SAGE is a free software project that has some of the capabilities of tools like Maple, Matlab, Mathematica MathCAD etc.
There's an online notebook that you can use freely in order to share stuff:

I also downloaded the Windows VM, which can be found here:

Linux and MAC variants available too, as is all of the source.
