In the structure presented below, letters P, Q, R, S, T, U, V, W and X take natural numbers 1 to 9, with each letter taking a different numberP   Q   RS   T   UV   W  XP x Q x R = P x S x V = R x U x XR + U + X > P + S + VS x T x U is odd

For some integer n, the odd integer is represented in the form of:
