ELI5: Explain Like I'm 5

Large numbers

Okay, imagine you have some buttons. Maybe you have a few buttons in your pocket, or maybe you can picture a big jar full of buttons. Whatever works for you.

Now, let's imagine you have a LOT of buttons. I'm talking a really, really big number of buttons. So many buttons, you couldn't count them all by hand.

When we talk about large numbers, we're talking about numbers that are too big to count one-by-one. You might have heard of numbers like a million or a billion-- those are both examples of large numbers.

But what happens when we get even bigger than that? Well, we start using special words to talk about these REALLY large numbers. Words like trillion, quadrillion, quintillion, and so on.

Each of these words represents a much larger number than the one before it. For example, a trillion is a thousand times bigger than a billion. And a quadrillion is a thousand times bigger than a trillion.

So if you had a jar with a quadrillion buttons in it, that would be a whole lot of buttons. And if you wanted to count them all, you'd probably need a computer to help you out!

In summary, large numbers are numbers that are too big to count by hand. We use special words like trillion and quadrillion to talk about these really, really big numbers.
