Problem 5. Let a, b, c E Z. Decide which of the following statements are true and which are false. For the true ones provide a proof, for the false ones give a counterexample. Here a, b, and c are integers. (1) If c b and c|a - b then ca. (2) If a b then bla. (3) If a be then a b or a c. (4) If ac and bc then abc. (5) If a b+c then a b or ac.
