There are several.  Maxima and yacal come to my mind.  The wikipedia
article at http://en.wikipedia.org/wiki/Computer_algebra_system has a
list of propietary and open source algebra systems.  I can't really
say if they are very good, since I haven't used them seriously, but
i.e. when I took a glance at maxima, it seemed quite powerful.
