The approximation of difference of two linear positive operators having different basis functions is discussed in the present article. The quantitative estimates in terms of weighted modulus of continuity for the difference of Lupaş operators and the classical ones are obtained, viz. Lupaş and Baskakov operators, Lupaş and Szász operators, Lupaş and Baskakov-Kantorovich operators, Lupaş and Szász-Kantorovich operators.
