Paritas zeri
(Redirectum de Paritas cifrae)
Paritas zeri seu paritas cifrae seu paritas nullius rei est notio quae statuit numerum zeri esse parem et non imparem.[1][2] Ad notionem demonstrandam, satis est quaerere num zerus definitioni numeri paris congruat, velut sit numerus integer multiplus duorum: zerus est multiplus duorum, nam 0 = 2 × 0, ergo zerus est par. Quam ob rem, zerus proprietates omnes parium numerorum communicat: in partes duas dividitur, et utrisque lateribus imparibus numeris coniungitur.[3]
