WebConsider a set S ( nite or in nite), and let R be the set of all subsets of S. We can make R into a ring by de ning the addition and multiplication as follows. For two subsets A,B, de ne A + B = A [B nA \B (sometimes people call this the symmetric di erence, or \exclusive or"). De ne subtraction by A = S nA (the set-theoretic complement). Web25 Mar 2024 · A set A is called a subset of a set B (symbolized by A ⊆ B) if all the members of A are also members of B. For example, any set is a subset of itself, and Ø is a subset of any set. If both A ⊆ B and B ⊆ A, then A and B have exactly the same members. Part of the set concept is that in this case A = B; that is, A and B are the same set.
