What is the purpose of QD requirements
QED, Fermat's Last Theorem.
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.
QED? it follows a proof...
A key part of Quantum Electrodynamics (QED) is the concept of virtual particles, which are constantly being created and annihilated in the vacuum. These virtual particles mediate interactions between charged particles, leading to phenomena such as the electromagnetic force.
Q.E.D is Latin for "quod erat demonstrandum" which translates into either "which was to be demonstrated" or "thus it is demonstrated.
Quoted from the related link,"The Quantum Entanglement Device (QED, and called the Richtofen Device by Richtofen) is a secondary tactical grenade appearing on the zombie map level Moon. The QED's effect is random. The QED is capable of creating many different outcomes. Upon toss, the player will spin the handle on the bottom once, and push it in. It can either "Curse" or "Bless" the player, with outcomes such as extra weapons, extra perks, more enemies, or a reset of points."More detail are available at the related link and also for the Moon related link
One is in Japan and the other is in China, QED.
