Boolean algebra   (inglés)

Definición Nivel 3

Algebra in which we consider a set S and two commutative
operations + and ×, with the rules that:
  1. each of the operations has an identity element in S, and these
    elements are not the same;
  2. each operation is distributive over the other;
  3. each element has an inverse in S under each of the operations.

Note that the operations + and × are not quite the same as for the ordinary numbers.
This kind of algebra is widely used in logic and set theory.
