2. If P + Q means P is the father of Q, P - Q means P is the wife of Q, and P x Q means P is the brother of Q, what does A - B + C x D mean about A and D?

   A is D's mother. A - B: A is B's wife. B + C: B is C's father. C x D: C is D's brother, so D is also B's child. Since A is B's wife, A is the mother of D.
