Prove Proposition. In other words, show that if az is a real number and n an integer, then (a) [x]<n if and only if a <n, (b) n< [a] if and only if n < x, (c) n< [a] if and only if n < x, (d) [a]<n if and only if a <n. As a cautionary tale, find counterexamples to each of the following state- ments: (e) [x] <n if and only if a <n, (f) n< [a] if and only if n < x, (g) n< [a] if and only if n ≤ a, (h) [a]<n if and only if a <n. The moral of the story is that you need to be very careful when you omit floor or ceiling functions in integer comparisons. Prove Proposition.
