Possible Proof by Induction/Very Basic While Loop

WebProof. The assumption a < b is equivalent to the inequality 0 < b − a. By the Archimedian property of the real number field, R, there exists a positive integer n such that n(b− a) > 1. Of course, n 6= 0. Observe that this n can be 1 if b − a happen to be large enough, i.e., if b−a > 1. The inequality n(b−a) > 1 means that nb−na > 1, Web1. Motivations. There have been many attempts to define truth in terms of correspondence, coherence or other notions. However, it is far from clear that truth is a definable notion. In formal settings satisfying certain natural conditions, Tarski’s theorem on the undefinability of the truth predicate shows that a definition of a truth predicate requires resources that go …
