WebProposition: There are rational numbers that behave like zero and one. For any a, b ∈ , with b ≠ 0, we have: a/b + 0/1 = a/b, a/b * 1/1 = a/b, a/b * 0/1 = 0/1. Proof: Proofs incorporate the definitions and properties of natural numbers. • Thus 0/1 behaves like zero in the natural numbers, 1/1 behaves like one, and for any non-zero b, b/b ... http://cgm.cs.mcgill.ca/~godfried/teaching/dm-reading-assignments/Contradiction-Proofs.pdf
