Abstract
Two new pairs of operators are defined in covering rough set and their properties are discussed . Using them, two inequalities well known in the covering rough set theory can now be modified to become equalities. With the change, no information will be lost in the new expressions. Finally, we prove that the two pairs of operators are equivalent.
