WebPositive Rational Numbers Ordered Fields Theorem. The subset P:= [(n,d)]:n∈N,d ∈N ⊆Q of the rational numbers is called the set of positive rational numbers. It has the following properties. 1. For all x,y∈P, we have x+y∈P and xy∈P, 2. For all x ∈Q, exactly one of the following three properties holds. Either x ∈P or −x ∈P or ... For every a, b, c, d in F: • Either −a ≤ 0 ≤ a or a ≤ 0 ≤ −a. • One can "add inequalities": if a ≤ b and c ≤ d, then a + c ≤ b + d. • One can "multiply inequalities with positive elements": if a ≤ b and 0 ≤ c, then ac ≤ bc.

Product of two positive numbers (elements of an ordered field) is positive. However, it is not true that if the product is positive, then each of the two factors must be positive.
