There was a little boy who had just learned to count on his fingers. One day his uncle came to visit and the boy was anxious to show off his newly acquired skill. He told the uncle to ask him and addition question.

So the uncle asked, "What is three plus four?" The little boy counts it out on his fingers and said, "Seven."

The uncle said, "Listen kid, you can’t count it out on your hands because someday when you are in school, a teacher will get mad at you for it. Now put your hands in your pockets."

So the little boy put his hands in his pockets and his uncle asked, "What is five plus five?"

The uncle saw movement in the boy’s pockets, then the boy said, "Eleven."
