A quick google returns the answer on the parity of zero: Zero is an even number. In other words, its parity—the quality of an integer being even or odd—is even. The simplest way to prove that zero...
Some books say that even numbers start from $2$ but if you consider the number line concept, I think zero($0$) should be even because it is in between $-1$ and $+1$ (i.e in between two odd numbers)...
1 I read on Wikipedia about that zero is an even number. Oke, that it is through. But now the explanation they have given: Why zero is even The standard definition of "even number" can be used to directly prove that zero is even. A number is called "even" if it is an integer multiple of $2$.
2 I have checked the question upon this topic, but everytime the answer is the parity of zero is even because $0\times2=0$, and it is between two odd numbers, $-1,1$. My question is, $0\times\text { (any odd number)}$ is also equal to zero, making the odd number a factor of zero, and thus $0$ could also be said to be odd.
Is zero a number? I've heard that every number is either odd or even, but if $0$ is neither odd nor even, does that mean it isn't even a number?
Common names for the number 0 in English include zero, nought, naught (/ nɔːt /), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (/ oʊ /). Informal or slang terms for 0 include zilch and zip.
