Why Does Infinity Make Math Crazy?

Infinity is like a never-ending candy bar, you can always take one more bite. In math, infinity doesn’t act like regular numbers, so sometimes it feels strange or even crazy.

Imagine you have a bag of marbles that goes on forever. That’s an infinite set. Now imagine you give someone half the marbles, but both the bag and the person still have an infinite number, how is that possible? It's like magic, but it’s actually infinity doing its thing.
