The first two questions were successfully completed. There is only the third problem left: draw a positive 17 polygon with a ruler.
The young man racked his brains, but made no progress.
Difficulties inspired fighting spirit. He finally solved the problem.
The tutor was shocked to see the students' homework. He said excitedly, "Do you know? You have solved the math problems left over from more than two thousand years! "
It turned out that the tutor handed the notes on this topic to the students because of mistakes.
Whenever I recall, the young man always said, "If someone told me that this is a math problem with a history of more than 2,000 years, I might never have the confidence to solve it."
This young man is Gauss, the prince of mathematics.
