MAYBE

Problem:
 strict:
  minus(x,0()) -> x
  minus(s(x),s(y)) -> minus(x,y)
  quot(0(),s(y)) -> 0()
  quot(s(x),s(y)) -> s(quot(minus(x,y),s(y)))
  plus(0(),y) -> y
  plus(s(x),y) -> s(plus(x,y))
  plus(minus(x,s(0())),minus(y,s(s(z)))) -> plus(minus(y,s(s(z))),minus(x,s(0())))
 weak:
  rand(x) -> x
  rand(x) -> rand(s(x))
