Gauss is a sophomore in primary school. One day, because his math teacher had handled more than half of the things, he still wanted to finish them even though he was in class, so he planned to give the students a math problem to practice. His topic is:1+2+3+4+5+6+7+8+9+10 =? Because addition has just been taught for a long time, the teacher thinks it will take a long time for students to work it out, so that they can use this time to deal with unfinished things. But in the blink of an eye, Gauss had stopped writing and sat there doing nothing. The teacher was very angry and scolded Gauss, but Gauss said he had worked out the answer, which was 55. The teacher was shocked and asked how Gauss worked it out. I just found that the sum of 1 and 10 is the sum of1,2 and 9, 1 1, 3 and 8, 1 1, 4 and 7. And11+1+1+1+11= 55, that's how I calculated it. Gauss grew up to be.

When Gauss was young, he could turn difficult problems into simple ones. Of course, qualification is a big factor, but he knows how to observe, seek the law, simplify the complex and is worth learning and imitating.
