Is there a online reference that chains mathematical knowledge from simple to complex?

Question

I'm a very, very logical person -- but I've never taken any math classes; really, I know.

So, on that note -- how do I teach myself math? As my question might suggest, I see the answer as being an online reference that chains mathematical knowledge from simple to complex -- but I'm open to other suggestions. One thing that would be of interest is if the resource had a rating on the complexity/depth of knowledge required to reach an understanding of the given concept; yes, unlikely, but doesn't hurt to ask.

Questions, feedback, comments -- just comment, thanks!!

Answer 1

Learning maths is like building, all foundations must be down before the next level. So the first question you need to answer well is: "What do I understand already?" (note the use of understand, not know)

Once you know where you are at, then you can find the next level up, if your level is under that taught in regular schools you should be able to identify your level roughly by grade (probably per domain: number, geometry, etc.) and move up from there. If you are already up to a degree level, then finding a natural path ahead is more subjective matter, there is much to cover but many routes.

Perhaps expand your question with your current opinion of your level to get more accurate help.

Answer 2

I think the exercises at Khan Academy may be useful. They have exercises in mathematics ranging from basic arithmetic to advanced calculus that gradually build your way up, as well as lectures and practice questions to help check your progress.
