Question

Is $0$ an even number?

Answer 1

Even Number:

An even number is an integer that is evenly divisible by an integer $2$, such that the remainder will always come out to be zero. If on division by $2$, the number leaves a remainder, then the number is an odd number.

Yes, zero is an even number. An even number is formally defined as an integer of the form $n=2x$, where $x$ is an integer.

For example,

$$\begin{gathered} n=2\left(0\right)=0 \\ n=2\left(1\right)=2 \\ n=2\left(2\right)=4 \\ n=2\left(3\right)=6 \end{gathered}$$

Therefore, zero is an even number.
