Prompt

Make a roadmap with the best resources to learn CS + Mathematics + Economics on my own from zero (I know it is kinda weird roadmap with all those subjects but I love them all equal). I tend to prefer books over courses or videos. Divide it into: Fundamentals, Undergraduate, Undergraduate electives, Graduate, Graduate electives and "Other readings" for books and readings that are not central to the progression but worthwhile. Divide resources between essential or suplementary.
