What?! What?!?!?!?!

Exclamation marks. It’s not that. It’s called FACTORIAL.

A factorial of a number is basically “multiply all the numbers from one to the number” sort of thing. So 4! would be 24, 5! is 120, and 10! = 3628800.

Factorials are like, everywhere. e equals the infinite sum of n equal to 0 towards infinity, 1/n!. Whew! And boringly, n! = n(n-1)!. I guess you figured that out already. BORING!!!!!

Anyway, what is g? I want to know what number yer talkin’ about.

The author, who is now lazy

By the way, 0! = 1. It might be tempting to say it’s 0, but 1! = 1 and 1=1*0! so 0! is 1. 2! is the number 2!!!!!!!!!! And no matter how many times you factorial it, it will always be 2.

I’m lazy, so I’m going to finish it there. I will talk about transcendental numbers in a few years (wink wink nudge nudge).๐๐๐๐๐โบ๐๐๐๐๐
