Usage notes
* 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.
