Q.E.D. or QED is an initialism of the Latin phrase quod erat demonstrandum, meaning "thus it has been demonstrated". Literally it states "what was to be shown". Traditionally, the abbreviation is placed at the end of mathematical proofs and philosophical arguments in print publications, in order to indicate that the proof or the argument is complete.
