 TRS:
  zero(sharp()) -> sharp()
  plusAC(x,sharp()) -> x
  plusAC(zero(x),zero(y)) -> zero(plusAC(x,y))
  plusAC(zero(x),one(y)) -> one(plusAC(x,y))
  plusAC(one(x),one(y)) -> zero(plusAC(x,plusAC(y,one(sharp()))))
  multAC(x,sharp()) -> sharp()
  multAC(zero(x),y) -> zero(multAC(x,y))
  multAC(one(x),y) -> plusAC(zero(multAC(x,y)),y)
