  • artoparts Q.E.D. is an abbreviation of the Latin phrase "quod erat demonstrandum" which means literally, "that which was to be demonstrated", written in its abbreviated form at the end of a mathematical proof or philosophical argument. Latin translation of the original Greek ὅπε�? ἔδει δειξαι (hoper edei deixai) which was used by many early mathematicians including Euclid and Archimedes. Oct 10, 2008
