You'll need to be more specific. What parts do you understand? What parts don't you understand? I mean, do we need to explain the word "integer", or can we start somewhere in the middle?

And since that text is obviously from my Learning Perl book, I need to ask if you meet the prerequisites of the book. What other languages have you already programmed in?
