Examples

“The unique maximal ideal of a (commutative) local ring⟳ contains all of the zero divisors of such ring⟳, and all elements of the ring⟳ outside of it are units. Then in a local ring⟳, the sum of any two zero divisors is also a zero divisor. Contrapositively, if two ring⟳ elements add⟳ up to a unit then one of them must be a unit as well. A simple example of a local ring⟳ is #92;mathbb#123;Z#125;#95;8.”
