Airi: Alright, limits are when we approach a certain number or value. It's like although we never quite reach it, we come really close. Here's an example: if you keep adding more and more seconds to your age, you'll eventually be 50 years old. But before then, there will be moments where you are getting extremely close to being 50 but haven’t yet reached it... This is what limits help us understand!
