Abstract
Let U be a non-empty set and R an equivalence relation on U. Then, (U,R) is an approximation space. The equivalence relation on U forms disjoint equivalence classes. If X⊆U, we can form a lower approximation and an upper approximation of X. If X⊆U, then we can form a lower approximation and an upper approximation of X. In this research, rough group and rough subgroups are constructed in the approximation space (U,R) for commutative and non-commutative binary operations.
