# 16+ Entrance Examinations!! HELP watch

1. Hey guys! Thanks for stopping by to help me out!!,

I am having a bit of an issue understanding these questions

The factorial operator "!" is defined such that:

n! = n x (n - 1) x (n - 2) x ... x 3 x 2 x 1
ie. 4! = 4 x 3 x 2 x 1
= 24

Simplify the following, giving your answer in the form a/b (a over b) where a and b are integers

24! + 4! x 13!
5! x 23! 15!

im completely stumped
6. Could you clarify the question please? I see you have underlined some things... Is that to represent division?

So the question is [24! +4! x 13!] all divided by [5! x 23! x 15!] ?
