    * From a proposition, its inverse, its converse and its contrapositive are derived as follows: *: Proposition: "If P then Q." *: Inverse: "If not P then not Q." *: Converse: "If Q then P." *: Contrapositive: "If not Q then not P." * If a proposition is true then its contrapositive is, too. Thus, if the statement "If I'm Roman, then I can speak Latin" is true, then it logically follows that the statement "If I can't speak Latin, then I'm not Roman" must also be true.
