symbols are, you can't see the beauty of the thing). I've been working on addressing this problem through my books (links in profile), because I think it's important to consider the general audience, which means including all the "high school math prerequisites in each book. For anyone who is wondering how to fill in these basics skills, the khan academy videos + interactive exercises are probably the best way to go: https://www.khanacademy.org/ https://www.khanacademy.org/ If you prefer a book on the topic, check mine: https://nobsmath.com https://nobsmath.com Here is the concept map from the book that lists the various topics normally covered in high school math that I think everyone should know: https://minireference.com/static/conceptmaps/math_concepts.pdf https://minireference.com/static/conceptmaps/math_concepts.p...
