Clear elements and clear rings

open access: yes, 2020
An element in a ring $R$ is called clear if it is the sum of unit-regular element and unit. An associative ring is clear if every its element is clear. In this paper we defined clear rings and extended many results to wider class. Finally, we proved that a commutative B zout domain is an elementary divisor ring if and only if every full matrix order 2
