Yesterday we talked about the chicken and rabbit cage problem.
Today, let’s talk about another famous issue in Chinese history.
Han Xin’s problem
Han Xin’s soldiers are now often seen in various exams.
I said that Han Xin once wanted to know how many soldiers he had.
He will let his own soldiers
Every 3 people line up in a row
Let these soldiers have a list of 5 people and find that there are still 3 people left.
Let these soldiers have 7 people, and there are two people left.
Then ask you how many people are there?
This problem was first thought of in our case.
Classical mathematical masterpiece "The Son of the Sun"
The solution to the problem given by Sun Zi’s calculations is:
Three people walking seventy
Five Tree Plum Blossoms 21
Seven sub-groups are half a month
Learn 100 minus five
What is this theorem called us?
We are called the grandson theorem or the Chinese remainder theorem
So in our ancient times, there were still many mathematical achievements.
