If you just want to learn math for purely practical reasons, Khan Academy (http://www.khanacademy.org) is great. It might have added more lessons, but when I went through it, it went up through 1st year college calculus.
The thing that makes it VASTLY better than most self study math programs or books is that there are hundreds of exercises that you can do, and see if you got the right answer. If you didn't, it will in most cases explain how to do the problem so you can try again with a completely different problem, so you're not just memorizing the answers.
Another thing that makes it great is you can do a little bit a day, start and stop, and come back to it and it will remember your progress and where you left off.
Khan is also a gifted teacher. Unlike a lot of math teachers, he has great pronunciation and handwriting and you can watch his lessons as many times as needed.
They don't have exercise for some of the more advanced college level topics. You can see the exercises on the right side of the screen under "practice" for some of the more introductory topics:
