The aim of this paper is to point out and correct some errors of two theorems for IFSs in Atanassov ([[Issue:Two theorems for intuitionistic fuzzy sets|Two theorems for intuitionistic fuzzy sets]], [[Fuzzy Sets and Systems]], 2000) and bring forward a new theorem for IFSs. In the end, some elementary, but non-standard equalities between IFSs were formulated.&lt;br /&gt;
