When a mathematician writes "QED" at the end of a proof, it stands for the Latin phrase "quod erat demonstrandum," which translates to "which was to be demonstrated." This notation signifies that the proof is complete and that the statement has been successfully established. Traditionally, it serves as a formal conclusion, indicating that the arguments presented have logically led to the desired result.
64 = 8*8 = 8^2 QED. 81 = 9*9 = 9^2 QED. 100 = 10*10 = 10^2 QED. NOTE: 7^2 = 49 < 60 so that fails and 11^2 = 121 > 115 so does this.
Generally: RATE = DISTANCE / TIME -or- DISTANCE = RATE * TIME -or- TIME = DISTANCE / RATE qed
The precursor to a worm cut in half. The two 1's would have originally been just a single 1. QED.
Gather like terms: 3t - t = 13 - 4 ie 2t = 9 so t =4½ Check: 3t = 13½ + 4 = 17½, 4½ +13 = 17½ QED
q = d + 8. 10d + 25q = 515 so 10d + 25d + 200 = 515 ie 35 d = 315 so d = 9 and q = 17 Check 9 x 10 + 17 x 25 = 90 + 425 = 515 QED
QED? it follows a proof...
The mathematical symbol "QED square" is used at the end of a proof to indicate that the theorem has been successfully proven. It signifies the completion of the logical argument and serves as a conclusion to the proof.
QED from the Latin "quod erat demonstrandum", meaning "that which was to be demonstrated", normally put at the end of a mathematical proof
In mathematical proofs, "QED" stands for the Latin phrase "quod erat demonstrandum," which translates to "that which was to be demonstrated." It is typically placed at the end of a proof to indicate that the statement has been proven or demonstrated.
The QED symbol, which stands for "quod erat demonstrandum" in Latin, is used at the end of mathematical proofs to signify that the statement or theorem has been successfully proven. It serves as a conclusion marker, indicating that the argument presented is complete and the proof is finished.
This requires no skill in PROOF, go to a different category man! What's the ratio of 20 to 120? 1/6 QED :P
QED means quod erat demonstrandum- which was to be demonstrated

Yes, "QED" is a commonly used abbreviation for quantum electrodynamics.
It is actually not qed but qid. It's Latin "quater in die" which means four times a day.
