I believe you missed one: Maxima.

http://maxima.sourceforge.net/

It is ultimately descended from MACSYMA, which is the most venerable
of all computer algebra systems, and from what I can see it's
definitely not abandoned (considering that the last official release
was in 2005). I've used it and it's probably the closest Free
alternative to Mathematica or Maple.
