WebMATH
This is a really good site, because it lets you type in a math problem that you're working on, and then it gives you a stepbystep guide on how to solve it. The site covers general math, algebra, geometry, calculus, and other stuff.

math.com
A very comprehensive site  there is help with basic math, algebra, geometry, trigonometry, calculus, and more. Again, though, be careful to follow links that are part of the site, and not other ads. Stay to the "Select Subject" menu on the left.

math2.org
A good site with some basic math reference tables. One really cool feature of this site is a math message board where you can post your specific math question, and get answers from other students and from experts.
