PI is the representative of the highest achievement in ancient mathematics, which not only achieved the Taishan status of Zu Chongzhi\'s mathematics, but also won the glory of the Zu family for hundreds of years.

"After reading it, return it immediately! It can\'t be damaged!"

Zu Mingjun handed Merton a yellow ancient book.

Merton took it in surprise, turned over the title page, closed it quickly, and looked at Zu Mingjun in surprise. It turned out to be Zu Chongzhi\'s computational legacy.

"It\'s not appropriate!" Merton shook his head, which was the most precious treasure of the ancestral family.

"You deserve it!"

Zu Mingjun said that this is the return of the Zu family for teaching Merton Arabic numerals and enlightening Zu Mingjun to discover parabola.

"There are the notes of ancestors on conjugation. I know your level of arithmetic is very high. It is estimated to be helpful to you!" Zu Mingjun said.

"Annotation of conjugation!" Merton looked a little moved. He had heard a lot about conjugation. Later generations recorded that conjugation could not be understood by even academic officials and directly abolished conjugation.

Guozijian also has textbooks on conjugation. Merton has read them and found that the root of conjugation is the limit method of later generations.

With Datang\'s current level of mathematics, it is indeed obscure and difficult to understand, and there is no theoretical formula support. It only relies on a large amount of data accumulation, which is time-consuming and laborious, and the result is not accurate. It is estimated that other people in the Imperial College can only ha ha except Shen Hongcai.

Merton couldn\'t resist his curiosity and couldn\'t help turning it over. He found that the wisdom of the ancients really can\'t be underestimated. In this ancestral work, it was mixed with various extremely complex mathematical problems of later generations, and even mentioned the concept of calculus.

Unfortunately, there are too few people who can accept things that are too advanced. No wonder conjugation has been lost in future generations.

Merton quickly turned it over from beginning to end and quickly returned the secret script to Zu Mingjun.

"The wisdom of our ancestors is amazing, but I advise you to forget the things inside and concentrate on studying parabola. In the future, you should have a chance to study these things when you are 70 and 80 years old, so as to save a lot of good time." Merton said kindly.

Now the basis of Datang\'s mathematics is not up to the level of studying such a profound mathematical problem. If you insist, you can only waste your time.

"This was originally studied by those old guys." Zu Mingjun whispered. However, his eyes were slightly regretful. Obviously, he also wanted to understand the legacy of his ancestors and become famous in one fell swoop, but even Merton, who was much better at mathematics, said so, and he had to give up.

"Can you understand?" Zu Mingjun asked.

Merton smiled and didn\'t answer.

Although he knows the methods, arithmetic is developed step by step. If he encourages it, it will only destroy the foundation of arithmetic. Moreover, these profound problems are of no use in Datang and are not as practical as the parabola in front of him.

Qin Huaiyu and his classmates showed great enthusiasm for Mathematics in a short time. For the first time, they joined Zu Mingjun\'s parabola experiment. Of course, it is more likely that they heard that the equipment for today\'s experiment is to let them play Cuju.

"Attention, everyone! Cuju is coming, look at the young master!" Wei Chi Baolin roared and kicked Cuju into the sky with a run-up. This guy is as strong as an ox, just like an animal, tireless and energetic.

Zu Mingjun took the paper and watched Cuju climb in the air. When it reached the highest point, it fell in a parabolic state! It fell to the ground and popped up a long way.

"The height is two feet and three feet."

Merton stood in the middle, watched the Cuju pass through the line between two and three feet high, and reported a relatively close height.

"The landing point is thirty feet and two feet!" Qin Huaiyu shouted at the landing point. His data are much more accurate. Where the landing point is, he will report how far it is.

When Zu Mingjun heard the cry, he quickly recorded the data in the booklet. Looking at the dense booklet, it was obvious that he had recorded it many times.

At the landing point, Chumo picks up the Cuju, kicks it out at the landing point, and the Cuju crosses the air again.

"Eight feet high," Merton shouted again.

"The landing point is twenty feet and one." seeing the distance of the landing point, Zu Mingjun quickly wrote down the data again. Looking at the dense data in his pamphlet, it is obvious that he has recorded a lot.

Through a large number of experiments, it is a real number to approach again and again. This is the conjugation handed down by the ancestors from generation to generation. Of course, there is also its own unique calculation method. Although it is clumsy, as long as it is persevered, it will be able to make achievements.

"Are you ready?" Chumo kicks Cuju away again and yells.

Rao Shihe and Yuchi Baolin are strong, but they can\'t stand playing Cuju hundreds of times in a row. They are tired and panting.

"Well, ten more groups, and I\'ll treat you to fried chicken!" Zu Mingjun shouted.

"You\'re really cunning. You\'re in our shop and invite us to eat!" Wei Chi Baolin looked at Zu Mingjun contemptuously and kicked Cuju away.

"That\'s not to take care of your business!" Zu Mingjun took advantage of it.

"Cut! Use you?" Qin Huaiyu shouted in the distance.

Since the fried chicken chops and fried chicken legs were launched, they have been widely praised, especially the students in the Imperial College and the teenagers in Chang\'an. They line up all the way every day and don\'t worry about business at all.

Cuju came and went in the air, and soon ten groups of data were recorded. Zu Mingjun looked at his pamphlet. With the help of these two animals, today\'s data has been collected, which can support him for a few days.

Merton wiped his sweat and walked to Zu Mingjun. Looking at the dense data in the booklet and Zu Mingjun\'s confident smile, he believed that the parabola was no longer a problem for Zu Mingjun and could be summarized in a certain time.

At this time, an unexpected man appeared in front of Merton.

"Merton, I want to learn new arithmetic from you?" Kong huisuo came to Merton and said with expectation.

In fact, Merton had already seen Kong huisuo hovering around, but he didn\'t expect to find himself.

With the character of Qin Huaiyu Sao Bao, the secret of the rapid improvement of their arithmetic level was soon known to everyone. They boasted in front of Guozi supervisor every day that they could learn arithmetic so simply. In addition to their talent and intelligence, the exotic arithmetic taught by Merton may also play a role.

"Played a role?" the person who heard this looked contemptuously at the flaunting Qin Huaiyu,

They don\'t know what this guy\'s previous level is. I\'m afraid it doesn\'t play a role, but most of the credit is this exotic arithmetic!

It can teach the scum with a very poor level of mathematics into a learning bully in a short time. This foreign mathematics is almost deified in the Imperial College.

It was Merton, the son of the Mohist school, who mastered this kind of foreign arithmetic. Many people couldn\'t open their face to go to Merton. However, Kong huisuo is different. Since Qin Huaiyu\'s arithmetic achievements have improved by leaps and bounds, Kong huisuo has become the lowest among the prison students. He has no way out, and all his hopes are concentrated in Merton\'s foreign arithmetic.

"Of course! This kind of arithmetic is brought back by the ancestors of Mohism from Tianzhu. It is not unique to Mohism. Everyone can learn it," Merton said.

"Everyone can learn?" Kong huisuo was surprised. He didn\'t expect to get this foreign arithmetic easily.

"That\'s true. Brother Mo really teaches us arithmetic knowledge for free. Here are my notes. Take them first. If you don\'t know anything, you can ask me." Zu Mingjun proved Merton\'s words, took out a note of his own memory from his bag and handed it to Kong huisuo.

"Thank you!" Kong huisuo said sincerely with his notes.

Watching Kong huisuo leave with his notes, Merton smiled. Whether it was ordering Zu Mingjun to study parabola or teaching Arabic numerals and multiplication formulas, it was spreading the seeds of arithmetic.

Only when mathematics has been really spread, can Mohism relying on mathematics really flourish.
