Hello, this is my first post. Anyway, when I was in high school I did not have my priorities in order so I missed out on my math education. About a year ago or more, I started reading a brief history of time. Now today I have read all the hawking books as well as several that covered specifically relativity, Quantum mechanics, String theory, M-theory etc. I have grown to love these subjects and I need to relearn basic math in order to go on to the complex math stuff so I can truly understand the subject. Is there a site or book that can dumb down the basics again so I can get a thorough refresher and move on to the really complex stuff? I am considering this as a degree choice and although I am good at math I forgot all the formulas and I am out of practice in general.
