Article description: (description)
This attribute controls the content of the description and og:description elements. | In axiomatic set theory and the branches of logic, mathematics, and computer science that use it, the axiom of extensionality, or axiom of extension, is one of the axioms of Zermelo–Fraenkel set theory. Informally, it says that two sets A and B are equal if and only if A and B have the same members. |
