Certainly an abbreviation of quod erat demonstrandum but after watching, suffering through, proving thousands of proofs, a math major might just say Quite Easily Done.

A term mathematicians like to use which literally translates as Qualified Ejaculate Dispenser, where those who have come up with an equal or better theory or postulate can join you in the lab for a celebratory circle jerk. In the film "A Beautiful Mind" this event was replaced with the scene where the other faculty members giving John Nash their pen, some after having the pen in their mouths.

Abbreviation of Latin 'Quod Erat Demonstrandum' meaning 'Which was to be demonstrated'. When doing your geometry exam at St Custard's, you might be required to prove that the square on the hypotenuse is equal to the square on the other two sides. When you think you have given the required proof, you put at the end Q.E.D. In other words. 'That's what you asked me to prove, and I've proved it.'
You asked me to prove the existence of God. God is defined as self-existing, that is, not caused. Everything that exists must be the effect of a cause but the first cause of all other effects cannot by definition be the result of a previous cause. That first cause is therefore God. Q.E.D.
