## Keep track of these numbers as they get bigger!!

Check out these numbers! Learn the names of some very large numbers that you don’t often hear used in everyday life and find out just how big a septillion, octillion and nonillion are. Do you know what a googol is? What about a centillion? Well read on and find out! These numbers are sure to boggle your minds, but better yet- you can use these numbers to surprise others who haven’t heard of them. Let’s find out how long these numbers are and how you can write them in words.

One googolplex = The number 1 followed by a googol zeros (there really isn't enough space in the universe to write this number down! Seriously!!)

You must be familiar with the term infinity. Well, while we do not consider it as a number, the term ‘infinity’ refers to a limitless quantity. Infinity is represented by a symbol that looks like the number 8 placed on its side.
