## Why do numbers never end?

The sequence of natural numbers never ends, and is infinite. There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.

## Is zillion a number?

## Is the largest number infinity?

A googol is a 1 with a hundred zeroes behind it. We can write a googol using exponents by saying a googol is 10^100. The biggest named number that we know is googolplex, ten to the googol power, or (10)^(10^100). That’s written as a one followed by googol zeroes.
