Is Zero an Even Number? Investigating the Properties of Zero in Mathematics

[Harmony]

I was wondering if zero is an even number, or it depends on situation?

Even numbers(n) are often defined by the equation n=2k\;\;\;\; n\in\mathbb{Z}. So, yes, zero is an even number.

Conversely, an even number is one that is evenly divisible by 2: there is no remainder. Since 0/2= 0, yes, 0 is an even number.

Shouldn't it be k \in \mathbb{Z} ?

 

[HallsofIvy]

Yes. Probably a typo.

Indeed, well spotted cepheid.
