There is a story told about the famous mathematician, Carl Friedrich
Gauss, when he was ten years old. His school instructor gave his class
the problem of adding up all the numbers from 1 to 100 to keep them busy
for a while. Instead of doing all the hard work of adding these numbers,
little Gauss thought of how he could conceptually reverse the order of the
last 50 and place them under the first 50:
1 + 2 + 3 + ... + 50 +
100 + 99 + 98 + ... + 51
so as to get 50 pairs, each with a sum of 101, so he had only to multiply
50 x 101 to get 5050.
