What is the only number that is both even and odd?

.

Similarly one may ask, is 0 an odd number or even?

Zero is an even number. In other words, itsparity—the quality of an integer being even orodd—is even. This can be easily verified basedon the definition of "even": it is an integermultiple of 2, specifically 0 × 2. In this sense,0 is the "most even" number ofall.

Also, can an odd product have an even factor? So, odd times even is alwayseven.” Here is the logic behind the multiplicationrules: an even number is divisible by 2, so that means ithas 2 as a factor. And when two integers aremultiplied, their product has all of the factors ofboth numbers: the factors accumulate.

In this regard, what is the only even prime number?

What is so odd about odd numbers?
