Robert dreamed only nightmares. Sliding down an infinite slide
or being eaten by a stinky fish were two of the most common.
So, you can imagine the relief when he dreamed that he was in
a meadow, with grass that reached the sky and an odd, tiny, red
man with horns and a goatee. He says he is "the number devil".
As the nights he dreams of him increase he begins to make friends
with the little devil. Although easy to anger the devil produces
magical wonders, such as a walking stick that will write on anything,
or a calculator as big and fuzzy as a couch (or green and slimy).
But in the end Robert learns to love mathematics and the number
devil gives him the best gift possible.
