(For this part, view Z as a subset of R.) Let A be a non-empty subset of Z with an upper bound in R. By the Completeness Axiom, A has a least upper bound in R, which we shall denote by m. Show that m ∈ A. (Hint: As m - 1 < m, which means that m - 1 cannot be an upper bound in R for A, we find that m - 1 < k ≤ m, or,...
