Typical math undergrads study real numbers (real analysis), complex numbers (complex analysis), integers (number theory), structure(abstract algebra), linear maps & vector spaces(linear algebra), continuity(topology), discrete structures and systems (discrete math/analysis), counting (combinatorics), chance(probability) etc Knowing how to program makes learning computer science that much more enjoyable. Similarly, coming into mathematical theory with a decent grasp of how math proofs work makes for a smooth(ish) journey through the math landscape. That said, consider the following FREE book that can introduce you to math from close to zero: Book of Proof by Richard Hammack. https://www.people.vcu.edu/~rhammack/BookOfProof/ https://www.people.vcu.edu/~rhammack/BookOfProof/
