Well, a factorial (n!) is a type of equation in which you multiply a number by itself, the number below it, and so on until you reach one. (Ex: 2! = 2 * 1, and 9! = 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) For n! = 110, there is no number n, for the closest n is 5, and 5! = 120. Are you sure it's 110 and not 120?

exactly. I'm pretty sure you cant do decimals, so essentially...

 

     n! = 110
