I'm having difficulty with my math, fractions and up. I used to understand it all, but it's been so long since I've touched the book (I finished it a couple of months ago, picked it up to review everything), I seem to have forgotten it.
The explanations inside of the individual chapters do no good. They never helped me, and I always resorted to having my older brother helping (who is now away at college), and I can't find any resources online that help at all.
Are there any online tutorials / guides that can help me relearn all this fully, all the way from the basics, up to college level?
