Ok, so a long time ago in a galaxy far, far away, I went to high school. I did extremely well in Math and Science, but never really bothered much with it at the time because although I found it interesting, I was convinced I was going to change the world via politics, so focused far more on history and any class dealing with the body politic.

Time came to take my ACT's for college, and Math was my lowest score. A respectable 26, but nothing eye opening.

So I went off, majored in political science (specialization in IR), and worked for my local prosecuting attorney.

Flash forward 15 years. I've come back to something wishing I had gone a different route, and am focused on at least getting back to that entry level knowledge base that at the very least makes me feel relatively "literate".

Essentially I want to start from 9th grade level algebra and work my way up, then beyond.

So far my googling efforts haven't panned out as well as I had hoped, so I am asking you, fellow board members, for a push in the the right direction if at all possible.

I do not have the disposable income to go back to school at this juncture, else I'd just get myself reacquainted at a local community college.

Any help at all is greatly appreciated in advance.

I would check with your local high school. They may have adopted online text books. If not, try this link - http://highschool.shs.k12.ny.us/MathTexts.

In addition to Solfe's link, websites like math.com could be useful. Once you reach college level, you might want to try MIT's OpenCourseWare site, http://ocw.mit.edu/index.htm. Click on "Science" to see the math and physics courses.

So, we can more or less relearn the skills and knowledge that were lost over time?

A colleague of mine swears by Kahn Academy:

That wiki says Bill Gates uses it with his kids.

OK not really *swears*, more like enthusiastic emphasis...

Yes indeed, if sufficiently motivated. One of my fellow musicians decided to start training to be an occupational therapist and needed an entry level physics course after 20 years away from any kind of formal instruction in mathematics. I gave her some assistance in cleaning up her rusty algebra, and she went on to pass the course with flying colors.

My suggestion is "The Realm of Algebra" by Isaac Asimov. It is out of print but you can find it online as a PDF file in a number of places.

Here's one:

Thanks everyone for the awesome suggestions. I can say right now I'm having a blast at the Khan Academy. It's actually been really fun so far revisiting old concepts. I think it's due to not only the idea of learning, which I've always loved, but the fact you earn badges/points/titles as you go along. They've turned it into an interactive game, which makes it even more addicting imho.
