Daming: Wanted to be a small landlord, but was forced to ascend the throne

Chapter 65 Arithmetic subject not abolished?
"The lord is very concerned about the country and the people, worthy of the late emperor's love, but don't worry too much, be careful of your body."

Li Ji regretted bringing this matter up and made his prince worry.

"You tell the direction that you don't need to come here to trouble him. When he has written those things, you can take my seal and stamp it."

"Yes!"

……

After the matter of raising seedlings and planting was over, Qin Shao reduced the number of times he went to the farmland, and let Wang Yin go to watch when he had time.

Wang Yin has almost learned the skills of farming. He is a pretty fair boy, but now he has become a black man of steel.

But he likes this skin color very much, and he is also a lot more cheerful.

Little Sanzi is like a mud monkey all day long, either catching fish or catching shrimps, life at home has improved a lot.

Han Jinrong is good at cooking, and even the old man Zhu got a lot of benefits, and he still eats food from time to time.

But I wish the old man didn't relax in his study, let him recite those four books and five classics every day.

I can recite it upright, and let me recite it backwards. Sometimes I randomly extract a sentence to explain the meaning.

Every day in his dreams, he sometimes babbled about those texts.

He has also improved a lot in calligraphy, but the old man is still very dissatisfied.

He couldn't help but pick and choose calligraphy all day long.

These are almost the same, and start to learn arithmetic again!
Qin Shao was a little surprised. He seemed to remember that the later dynasties of the Ming Dynasty abolished the arithmetic department?

How did you learn it again?

However, the old Zhutou gave up learning, which means that it is an exam. After all, the records of later generations may be wrong.

Da Ming's arithmetic is very simple. What he learned is "Nine Chapters of Arithmetic". The content of the county examination is actually some things like addition, subtraction, multiplication and division. It is very simple, equivalent to the level of the first and second grades of elementary school in the previous life.

However, arithmetic is a skill in Ming Dynasty, and many civil servants in Ming Dynasty are technicians, so they need to master these skills.

And there are not many teachers who can count, and ordinary people don't know the words, and they don't have the opportunity to touch such advanced things.

The old man Zhu wanted to embarrass Qin Shao in arithmetic, but his face was a little green when he saw that he solved those arithmetic problems with three times, five and two divisions.

But the next day, he used the book to discuss some arithmetic problems with Qin Shao that he didn't quite understand.

Qin Shao flipped through the book, it was called "Nine Chapters of Arithmetic"

There are 264 mathematical problems in "Nine Chapters of Arithmetic", which are divided into nine chapters.

The content of the Qin Shao County Examination is the simplest, but there are actually some more complicated questions in it.

For example, Chapter 1 is Fangtian, which mainly talks about the calculation method of the area of ​​geometric figures, such as triangles, quadrilaterals, isosceles triangles, right-angled trapezoids, circles, sectors, etc.

The geometric figures learned in elementary school in the previous life are all there.

Learning this is because if you become a civil servant in land management, you can easily calculate the area of ​​the field, which is also quite practical.

In addition, there are four arithmetic operations of fractions, the greatest common divisor of the numerator and denominator, etc.

Chapter 2 is more practical, that is, how to convert grains and grains in proportion, which is more related to people's livelihood.

Chapter 3 is decay, which is the problem of proportional distribution, which is also very practical.

Chapter 4 is Shaoguang, that is, you already know the values ​​such as area and volume, how to find the length of one side, and the square root and cube.

Chapter 5 is commercial work, which is the calculation formula of earth and stone engineering and volume.

Chapter 6 loses, how to apportion taxes reasonably.

Chapter 7 profit and loss, that is the problem of calculating profit and loss.

Chapter 8 equation, which even mentions negative numbers.

Chapter 9 Pythagorean, also known as the Pythagorean theorem.

When I first started wishing the old man Qin Shao mathematics, I only asked him to do some questions and hand-written county test papers in previous years, but did not let him read this book.

When the old man Zhu asked himself to discuss the problems inside and let him finish reading this book, he was really amazed.

It doesn't mean how deep the content is. As a college student in the previous life, ordinary junior high school students can quickly master those things.

The reason is that people in previous lives have already studied it thoroughly!

What surprised Qin Shao was that in such a distant ancient time, these things had just begun to spread.

When he went to school in his previous life, he always thought that these things came very late.

Unexpectedly, the ancestors were so smart.

When the old man Zhu told him that this book had been in existence since the Warring States period, but it was only fully completed in the Han Dynasty, and he was no longer complacent about himself as a prophet of modern people!
Without the wisdom of our ancestors, what can modern people understand!

I wish the old man is good at writing poems and calligraphy, but he is not that strong in arithmetic to be honest.

Especially the numerator and denominator, it was a little difficult for him to understand. Qin Shao explained it to him with the method taught by his teacher in his previous life, and then he came up with a few questions to explain it to him, and then he gradually understood.

When he understood, he stood up and bowed down to Qin Shao!

"Master, what are you doing?"

Qin Shao stood up in a jerk, wishing the old man what kind of fun he was!

"If three of you are together, you must have my teacher! I call myself your teacher. When I explain it today, I know that my knowledge is shallow, and I am really not worthy to be your teacher."

Zhu Zhishan said sincerely.

"Master, you can, you already said that if three of you are together, then there must be my teacher! You forgot the last two sentences."

"Choose the good ones and follow them, and change the bad ones! What do you mean? That is to say, among the three, there must be my teacher. The reason is that everyone must have their own good side, and they are all worthy of your study. We just need to learn the good side of others and avoid the bad side!"

"No one is perfect! For example, although I may be good at arithmetic and can memorize books, my calligraphy is not as good as yours, I don't know how to write poems very much, and I don't have that much experience in scientific examinations. These are what I lack , so I need to learn from you, and you are also suitable to be my wife."

"Students worship you as a teacher today, just for the scientific examination. Since you are more experienced and knowledgeable than me in this field, you should continue to be my teacher! Of course, we can also learn from each other."

Qin Shao said sincerely.

I'm really worried that the old man Zhu won't teach himself if he can't think about it for a while.

To learn this thing, the teacher introduces the door, and the practice depends on the individual.

As one of the four talents, Zhu Zhishan's knowledge is beyond doubt.

The reason why he didn't go well in the scientific examination should actually have a lot to do with luck.

He was able to successfully pass the examinations as a scholar and a scholar, but he stopped at the general examination.

Although at the test level, elites from all over the country gather together, the exam is really difficult, but this ancient time does not want to be modern, there are many other subjects with fixed answers besides Chinese.

In ancient times, when it came to the test, many of them mainly relied on articles!
Whether an article is well written is just like whether a beauty is beautiful. Different people see beauty differently, with personal factors.

Of course, the performance of the scientific examination is also a large part.

But no matter what, I wish the old man taught himself, that is definitely enough!
"After your explanation, Zhu Mou is like enlightenment. It turns out that the words of Confucius can be explained in this way. In this case, I will reluctantly continue to be your teacher. Your talent will surpass me sooner or later. As long as you work hard, Chunwei will be on the gold list."

Zhu Zhishan said with a sigh.

Qin Shao heaved a sigh of relief.

"Master, the students don't plan to be able to participate in Chunwei, it's too time-consuming, I...I think... I can just pass the exam as a scholar!"
