Oh JB, the level of bureaucracy "down there" at first blush amazes me! But then I realize "we" have many of the same requirements. My latin is severely lacking, so I looked it up. As many of your posts, you made me think then smile so thanks for that.

Q.E.D. is an initialism of the Latin phrase quod erat demonstrandum, meaning "which is what had to be proven". The phrase is traditionally placed in its abbreviated form at the end of a mathematical proof or philosophical argument when what was specified in the enunciation—and in the setting-out—has been exactly restated as the conclusion of the demonstration.
