Question 1004586: You need to arrange 7 of your favorite books along a small shelf. How many different ways can you arrange the books, assuming that the order of the books makes a difference to you? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! The answer for arranging n items is in n! ways...in this case, you can have any of seven books first, then any of six second, and so on...
The answer is 7! = 7*6*5*4*3*2*1 = 5040 ways.
