Best way to teach myself math from the ground up?

[Swirly]

Hi all

I'm a few successful CLEPs into my journey and while I love the social sciences and history, math is...shall we say, not my strong suit. I'm eager to learn, though! Although my goal is to just be able to pass one of the math CLEPs (any one - just need 3 math credits) - I really do want to *learn* the material and master math for its own sake. I'm basically looking to teach myself from the ground up here, and I'm not sure where to start. Does anyone know of a solid resource to start with the basics (ahem, basic beginners algebra or similar skill level) that explains things in a clear way and progresses up through more difficult material? The less money involved the better, but I'm definitely willing to spend a small amount to master this if necessary. Thank you in advance for any suggestions
