Termination w.r.t. Q of the following Term Rewriting System could be proven:
Q restricted rewrite system:
The TRS R consists of the following rules:
sum(0) → 0
sum(s(x)) → +(sum(x), s(x))
+(x, 0) → x
+(x, s(y)) → s(+(x, y))
Q is empty.

We use [23] with the following order to prove termination.
Recursive Path Order [2].
Precedence:
sum1 > 0 > s1
sum1 > +2 > s1
