1, Gauss is a famous German scientist. His most famous story is that when he was 10, the primary school teacher gave an arithmetic problem: calculation 1+2+3+...+ 100 =?

This stumbles the children who have just learned mathematics. They added up the figures one by one according to the requirements of the topic. But at this moment, there came Gauss's voice: "Teacher, I have calculated it!" " "

The teacher was very surprised. Gauss explanation: because1+100 =10, 2+99 =10/kloc-0, 3+98 =10/kloc-.

2. In the summer when Gauss was three years old, when he was about to get paid, Little Gauss stood up and said, "Dad, you are mistaken." Then he said another number. It turned out that three-year-old Gauss was lying on the floor, secretly following his father to calculate who to pay. The results of recalculation proved that little Gauss was right, which made the adults standing there dumbfounded.
