Q restricted rewrite system:
The TRS R consists of the following rules:

   plus(0, x) -> x
   plus(s(x), y) -> s(plus(x, y))
   times(0, y) -> 0
   times(s(x), y) -> plus(y, times(x, y))
   p(s(x)) -> x
   p(0) -> 0
   minus(x, 0) -> x
   minus(0, x) -> 0
   minus(x, s(y)) -> p(minus(x, y))
   isZero(0) -> true
   isZero(s(x)) -> false
