An integral domain is defined as a commutative ring with 1 that it's elements comply
$x*y=0 Rightarrow x=0 $ or $y=0$
Is this element $0$ the one of $Bbb Z$ or is the neutral element of the set we are working in such ring.

The latter: unless the ring is itself the integers, 0 will mean that ring's additive identity rather than the natural number 0.
And anyways, multiplication is a binary operation $R times R to R$, so unless 0 is an element of the ring, it won't be the product of two elements.
