Why Do Some Numbers Go On Forever?

Imagine you're counting jellybeans in a jar, they come to an end. But some numbers, like π (pi), never stop! They keep going forever with no pattern, just like a never-ending story. These are called infinite numbers. If you write out π, it goes on and on: 3.141592653... and so on, there's no end in sight.
