## Compare Them

When comparing real numbers, it can help to think of the number line. Ah, how fondly we remember it. Our favorite line of all the lines.

The numbers on a number line get bigger as we go further right on the number line, and smaller as we go further left on the number line.

So then why doesn't a number line look like this?

Good question. Write your congressman.

All positive numbers are bigger than zero, and all negative numbers are less than zero. Doesn't mean they can't be friends.
