Ming Dynasty and New Rome and Infinite Magic Machine

Chapter 239

"Ah, then I've already started eating."

"Who is so enthusiastic and gave you so many meal coupons." Suddenly, his voice paused, "(*Jinling Yayan*) You slept at my house last night, who secretly took the meal The coupon is in your bag. Anyway, you eat it first. If we have any problems here, Daozu will tell us in advance. Daozu didn’t say anything, it’s okay, anyway, if you don’t eat for nothing, you eat yours, I’ll check it out slowly. See you."

Zhu Xianxi hung up the phone.

【tsk】

"How do you feel?"

【No.Brother, I want to sleep, I am not Qin Qiong and Yu Chigong standing guard for you like a door god. 】

"Hey~~ what do you want?"

[It's already 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, so he's fine, let's eat and eat."

He put down the jade tablet.

"Are you okay?" Wen Yuan next to him asked him.Although it could be seen from the look that there was no problem, he still asked.

"No problem, let's continue to eat. Well, there is a treat today."

Lu Liang on the opposite side glanced out of the window - the scenery here is also very good, not only can you see Wutai Mountain, but you can also see Yuejiang Tower, the Longjiang Navy Anchorage in Xiaguan, and Pukou on the other side of the river Container ships coming in and out of the port.

"Oh~~ You suddenly invited me to eat so well, I'm a little embarrassed." Qi Yuan was a little embarrassed.She originally thought that it was just going out for dinner among classmates, even if she went to Lanfang Pavilion to eat, it would not cost much money.I didn't expect to directly reach the top of the public food segment - although it is far from the top compared with business reception and official cuisine, this is already quite an exaggeration.It was so exaggerated that she didn't know how to return the gift.

"Hey, just eat it, don't worry about it." Shang Luo didn't know who invited him.Whatever it is, it's eating anyway, and eating is always good.

"Okay." Qi Yuan could only nod his head.Anyway, come to eat, eat first and then talk.

Before the food was served, Shang Luo was drinking tea when he suddenly remembered something.

"By the way, what's our schedule after the game?"

"After the game? Of course I went 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 have to be classmates for half a year, and the results of the imperial examinations will not come out until the winter solstice."

"Why is it the winter solstice?"

"Because the winter solstice is a year of the solar calendar, not a year of the imperial calendar. Like the imperial court, and many companies now, they calculate their fiscal year according to the winter solstice. So in ancient times, the winter solstice was called the beginning of the year. This is an old rule. Yes. 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 yin and yang calendar, and there may not be 365 days in a year. Well, considering that you have stayed too long in the place where the big baboon bared its teeth , to help you supplement your common sense."

"I said that the orangutans in Yangzhou are also there. Why did they become baboons again? I said that there are no wild animals there. But I really don't know."

"." Hearing this, Qi Yuan was stunned for a moment, "Actually, I have always been worried about a question: Can you pass the talent test?"

"Yes, it should be possible."

"Wait." Qi Yuan opened his messenger bag and took out a booklet:
The dark blue cover of "Three-Year Scholars and Five-Year Entrance Examination", this is the Mathematics Fascicle.

Qi Yuan flipped through the booklet, only the first few pages, and handed it over to Shangluo to look at the sample questions.

"You, take a look. The Xiucai Exam is the "National Benchmark Academic Ability Test". Zhongju. However, you should take a look. Do you know this math problem?"

Shang Luo took a glance:
There are 49 chickens and rabbits, with a total of 100 legs. How many chickens and rabbits are there?

[There are 48 chickens and 1 rabbit. ] Apollonia reported the answer.

"Don't remind me! Are you despising me? This is common in elementary school!"

【Eh?So you will, I thought you would not.Tsk tsk tsk, it's amazing. 】

"Why are you acting weird." He put the booklet down on the table: "Don't worry, monitor. You'll know the answer at a glance."

"Yeah." Qi Yuan nodded, "It's good if you think it's simple. After all, it's just a 'National Benchmark' test, so it won't be too difficult. It's just a linear equation in two variables."

She took out a pencil: "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 it's a contempt for me, and I have to solve this kind of problem at such an adult."

"Then you solve it. Write the steps clearly, try to write as long as possible, and keep the paper clean. Although one and two variables can be solved, both are correct. But the syllabus is a system of linear equations in two variables, so you can follow the two variables. Solve it."

Shang Luo took the pencil and started 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 didn't write Arabic numerals. He knew that Daming used Huaji as the number system here, and 49 was written as 〤〩.

Step by step, he solved the whole problem in a standardized manner, very standardized, and it took no more than one minute before and after.

However, when she raised her head, Qi Yuan on the opposite side had already stood up and looked at her across half of the table. Han Xingzhi on the left and Wen Yuan on the right also widened their eyes, and even Lu Liang, who was farthest away, looked at her.
"You... what do you see me doing?"

"Ah..." Han Xingzhi rubbed his eyes and confirmed it: "Brother is really astonished as a heavenly man, shocked as a heavenly man."

"This is what you wrote." Wen Yuan read it for a long time, and he had some words on his lips, but didn't say them.

"What kind of bible is this you wrote?" Qi Yuan spoke out, "What is all this? Why did you write a lot of Latin XY on it? What is this cross? What is one word? ?”

"Ah this. I set the chicken to be X, so let's say XYZ?"

"Set XYZ? Let heaven, earth and man, big brother! Tian yuan, earth yuan, and people yuan, if three are not enough, then set A, B, and C. And what is this little 'ten'?"

"Ah." Shang Luo was stunned, "This is '+', a plus sign."

"The plus sign says so, brother!"

Qi Yuan panicked. She took a pen and wrote "丄".

"This '丄' is the plus sign, and the other minus sign is written as '丅'. You can see clearly that this is not the Latin letter T. This '丅' is pronounced as '下' when it is used as a character, and the symbol is a minus sign. I understand. Yet?"

"Ah."

"It's over!" Qi Yuan covered his head, "Who can understand what you wrote! Then how do you write the differential and integral symbols? You can't make up some strange symbols anymore, right?"

Shangluo's hands trembled a little. It felt like he didn't realize he had read a page until the last 10 minutes of the exam.

Integral symbol ∫, differential symbol d, he wrote it.

Qi Yuan turned the brochure to her side, and she was much calmer:

"In our place, the integral is written as Wo, and the differential is written as 彳, which are the radicals of the two characters of product and micro. Where did you learn mathematics?"

"Ah, ah, can you and I still be saved?"

"There should be no problem with your math level. But your Chinese level has a big problem! It's over, you've been writing with ghost symbols like that from the beginning, and you have an exam in ten days. I don't even know if you can do it." Change it. By the way, didn’t you have math class at school? Ah! You slept for a few days, and you didn’t come later. Has no one noticed before?”

"Ah, I haven't written equations in front of others before. I haven't written calculus."

He did write it in front of the old businessman, but the old businessman never corrected him.

"But there should be help, there is still help. Wait, I will bring my brother's elementary school math textbook when you get back. You can read it from cover to cover, and there should be help. Start from the first grade of elementary school."
