Using them, two pairs of inequalities, well known in the degree induced covering rough set theory, can now be modified to become equalities, respectively. \itemrv{~} \itemcc{} \itemut{degree induced covering rough set; degree covering lower decrement operator; degree covering upper decrement operator; degree covering lower increment operator; degree covering upper increment operator} \itemli{doi:10.1007/978-3-642-23226-8\_63} \end
