The LaTeX part of this answer is excellent. The mathematical comments in the first paragraph seem erroneous and distracting: at least in my experience from academic maths and computer science, the OP's terminology ("integers" including negative numbers, and "natural numbers" for positive-only) is completely standard; the alternative terminology this answer suggests is simply wrong.By assuming that √2 is rational, we were led, by ever so correct logic, to this contradiction. So, it was the assumption that √2 was a rational number that got us into trouble, so that assumption must be incorrect, which means that √2 must be irrational. Here is a link to some other proofs by contradiction:The Symbol Denoting Irrational Numbers. In mathematics, irrational numbers are commonly denoted by символът "π" (pi).
