    One afternoon some boys made a lot of noise in class. The teacher got angry. He kept them in the

classroom after school. He told them to add all the numbers from 1 to 100 together.

    The boys took out their exercise-books. All of them began to write the numbers down except one

boy. He was new in the school. He looked out of the window for a few minutes. Then he wrote a

number in his exercise-book and put up his hand.

    "May I go home, sir?" he asked. "I know the answer now."

    The teacher and the other boys were very surprised.

    "Bring it here." said the teacher.

    The next morning, the teacher asked the boy. "How did you find the answer so quickly?"

    "Well,sir." He said, "I did not want to stay here so long. So I did my best to find the answer quickly.

Soon I found it. You see, if you add 100 to 1, you get 101, and 99 and 2 is 101, 98 and 3 is 101 too,

and when you reach 51 and 50, you have 101 fifty times, that is 5050".

    After this, when the teacher gave the class exercises to do, he gave this boy different exercise. The

boy's name was Karl F.Gauss. When he grew up, he became a great scientist.
