WebJul 11, 2024 · Since the way an element of $\mathbb Z^3$ is a zero divisor is if one of its coordinates is zero, what matters in an example is which coordinates are zero. One might ask "are there any examples that are not of the form "$(x,y,0),(z,0,w),(0,s,t)$" (as such examples are fundamentally relying off of the same key idea as the given example). WebAug 21, 2016 · 1 Answer. A zero divisor in R is a nonzero element a ∈ R such that there exists b ≠ 0 so that a b = 0. If R = R 1 × R 2 is a product of rings, then it's easy to show that ( a 1, a 2) ∈ R is a zero divisor iff one of these two conditions holds: Therefore, as Z 3 has no zero divisors (it's a field) and Z 6 has 2, 3, and 4 as zero divisors ... login to physics walla
