    By factorial method we counts how many ways a thing can happen . When we say a thing can happen only one way we can say either 0!or 1!

    This method which i understood why 0!=1. Now if u want 9! U will do 10!/10,if u want 8! U will do 9!/9 similarly so on still 2!/2=1! then same way for 0!(zero factorial what u need) u will do 1!/1 hence u will get 0!=1! Which is nothing but 1. Hope understood this.there are many other way also but this one gave satisfaction to me.
