Second graders ask for stories of celebrities 30 50 Hurry

The story of the math genius Gauss as a child.

When Gauss was in the second grade of elementary school, once the teacher wanted to take a break after teaching addition, so he came up with a problem and asked the students to do the math, the topic was: 1+2+3+4.........96+97+98+99+100=?I thought that the students would be quiet for a while, but when I was about to find an excuse to go out, I was stopped by Gauss!

It turns out that Gauss has already calculated it, do you know how he calculated, children? Gauss tells everyone how he calculated: adding 1 to 100 and 100 to 1; Arrange in two rows and want to add, that is:

1+2+3+4+……96+97+98+99+100+ 100+99+98+97+96+……4+3+2+1 =101+101+101+……101+101+101+101 There are a hundred 101s, but the equation is repeated twice, so dividing 10100 by 2 gives the answer equal to 5050. Since then, Gauss's learning process in primary school has already surpassed that of other students, which has laid the foundation for his future mathematics and made him a mathematical genius.

One day in 796, a young man began to do math problems left by his mentor.

The first two questions were completed smoothly. There is only the third question left: it is required to draw a regular 17-sided shape using only a ruler and a gauge.

The young man racked his brains, but nothing was done.

Difficulties stir up fighting spirit. He finally got the job done.

The tutor was stunned to see the student's assignment. He said excitedly, "You know what? You've solved a math puzzle that's been left over 2,000 years ago! ”

It turned out that the tutor handed the note to the student because of a mistake.

Whenever he recalled, the young man always said, "If someone had told me that this was a mathematical problem that was more than 2,000 years old, I might never have the confidence to solve it." ”

This young man was Gauss, the prince of mathematics.
