ROUGH RINGS, ROUGH SUBRINGS, AND ROUGH IDEALS

open access: yesJournal of Fundamental Mathematics and Applications (JFMA), 2022
The basic concept in algebra that is set theory can be expanded into rough sets. Basic operations on the set such as intersections, unions, differences, and complements can still apply to rough sets. In addition, one of the applications of rough sets is the use of rough matrices in decision making.
