The 47 pages that link to Natural number, each with the reason it gives.

• Set theoryBroader topic: In set-theoretic foundations, natural numbers can be constructed from sets.

• Zermelo–Fraenkel set theoryBroader topic: The Infinity axiom supports constructing the natural numbers within the theory.

• ElementBroader topic: Natural numbers can be treated as elements of sets such as the integers.

• Infinite setBroader topic: They form the standard example of a countably infinite set.

• Uncountable setBroader topic: Uncountability is defined by failure to match this set in a bijection.

• Axiom of infinityBroader topic: The axiom ensures a set large enough to contain every finite successor stage.

• Even numberBroader topic: Even natural numbers are one restricted part of the even integers.

• Number (mathematics)Broader topic: Natural numbers provide the basic counting numbers from which broader systems are developed.

• Axiom of Empty SetBroader topic: In the von Neumann construction, zero is identified with the empty set.

• Element of a setBroader topic: Natural numbers provide familiar objects whose membership in number sets can be tested.
