Less than nothing is really something

From the jacket flap: "This is a book about negative numbers. It does away forever with the myth that numbers begin with 1, go on to 2, then to 3, and continue from there. Those are just positive numbers. By means of the number line and a new and interesting game, Robert Froman shows that although positive numbers are the ones we usually think about, negative numbers abound in our everyday lives. We often use negative numbers, although we may not be aware of it."
