"Ah, then I've already started eating."
"Who was so enthusiastic and gave you so many meal coupons?" Suddenly, his voice paused, "(*Jinling Yayan*) You slept at my house last night, and who unknowingly took the meal away from you? I'll give you the coupon. Anyway, you eat first. If we have any problems here, Daozu will tell us in advance. Daozu didn't say that it's okay. Anyway, if you don't eat, you won't get it. You eat yours, I will check it slowly. See you."
Zhu Xianfen hung up the phone.
【Tsk】
"Do you feel anything?"
【No. Brother, I want to sleep. I am not Qin Qiong or Yuchi Gong, standing guard like a door god for you. 】
"Hey~~What use do you have?"
[I’m already very useful when I’m awake, can’t you let me sleep a little longer? I'm still growing. 】
"Tsk, forget it. Anyway, Daozu didn't say anything. It's just fine. Let's eat and eat."
He put down the jade token.
"Are you okay?" Wen Yuan asked him next to him. Although it could be seen from his expression that there was no problem, he still asked.
"No problem, let's keep eating. Well, we have a treat today."
Lu Liang, who was opposite, glanced out the window - the scenery here is also very good. Not only can he see Mount Wutai, but he can also see the Yuejiang Tower, the Longjiang Navy Anchorage in Xiaguan, and Pukou on the other side of the river. Container ships coming and going from the port.
"Oh~~I'm a little embarrassed that you suddenly treated me to such a nice treat." Qi Yuan was a little embarrassed. She originally thought it was just a dinner party among classmates, and even eating at Lan Fang Pavilion wouldn't cost much. Unexpectedly, it directly reached the top of the popular food category - although it is still far from the top compared to business reception and government cuisine, this is already quite an exaggeration. It was so exaggerated that she didn't even know how to return the favor.
"Hey, just eat it, don't worry about it." Shangluo didn't know who invited him. No matter what, it’s eating anyway, and eating is always good.
"Okay." Qi Yuan could only nod. Come and eat anyway, let’s eat first and talk later.
Before the food was served, Shangluo was drinking tea when he suddenly remembered something.
"By the way, what's our schedule after the game?"
"After the game? Of course you will go back to class until the end of the year."
"So the semester isn't over yet?"
"Of course. The new semester starts in spring, not autumn. We still have to be classmates for half a year, and the results of the imperial examination will not be available until the winter solstice."
"Why the winter solstice?"
"Because the winter solstice is a year in the solar calendar, not the imperial calendar. Like the imperial court and many companies today, they calculate their fiscal years based on the winter solstice. So in ancient times, the winter solstice was called the beginning of the year. This is an old rule. . Because the solar terms are calculated according to the solar year, there must be 365 days between the two winter solstices. The imperial calendar is a lunisolar calendar, and there may not be 365 days in a year. Well, considering that you have stayed in the place where the giant baboons are showing their teeth for too long , help you add some common sense."
"I told you that the orangutans from Yangzhou are also there. Why did you turn into a baboon again? I told you that there are no wild animals there. But I really don't know."
"." Hearing this, Qi Yuan was stunned for a moment, "I've actually been worried about a question: Can you pass the scholar examination?"
"Yes, it should be possible."
"Wait a minute." Qi Yuan opened his crossbody bag and took out a booklet:
The dark blue cover of "A Scholar in Three Years and Successful Examination in Five Years" is a mathematics volume.
Qi Yuan flipped through the booklet, only to the first few pages, and handed it to Shangluo to look at the examples.
"Look at it. The scholar exam is the "National Benchmark Academic Proficiency Test". It is quite simple, and even the question types have not changed much. It is only for junior high school level. This high school level brochure only mentions it a little, and the main part is five years. Passed the test. But you should take a look. Do you know this math problem?"
Shangluo glanced at it:
There are 49 chickens and rabbits in total, with a total of 100 legs. How many chickens and rabbits are there?
[There are 48 chickens and 1 rabbit. ] Apollonia reported the answer.
"I don't need you to remind me! Are you despising me? This is common in elementary school, right?"
【Eh? It turns out you can, I thought you couldn’t. Tsk, tsk, tsk, that’s awesome. 】
"Why are you so weird?" He put the booklet down on the table: "Don't worry, monitor. You will know the answer at a glance."
"Yeah." Qi Yuan nodded, "As easy as you like. After all, it's just a 'National Benchmark' test. It's not that difficult. It's just a system of linear equations in two variables."
She took out her pencil and said, "Let's solve it."
"Here?"
"Anyway, it's okay to wait for the food to be served. Let me help you take a look."
"Tsk, I think this is contempt for me. You have to solve this kind of problem even though you are such an adult."
"Then you solve it. Write the steps clearly, try to write as long as possible, and keep the paper neat. Although one variable and two variables can be solved, both are correct. But the syllabus is a system of linear equations in two variables, so you should follow the two variables Solve it."
Shangluo took the pencil and began to solve the problem.
Solution: Suppose there are X rabbits and Y chickens
X+Y=49
Answer: There are 48 chickens and 1 rabbit.
Moreover, Shangluo did not write Arabic numerals. He knew that the Ming Dynasty used flower codes as the number system, and 49 was written as 〤〩.
Step by step, he solved the entire problem in a very standardized manner, and it didn't take even a minute.
However, when he raised his head, Qi Yuan across from him had already stood up and looked across half the table to look at her. Han Xingzhi on the left, Wen Yuan on the right also had their eyes widened, and even Lu Liang, who was farthest away, looked at her.
"You. What are you looking at me doing?"
"Ah" Han Xingzhi rubbed his eyes and confirmed: "Brother is really amazing, amazing."
"This is what you wrote." Wen Yuan looked at it for a long time. He had some words on his lips but didn't say them out.
"What kind of heavenly book are you writing?" Qi Yuan spoke out, "What is all this? Why did you write a lot of Latin XY? What is this cross? What is a word? ?”
"Ah, I set the chicken to be X, so let's set XYZ?"
"Let's say XYZ? Let's say heaven, earth and people, big brother! If the three are not enough, let's set up A, B and C. And what is this little 'ten'?"
"Ah" Shangluo was stunned, "This is '+', a plus sign."
"The plus sign is written like this, brother!"
Qi Yuan panicked. She took the pen and wrote "丄".
"This '丄' is the plus sign, and the minus sign is written as '丅'. You see clearly, this is not the T of the Latin alphabet. When the '丅' is written, it is pronounced '下', and the symbol is a minus sign. Understand Yet?"
"Ahhh."
"It's over!" Qi Yuan covered his head, "Who can understand what you write? Then how do you write the differential and integral symbols? You can't make up these strange symbols anymore, right?"
Shangluo's hands were shaking a little. It felt like he didn't realize he had missed a page until the last ten minutes of the exam.
He wrote the integral symbol ∫ and the differential symbol d.
Qi Yuan turned the book to her side. She was much calmer:
"Here, the integral is written as He and the differential is written as 彳, which are the radicals of product and differential. Where did you learn mathematics?"
"Ah, ah, ah, can you and I be saved?"
"There should be no problem with your mathematics level. But there is a big problem with your Chinese language level! Damn it, damn it. You have been writing with such ghost symbols from the beginning. The exam is only ten days away. I don't know if you can do it." Change it. By the way, didn’t you take math class at school? Ah! You slept during those days, but you didn’t come back later. Has no one noticed it before? "
"Ah, I've never written equations in front of others before. I've never written calculus before."
He did write it in front of Lao Shang, but Lao Shang never corrected him at all.
"But there should be hope, there is hope. Just wait, I'll get my brother's elementary school math textbook when I get back. You can read it from beginning to end. There should be hope. Start studying in the first grade of elementary school."
