For Math resources, there may not be a more powerful tool than Wolfram Alpha. Check out the Math examples. For many problems, Wolfram Alpha will show you the answer, the steps it took to get that answer as well as graph the answer for you and show you all kinds of other relevant data.

Wolfram Alpha requires that equations are entered in a particular way. For example, the polynomial: x3+x2y+xy2+y3 must be entered as x^3 + x^2 y + x y^2 + y^3. It takes a little practice to learn how to use, but once you do it can be better than a calculator in many ways.
