Question 458167: What is the best free algebra app?

I use Wolfram Alpha, which is a free, no-download computing engine similar to that of Wolfram Mathematica software.

You can type in something like "solve x^3 + 6x + 4 = 0" and it will find all zeros. Or, you could search other things, for example, the GDP of Belarus, or the fraction of people in the U.S. named "John."
