Problem:
 a__and(tt(),X) -> mark(X)
 a__plus(N,0()) -> mark(N)
 a__plus(N,s(M)) -> s(a__plus(mark(N),mark(M)))
 a__x(N,0()) -> 0()
 a__x(N,s(M)) -> a__plus(a__x(mark(N),mark(M)),mark(N))
 mark(and(X1,X2)) -> a__and(mark(X1),X2)
 mark(plus(X1,X2)) -> a__plus(mark(X1),mark(X2))
 mark(x(X1,X2)) -> a__x(mark(X1),mark(X2))
 mark(tt()) -> tt()
 mark(0()) -> 0()
 mark(s(X)) -> s(mark(X))
 a__and(X1,X2) -> and(X1,X2)
 a__plus(X1,X2) -> plus(X1,X2)
 a__x(X1,X2) -> x(X1,X2)
