I heard that many bottles and cans were broken in Lin Qige, and Mo Lan and Lin Sushuang had a big fight. Wang Ruofu felt refreshed and comfortable for several days.
The vixen Lin Sushuang was not allowed to succeed, and his precious daughter Ru Lan did not have to leave him. This was the most satisfying result for Wang Ruofu.
Although Liu Yatou got the better of him in the end, Wang Ruofu was happy from the bottom of his heart as long as he saw Lin Sushuang defeated.
However, Wang Ruofu has been troubled recently. Daughter Ru Lan didn't know what evil she had possessed, but she became obsessed with arithmetic problems.
It is said that it is a good thing for his daughter to study diligently, and Wang Ruofu should be happy, but the problem is that Ru Lan always chases her with those questions to get to the bottom of it, which makes Wang Ruofu a little worried.
When Wang Ruofu was a child, he was actually similar to Ru Lan. He also dozed off in class. In terms of academic performance, he was not much better than Ru Lan.
At the beginning, Wang Ruofu could still rely on his past accumulation to explain to Ru Lan.
But as the questions Ru Lan asked became more and more difficult, Wang Ruofu soon ran out of skills and could only tell his daughter seriously that this question was beyond the scope and it would be useless to answer it.
Ru Lan wrinkled her nose and looked confused: "But the husband said that this is all knowledge that a matron must learn!"
Wang Ruofu suddenly felt ashamed of being exposed by his daughter, and he became very embarrassed at that time.
She subconsciously thought that the gentleman Ru Lan was talking about was Zhuang Jun. If she knew that Ru Lan was talking about Wei Chen, she might not be so panicked.
In order to maintain his mother's dignity in front of his daughter, Wang Ruofu hurriedly escaped and secretly went to Liu's mother, who was proficient in arithmetic, for advice. When he came back, he told Ru Lan exactly what he wanted, and then he managed to get through.
Two days later, Wang Ruofu couldn't understand the questions Ru Lan brought to her, and even Liu's mother was drained.
Wang Ruofu was forced to have a showdown with his daughter: Your mother is almost driven crazy by you, you'd better hire someone else as soon as possible!
When she returned to school after self-study in the evening, Rulan looked at the questions on the table, then raised her head and glanced at Wei Chen who was concentrating on the papers in the hall, feeling very entangled.
The reason why Ru Lan suddenly became obsessed with arithmetic problems was simply because she was offended by Wei Chen's words that day. Thinking of the scene where Wei Chen pretended to be a gentleman and taught her a lesson, Ru Lan felt itchy with hatred.
"Isn't it just a few arithmetic problems, Wei Xingyun, just wait for me, I have to do them all, and then slap the problem sheet hard on your face, telling you that I, Sheng Rulan, will definitely be a good mother-in-law in the future. !”
Ru Lan made great ambitions and quickly started taking action, starting with the three arithmetic problems assigned by Zhuang Jun every day.
However, ideals are full and reality is skinny. Rulan's "face-slapping plan" was completely stuck after only five days of implementation.
She thought about this question all night last night and had no clue. Apart from her mother Wang Ruofu, she also went to consult her second brother Sheng Changbai.
Sheng Changbai was indeed an expert in Jingyi articles, but his attainments in arithmetic were only mediocre. After some calculations, Sheng Changbai regretfully said that he didn't know how to solve this problem either.
Today, when she arrived at school, Ru Lan pondered over the topic for a long time, but still couldn't come up with a solution.
After hesitating for a long time, Ru Lan finally decided to put aside her dignity and ask Wei Chen for advice.
Think about it from another way, this is called learning from the foreigners and developing skills to defeat the foreigners. Although Dazhou did not have this sentence, Rulan's mood at this time was not much different from the person who shouted this slogan.
Be patient and learn first, then get slapped in the face!
After deciding on the basic line of struggle, Rulan no longer hesitated and stepped forward with her chest raised: "Little sir, let me ask for advice!"
Seeing Ru Lan looking like she was about to sacrifice herself, Wei Chen felt confused. What kind of hysteria did this little girl have?
However, answering questions and resolving doubts is the job of Mr. Wei Chen. Wei Chen still stretched out his hand and said: "Bring me the question..."
"Thank you, young sir."
Ru Lan presented the manuscript paper with a smile on her face.
Wei Chen took it and took a look. It turned out to be the art of surplus and deficiency. The specific topic is as follows:
"Today, we bought a total of cattle. Seven families paid a total of 190, which was less than 330. Nine families paid a total of 270, a surplus of 30. I want to ask how many families there are, and what is the price of the cattle?"
Wei Chen felt a little confused when he first read it. After reading the question again, he quickly realized that the question was expressed in a somewhat mysterious way and it was easy to misunderstand the meaning of the question. In fact, it was a simple quadratic equation of one variable. Even elementary school students know it!
But speaking of it, Ru Lan's age does seem to be not much older than the elementary school student Wei Chen was in his previous life.
Thinking of this, Wei Chen raised his head and glanced at Ru Lan in front of him. Ru Lan quickly lowered his head as if he was listening respectfully. Wei Chen shook his head and returned his attention to the topic.
First of all, Wei Chen changed the way of expressing the question to make it easier for Ru Lan to understand.
Now many families are discussing buying cattle together. If each family contributes 190/7 of the money, there will still be a shortfall of 330 yuan. If each family contributes 270/9 of the money, then there will be 330 yuan more. Ten cents, how many houses are there in total and what is the price of cattle?
In this way, the question was very clear. Wei Chen brushed his pen on the manuscript paper and wrote down his ideas for solving the problem.
"The price of cattle is equal to 190/7 multiplied by the number of households plus 330, and is equal to 270/9 times the number of households minus 30. Therefore, 190/7 multiplied by the number of households plus 330 Ten is equal to two hundred and seven-ninths times the number of households minus thirty.”
Wei Chen yawned long after writing this, and Ru Lan quickly held up her calculation chips and handed them over: "Little sir, do the calculations."
"No need." Wei Chen waved his hand and did a quick mental calculation. After a while, he picked up his pen and continued to write: "Answer, the number of households is one hundred and twenty-six, and the price of the cattle is three thousand seven hundred and fifty."
Ru Lan followed the formula listed by Wei Chen and calculated it again with the arithmetic chips. After fiddling with it for a long time, she finally figured out the answer.
The result was compared with Wei Chen's mental arithmetic answer, and it was exactly the same. Ru Lan was stunned: "Sir, you just took a look at it and figured it out?"
"That's not the case. I should have taken a second look." Wei Chen replied seriously.
Is there any difference between one look and two looks?
Ru Lan secretly cursed.
However, although this person's words are a bit annoying, at least he seems to be quite pleasing to the eye, and he is also very patient in teaching students...
Thinking of this, Ru Lan couldn't help but blush slightly, shook her head to stop her random thoughts, and remained firm on the basic line of "slapping Wei Chen in the face".
However, before that, it is also necessary to confuse the opponent and make the opponent relax their vigilance.
With a thought in mind, Rulan returned to her seat, took out a handkerchief from her book bag, opened it and handed it to Wei Chen: "This is candied dates stewed with glutinous rice. Please give me a compliment, sir."
Looking at Ru Lan's reluctant expression, Wei Chen couldn't help but feel amused: "Is this what you like to eat?"
"I eat a lot on weekdays, and I'm almost tired of it." Ru Lan was stiff-mouthed and said with some expectation: "This is what I want, little sir, please try it."
Wei Chen was not polite, took the candied dates and threw them into his mouth. The sweet aroma of candied dates immediately filled his entire mouth.
"So sweet!"
Ru Lan was very happy to receive Wei Chen's praise: "Little sir, can I ask you for advice on arithmetic from time to time?"
"That's natural."
Wei Chen smashed his mouth and had endless aftertaste.
However, why do I always feel that in addition to the sweet aroma of the food itself, there is also a unique fragrance of a girl?
