Hundred Factorial !


That ! button on the calculator doesn’t get much attention pre-A level, and here’s one more reason why not – it’s not even useful for questions like this that are all about ! !


The Problem :

10!  means 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 and has 2 zeros on the end.

Check this.

With how many zeros does the number 100! end ?
