Most numbers we deal with are nice fractions or decimals, but sqrt(2) goes on forever without repeating. I've seen the proof by contradiction that assumes it's a fraction and shows it's impossible. But why does such a simple length have such a complicated number?
Beyond basic arithmetic, I'm wondering which mathematical idea gives you the most practical benefit in everyday decision making. Is it probability? Statistics? Understanding exponential growth? I want to know what single concept would help the average person the most.
