Hello frens,
I did an economics meme degree about 2 years ago, and the most math I have ever done in a course had to do with basic calculus, linear algebra and basic least-squares regressions.
Since last year I have gotten an interest in computer programming, and I'm finding that I'm very often facing a roadblock in my projects because of a lack of a strong mathematical foundation. I can only go so far until I need to basically copy and paste some dude's work from Stack Overflow.

I considered seriously learning math through a combination of YouTube lectures, textbooks and problems. I can't afford college right now so this is the best I have. Is it possible to teach my-self this way?

I think what I would like to start with is the basics, so I picked up a typical year 1 course list for a math degree (includes number theory, foundations, group theory, etc.) and will be going through that. Any advice you guys can give me?
Much appreciated and thank you.
