seems I'm a few weeks late as per usual with /leftypol/'s current activity, but as an actual PhD(c) applied math I'm compelled to post anyway. also the two serious recs here are hilariously bad or unfit
I would brush up on basic knowledge of algebra and trigonometry/geometry, basically HS math or what you might see as "pre-calculus" or "pre-algebra" in college syllabi. Then if you're majoring in a math-heavy subject you'll want to learn calculus, linear algebra, maybe discrete math, maybe probability and statistics.
Regarding sources I'll recommend Paul's Online Math Notes and Prof. Leonard's lectures:
https://tutorial.math.lamar.eduhttps://www.youtube.com/@ProfessorLeonard/coursesAnother decent resource for very basic stuff is Khan Academy if you like their format. Also check out the OSSU repo, which is mostly a list of links to relevant online courses:
https://github.com/ossu/math>>25852>I want to major in a math subject for my bachelorsWhat motivates you about math? Do you specifically want to major in math (or applied math) or do you mean another STEM major, perhaps CS or some kind of engineering?
