Abstract
In this chapter we deal with the basic theory of ordered fields. In particular, we show that every ordered field admits a uniquely determined “real closure.” In the theory of ordered fields, this real closure plays essentially the same role as that played by the algebraic closure in the theory of fields. In the exercises at the end of this chapter we shall give several methods to construct ordered fields.
