Can anyone recommend a good course of mathematics study for an adult with almost negligible knowledge? Is Khan Academy the best place to start?

  Khan Academy is great, but only covers through high school / engineering university math, last I checked. Having a good grasp of that is helpful, but if you want to learn real math you'll need to branch out. It depends a lot on what you want to get out of it. If you want to get actually well-versed in mathematics (say, undergrad math major level), you'll need real and complex analysis, linear and abstract algebra, naive set theory and formal logic, and it couldn't hurt to get some topology and geometry in there as well. On the other hand if you just want a particular subject (say graph theory), the prereq list will be much shorter. Or if you just want a general competency, just learning naive set theory and formal logic will get you to the point of at least being able to read the notation used. So again, really depends on what you want out of it. I'm happy to provide specific advice re books etc if you do end up deciding to start studying. edit for clarity: If what you want is just HS math competency (trig, HS algebra, calculus) then Khan Academy is definitely the way to go, in my opinion.
