The autumn rain that has lasted for several days is finally over. God, it's sunny today.

The yard is full of colorful clothes hanging in the sun, and the bell rubs it every time it passes by.

"Bell, don't bite your clothes!"

Xiaobai sees that lingdang is eager to bite the quilt to dry, so she hurried to drive it over.

Ling Dang bared his teeth and ran to Fang Xing's side. He put his head on his vamp.

"Lazy dog!"

Fang Xing weighed the bell with his feet and watched it close his eyes comfortably. He couldn't help laughing and scolding.

"Young master, someone posted a post."

A servant girl came in with a post in her hand.

Fang woke up, took a look, nodded and said, "tell the visitor that I will go tomorrow."

After the servant girl went, Fang woke up and leaned back on the back of the chair, closed his eyes and meditated.

Zhang Shuhui asked cautiously, "husband, but that?"

Fang woke up, opened his eyes and said with a smile, "yes, that's the guy. The decisive moment has finally come. I'm very excited."

Abacus was already used in Daming at this time, but it was not popularized.

In the field of mathematics, the Ming Dynasty has cancelled the Ming arithmetic in the imperial examination.

At present, some works, such as Tongyuan algorithm, are far behind the level of the song and Yuan Dynasties.

Fang Xing leaned over and touched Ling Dang's head, turned and went to the study.

Ma Su whispered in Fang Xing's ear, "that's called Chen Mao. He studies hard. He's a guest of the Imperial College. He has a great momentum."

Fang woke up and nodded, then occupied a stone table with Ma Su and Liu PU. Xin Laoqi and his servant are behind him.

Chen Mao coughed and walked between the two sides. He glanced at the hundreds of teachers and students who were watching and said, "arithmetic is just a path. We should take knowledge as the foundation, report to the king and the country, and comfort all the people, so as to live up to the learning of saints."

The opening remarks emphasize the importance of Confucianism, which everyone expected.

"Today, Hong Bingzheng raised an objection, saying that Fang Xingxing, a member of the Peking government, stole his arithmetic secrets. Let's bear witness today."

Seeing that both sides were silent, Chen Mao continued: "at present, I have prepared two methods. The first is that both sides argue; the second is that both sides set their own questions to determine the outcome with the number of right and wrong. How about?"

Fang woke up and said faintly, "why don't you argue!"

Argumentation is that in front of everyone, two people argue about arithmetic until one party concedes defeat.

Chen Mao's cheek trembled and turned to Hong Bingzheng.

"And you?"

Those who dare to choose to argue are by no means fake! Otherwise, the saliva could drown him in front of hundreds of students in the Imperial College.

Hong Bingzheng said faintly, "the battle of words is not my strength. I'd better make a question!"

It is reasonable that Fang Xing had the upper hand in this round of selection, but someone immediately continued to praise Hong Bingzheng's virtue.

"Being quick in action and slow in speech, Mr. Hong really has the style of an ancient gentleman!"

Chen Mao asked Fang Xing, "what do you think?"

Fang woke up and spread his hands, "I don't care. Just make a question, just..."

Chen Mao's response was so fast that Fang couldn't react when he woke up.

"In that case, you two will give each other questions. The final outcome will be judged by several professors in front of everyone."

what the fuck!

Fang Xingzhen was a little angry. He thought it was a professor from the National Academy of Sciences who worked out the problem, and then he and Hong Bingzheng answered it. But now it has become that two people have questions for each other. This is not biased towards Hong Bing. What is it?

"Great Confucian? I bah!"

Chen Mao didn't even ask for advice, so he decided on the way to write the question, which made Fang Xing despise the so-called great Confucianism.
