P X Q + R means P is the mother of Q and Q is the father of R.Hence R is grandchild of P.

P + Q + R means P is the father of Q and Q is the father of R.Hence R is grandchild of P.

R + Q + P means R is the father of Q andQ is the father of P.Here P is grandchild of R,but we do not know whether he is grandson or granddaughter of R.

R - Q - P means P is son of Q and Q is the son of R .Hence,Pis the grandson of R
