Let F be an ordered field with the least upper bound property. Prove that there is a unique function o : Q → QF that satisfies the following properties: o(p q) = 0(p) · ở(q), $(p +q) = ¢(p) + ¢(q), if p < q then ø(p) < ¢(q) %3D for any p, q E Q. Hint: When constructing o, work your way up from N, to Z, and then to Q.
