Confusion around definition of greatest common divisor. Webof all zero-divisors of a ring R; denoted Z(R); is not always closed under addition. In Z 6, we see that 2 and 3 are zero-divisors, but 2+3 is not. Hence, Z(R) is typically not a subring and thus also not an ideal. Recently, a new approach to studying the set of zero-divisors has emerged from an unlikely direction: graph theory. the underground railroad was
