I wish someone would put together the "basic math" resource for people like that. I didn't do any maths beyond 16. I was an maths idiot at school (me? the teacher? I dunno) but since then I've worked 20 years in programming and had to learn more and more maths just to make a living. However, my maths is a rickety hodge-podge house, with no real foundations. I can't be a total idiot, because I've done some decent work in distributed systems, even research in CRDTs (which made me learn some math) but still, I'd love a self-study plan that took me from 16 to today with the _real basics_.
Thanks for your comment, it made me feel less alone.
