Exponential growth

Exponential growth is when something increases at a faster and faster rate over time. It's like a snowball rolling down a hill: it starts out small and then gets bigger and bigger as it rolls down. Let's say you start with one cookie. If the cookie grows exponentially, it will double every day. So, the next day you would have two cookies, the day after that four cookies, and so on. Eventually you would have a huge amount of cookies! It works the same way with other things too, like money in the bank or bacteria in a dish.
