Gauss was only eight years old when, one morning, like many others, his teacher gave the class a task to add the numbers from 1 to 100. The teacher hoped to keep the class busy for a while ', but the little Carl, evidently led to mathematics, and immediately gave the answer without doing any calculations ... how? Instead of making 1 +2 +3 +4, etc. ... Gauss noticed that 1 +100 = 101, 2 +99 = 101, etc. ... was thus faced with 50 sets of 101, which add up to 5050.
Initiative of the day: try to find alternative solutions to problems we face. We find that there are much simpler and cheaper ways to solve them ... try it!
