Q.E.D. (also written QED and in italics: QED) is an initialism of the Latin phrase "quod erat demonstrandum" meaning "what was to be demonstrated" or "what was to be shown."[1] Some may also use a less direct translation instead: "thus it has been demonstrated." Traditionally, the phrase is placed in its abbreviated form at the end of a mathematical proof or philosophical argument when the original proposition has been restated exactly, as the conclusion of the demonstration or completion of the proof.
