  1. Algebra of sets - Wikipedia

    • In mathematics, the algebra of sets, not to be confused with the mathematical structure of an algebra of sets, defines the properties and laws of sets, the set-theoretic operations of union, intersection, and complementation and the relations of set equality and set inclusion. It also provides systematic procedures for evaluating expressions, and performing calcul… See more

    Fundamentals

    The algebra of sets is the set-theoretic analogue of the algebra of numbers. Just as arithmetic addition and multiplication are

    Fundamental properties of set algebra

    The binary operations of set union (⁠⁠) and intersection (⁠⁠) satisfy many identities. Several of these identities or "laws" have well established names.
    Commutative property: ⁠⁠ ⁠ ⁠ Associative property: ⁠… See more

    Principle of duality

    Each of the identities stated above is one of a pair of identities such that each can be transformed into the other by interchanging ⁠⁠ and ⁠⁠, while also interchanging ⁠⁠ and ⁠⁠.
    These are examples of an extremely important a… See more

    Algebra of inclusion

    The following proposition says that inclusion, that is the binary relation of one set being a subset of another, is a partial order.
    PROPOSITION 6: If ⁠⁠, ⁠⁠ and ⁠ ⁠ are sets then the following hold:
    reflexivity: ⁠ ⁠ … See more
