Symbolic series is what the user often encounters first when looking in Sage for power series. They are somewhat limited with respect to Sage's PowerSeries and LaurentSeries. You see you cannot do arithmetics at all with symbolic series:
sage: s = SR(1/(1-x)).series(x,5); s 1 + 1*x + 1*x^2 + 1*x^3 + 1*x^4 + Order(x^5) sage: 2*s 2*(1 + 1*x + 1*x^2 + 1*x^3 + 1*x^4 + Order(x^5)) Realistic behaviour must be added on Pynac level, it's simply not there at the moment, if I understand correctly. For that reason it would be helpful if someone could at least review those tickets that deal with symbolic<-->dedicated ring conversion (#10846 <http://trac.sagemath.org/ticket/10846>, #16203 <http://trac.sagemath.org/ticket/16203>, #17402 <http://trac.sagemath.org/ticket/17402> and maybe #17400 <http://trac.sagemath.org/ticket/17400> and #17659 <http://trac.sagemath.org/ticket/17659>).
