I've broken it down to a problem like this: Let x=99! Then 100! = 100*99! = 100x. 100x - x=99x = 99*99!.

I can't figure out a way to simplify the problem any more than that.

Thank you in advance for any help.

There is the obvious: 100!- 99!= 99!(100- 1)= 99!(99).

As is seen, "!" does not satisfy the distributive law for operations.
