WebSo you have an integer over in an integer. You have the ratio of two integers. So the sum of two rational numbers is going to give you another. So this one right over here was rational, and this one is right over here is rational. So you take the product of two rational numbers, you get a rational number. WebFeb 14, 2024 · Mathematical induction is hard to wrap your head around because it feels like cheating. It seems like you never actually prove anything: you defer all the work to someone else, and then declare victory. But the chain of reasoning, though delicate, is strong as iron. Casting the problem in the right form Let’s examine that chain.
