I’m guessing you mean the different order in which you can arrange the books. If this is the case think about what you do. You place one of the seven books on the shelf first, then you’ll have six left. Place another on the shelf and you’ll have five left. so for the first book you have seven different options to choose from, then six, then five and so on. All you do is 7! Which means 7•6•5•4•3•2•1. This means there are 5040 different ways to arrange the books. Hope this helps!
