WebJan 11, 2014 · The integers are closed under addition. Any finite sum of integers is an integer. The integers are also complete under the usual metric. If an infinite series of integers converges in this metric, it must converge to an integer. The series $1-2+3-4+\cdots$ does not converge; its "sum" does not exist. simple webdav 配置Weba) Addition is well de ned, that is, given any two integers a;b, a+b is a uniquely de ned integer. b) Substitution Law for addition: If a = b and c = d then a+ c = b+ d. c) The set of integers is closed under addition. For any a;b 2Z, a+ b 2Z. d) Addition is commutative.
