Less than nothing is really something

the long version

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."
