Let me be a concubine? I turned to someone else's arms

After a while, the servants prepared the meal.

Xie Qi said, "Okay, elder brother, cousin Luo, let's put this matter aside for now, it's time to eat."

Then he smiled and said, "Cousin Luo, I asked someone to prepare turtle soup for you today."

Luo Qinrou smiled and nodded: "Thank you, third cousin."

Luo Qin enjoyed the meal very much, her mind was full of the opportunity Xie Yun gave her to show off. Her small shop would also be able to cooperate with noble families!

After the meal, the servants cleared the leftovers on the table. Xie Qi leaned on the table, touched her stomach, sat up again, and said to Luo Qin: "Cousin Luo, there is arithmetic class in the afternoon. Have you learned it?"

"Arithmetic?"

Luo Qin became interested, "I've learned this before."

I studied mathematics for so many years in my previous life, I wonder what mathematics is like in this era?

"That's right. If you haven't learned it, how can you do business and keep accounts?" Xie Qi understood, thought about it, and then said, "Oh, by the way, cousin Luo, there is an equestrian class tomorrow afternoon. Have you learned it?"

Luo Qin was stunned, "Equestrianism?"

Horse riding? No way, the Xie clan school also teaches this?

"For horsemanship, or more precisely, horse archery."

Mounted shooting?

A hint of embarrassment flashed across Luo Qin's eyes. She couldn't help twisting her handkerchief as she dropped her hands to her knees. She lowered her head slightly and said, "Actually, I only know the basics of riding a horse."

It was just a tiny insignificant thing. Her father and brother wanted her to be a gentle girl. The horse riding skills were just skipped so that Luo Qin would be able to ride a horse to save her life in case of an accident. That was all.

Hearing this, Xie Qi immediately showed interest. He smiled and said enthusiastically: "It doesn't matter if you know a little. Let my elder brother teach you tomorrow!"

"Is... this okay?" Luo Qin glanced at Xie Jun timidly, feeling a little uncomfortable.

After all, Xie Yun is such an elegant and noble person, how could he let her teach him how to ride a horse personally?

"Don't be afraid, he will be an excellent master!" Xie Qi raised his long eyebrows and winked mischievously at Xie Yun who was sitting on the couch on the other side, as if seeking his support.

However, Xie Yun just glanced at him indifferently without saying anything, but he did not refuse either.

Seeing this, Xie Qi propped up his arms and said loudly to Xie Yun: "If you don't say anything, then it will be considered that you agree!"

Xie Yun remained silent, neither responding nor refusing.

Xie Qi felt speechless for a moment, thinking to herself, well, what a tsundere!

Acknowledged the fact that Xie Yun had already agreed.

"Um..." Luo Qin broke the silence, "What other classes does Xie Clan have?"

She had always thought that it was just teaching various articles, such as poetry, songs, the Four Books and the Five Classics, and then the arts of music, chess, calligraphy and painting, but why did it feel like there was more than that?

Xie Yun, who was beside Luo Qin, spoke up at this time: "Including, but not limited to, the six arts of a gentleman."

Xie Qi also nodded, "Yes, we have to learn etiquette, music, archery, charioteering, calligraphy, mathematics, as well as poetry, songs, strategies and military books."

"So many?" Luo Qin was slightly surprised.

It sounds exhausting, okay?

Xie Qi shrugged, "It's OK. I've already finished my etiquette and imperial lessons."

The Six Arts of a Gentleman are the six basic talents of a gentleman and the essential qualities he must possess, including rites, music, archery, charioteering, calligraphy, and mathematics.

Li, or etiquette, includes various courtesies and ceremonies. In this era, people attached great importance to etiquette. One had to be proper in etiquette when attending any banquet. The children and grandchildren of the Xie family had learned it before they were ten years old.

Music refers to music, which not only includes the melody and performance of musical instruments, but also involves music theory and cultural connotations. The Xie clan school mainly teaches piano, flute, and Xiao, etc. In their class, they have finished teaching flute and Xiao, and are now learning piano.

Shooting refers to the technique of archery. The Xie clan school teaches archery and horse riding together.

"Yu" means driving. Driving is not only a practical skill, but also a symbol of identity and status. It is a skill that men need to learn, but girls don't need to.

Shu refers to calligraphy, and Shu refers to arithmetic, including mathematical knowledge and calculation skills.

These are mostly practical classes. Not only that, the Xie clan school also has cultural classes, where Master Xiao teaches poetry, songs and essays, and explains strategies and tactics. These classes occupy a dominant position, and in fact, most of them are cultural classes.

The Xie Clan School has several classes, with different age groups and naturally different course progress. Their class is an adult class.

The three of them took a short rest after dinner and went to school in the afternoon.

When Luo Qin entered the school, he found that there was an abacus on every desk in the school.

Don’t think that the ancients only knew addition, subtraction, multiplication and division when it comes to arithmetic. In fact, many more difficult problems have already been raised by people in this era.

In Luo Qin's original world, Liu Hui of the Wei and Jin Dynasties first proposed the idea of ​​limit in "Nine Chapters on the Mathematical Art", and used the method of dividing the circle to calculate the approximate value of pi to be 3.1416.

Liu Hui's method of dividing a circle is a method of approximating the area of ​​a circle by continuously increasing the number of sides of a regular polygon inscribed in the circle, thereby calculating pi.

After Liu Hui, Zu Chongzhi further improved the calculation accuracy of pi, calculating it to 7 decimal places, which is 3.

During the Wei and Jin Dynasties, mathematical monographs such as "Five Classics Mathematics" and "Records of Mathematics" appeared. Among them, "Sun Zi Mathematical Classic" solved the problem of chickens and rabbits in the same cage and proposed the famous Chinese remainder theorem.

Based on Liu Hui's work, Sun Zi's Mathematical Classic and Zhang Qiujian's Mathematical Classic optimized the methods of finding the greatest common divisor and the least common multiple, and pioneered the method of finding multiple solutions to a system of equations.

In addition, many mathematical theorems have been published, such as the definition of dimension number and progressive system.

When thinking of mathematics, Luo Qin couldn't help but think of the various geometric equations and functions from his previous life.

Hiss, it hurts, I just don't know if the Xie clan will learn to teach these? Don't do it!

The teacher of the afternoon arithmetic class was named Liu Shu, with the courtesy name Jizhi. He looked to be a man in his thirties, with sparse hair and a thin build.

As soon as Master Liu entered the room, he began to give arithmetic problems to the men and women, and said: "You should do these arithmetic problems this afternoon, and the answers will be announced in an hour."

Luo Qin's eyebrows jumped. It was enough. He had studied for nearly twenty years in his previous life. How come he had to go to class and practice questions after traveling through time?

Luo Qin took the question paper, read it from beginning to end, and then let out a breath.

Fortunately, they were all complex addition, subtraction, multiplication and division operations, as well as some linear equations of one variable or two variables, and the questions were written in classical Chinese, which were rather difficult to understand.

The girl secretly broke out in a cold sweat.

It’s, it’s okay… I can handle the junior high school knowledge, but it’s not the case with high school knowledge. It’s almost there, like I’ve drunk Meng Po soup.

After the students got the test paper and read the questions, they started to play with the abacus. Luo Qin also followed suit and fiddled with it a few times, then picked up the pen to calculate with Arabic numerals.

In fact, if you are proficient in using an abacus, it can be faster than pen and paper calculations. If you are good at using the abacus, you can even do multiple powers. But the problem is that Luo Qin is really not used to using this thing.

The school was completely silent, with only the clacking of abacuses by the students. Soon the sand clock showed that an hour had passed.

Master Liu read out the answers to each question, and then began to explain, which was similar to the math classes in later generations. Luo Qin felt depressed and drowsy after listening to him, but she still had to keep her posture graceful and kneel down, and finally made it until the end of the school.

On the carriage back to Luo Mansion after school, Luo Qin told Rufang: "Rufang, prepare a set of riding clothes for me tonight."

"Riding clothes?"

What does the girl want this for?

Hearing the question from the little girl next to him, Luo Qin said calmly: "There will be a horse riding and archery class tomorrow afternoon."

"The servant understands."
