After entering primary school, Gauss became more interested in mathematics. However, his math teacher Bert always thinks that rural children are little idiots. Not only do they not prepare lessons carefully, but they often reprimand students for no reason.
One day, Bert was a little unhappy again. As soon as he entered the classroom, he said with a straight face, "Today, you do the math yourself. Whoever eats first will go home for dinner. " After that, I wrote such a topic on the blackboard: 1+2+3+...+ 100 =? The students quickly took out their exercise books and bowed their heads to calculate. Where's Burt? Then I just sat there reading a novel. But as soon as he had read two pages, little Gauss raised his hand and reported, "Teacher, I have finished writing."
"finished?" Bert waved angrily. "You are wrong to calculate so quickly!"
"There is nothing wrong, I have already checked." Gauss said confidently.
Bert went to Gauss's seat and picked up his exercise book. The answer is "5050", exactly.
"How do you calculate?" He asked in surprise.
Gauss replied practically: "I found that the sum of the two numbers in this question is 10 1, and there are 50 10 1, so the number of answers is 50×10/= 5050."
"Great!" Baxter patted the table excitedly and then said to all the students, "I didn't expect that there would be a math prodigy among you!" " "
Since then, Bertrand has changed his view of rural students. He especially likes Gauss and often gives him individual tutoring. Under Bertrand's careful training, Gauss became more and more interested in mathematics and made more and more achievements. At the age of seventeen, he discovered the law of quadratic reciprocal in number theory.
