The aim of this study is to obtain several inequalities involving the Berezin number and the Berezin norm for various combinations of operators acting on a reproducing kernel Hilbert space. First, we present some bounds regarding the Berezin number associated with W*Q+W*Q′{W}^{* }Q+{W}^{* }Q^{\prime} , where WW, QQ, and Q′Q^{\prime} are three bounded linear operators. Next, several Berezin norm and Berezin number inequalities for the sum of nn operators are established.
