From Latin quod erat faciendum (what was to have been done), from Ancient Greek ὅπερ ἔδει ποιῆσαι (hóper édei poiêsai).

Phrase

QEF

  1. “quod erat faciendum”, “what was to have been done” – used to end a mathematical passage other than a proof.
Usage notes
[edit]

Much less used than QED. Traditionally used to end passages other than proofs, such as geometric constructions – a “how-to”, not a persuasive argument.
