## English[edit]

### Noun[edit]

**real number system** (*plural* **real number systems**)

- (mathematics) The complete Archimedean ordered field (of real numbers).
**2008**November, Ambar N. Sengupta, “Notes in Introductory Real Analysis”, in www.math.lsu.edu^{[1]}, retrieved 2012-07-13:- As we have mentioned before, the structure of Euclidean geometry, as formalized through the axioms of Hilbert, produces an archimedean ordered field. To com- plete the story, one can add to these axioms the further requirement that this field is maximal in the sense that it cannot be embedded inside any larger archimedean ordered field. It turns out then that any such ordered field is isomorphic to any other, and thus there is essentially one such ordered field. This ordered field is the real number system
