I found it few days ago by accident. What a surprise!
This site is the best one I've came across so far. It covers from grade one to advanced mathematics, i.e. Calculus.

I used to be good at math... I'll check it out!

Thanks you for sharing this website hughe. Mathematics has never been my strong suit but I recognize its importance and have always enjoyed self-learning. I'm already signed up. :)

Pencil, lots of papers.

If you are serious about studying math, I suggest get two powerful tools on hand.
The first tool is a scientific calculator. Graphic calculator is overkill, get a simple scientific calculator under $30.
Mine is Casio fx-991MS. It's been running on original battery over nine years.

Once your math subject gets advanced, average time of solving calculation would increase.
Because number of steps that derive solution of the problem increases.
This is the right time to learn CAS (Computer Algebra System) software. I mostly use Sympy, CAS library for python.
Maxima is Open Source CAS software (http://maxima.sourceforge.net/).

Mathematica (http://www.wolfram.com) is a must if you really want go down the rabbit hole in math.

However, MS Excel can be used with minimal training to quickly solve 95%+ of the problems most folks run into in their daily lives. I call it a "poor man's" programming environment.

However, I will vouch that Kahn is probably the best structured way to learn math on your own. Frankly it's better than 95% of the math classes you'll ever take as:

1) it's free
2) the concepts have been broken down into understandable chunks with excellent diagrams
3) its interactive.
