 Spanish term or phrase: principio del buen orden Hello, I am translating someone's transcripts from Mexico (ITAM - Instituto Tecnológico Autónomo de México), and there is one particular part of a course where I can't find an appropriate English equivalent. Here is the entire paragraph: "El principio de inducción matemática. Demostraciones mediante inducción matemática. El principio de inducción matemática modificado. ***El principio del buen orden.*** Relación entre ***el principio del buen orden*** y el principio de inducción matemática." I have done a lot of searching already, so please don't answer unless you have a plausible answer (i.e. "principle of good order" or "good order principle" will not work). Thanks!

 Thank you very much to both answerers. I researched both terms, and found this article: "An important and fundamental axiom in set theory sometimes called Zermelo's axiom of choice. It was formulated by Zermelo in 1904 and states that, given any set of mutually exclusive nonempty sets, there exists at least one set that contains exactly one element in common with each of the nonempty sets. The axiom of choice is related to the first of Hilbert's problems. In Zermelo-Fraenkel set theory (in the form omitting the axiom of choice), the Zorn's lemma, trichotomy law, and the well ordering principle are equivalent to the axiom of choice (Mendelson 1997, p. 275). In contexts sensitive to the axiom of choice, the notation "ZF" is often used to denote Zermelo-Fraenkel without the axiom of choice, while "ZFC" is used if the axiom of choice is included." So apparently these are two different concepts (although it says they are equivalent).4 KudoZ points were awarded for this answer

-> Gracias Urico! =:)

neutral  neilmac: Could be, but sounds a bit odd, like "goodness of fit"

-> It does sound odd. The references are quite sound though. It would be nice to hear from a mathematician. Thanks for your comment neilmac =:)

Axiom of choice

Explanation:
In mathematics, the axiom of choice is an axiom of set theory. It was formulated in 1904 by Ernst Zermelo and has remained controversial to this day. It states the following:

Let X be a collection of non-empty sets. Then we can choose a member from each set in that collection.

Stated more formally:

There exists a function f defined on X such that for each set S in X, f(S) is an element of S.

Another formulation of the axiom of choice (AC) states:

Given any set of mutually exclusive non-empty sets, there exists at least one set that contains exactly one element in common with each of the non-empty sets
