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. p>
He didn't let that vixen Lin Sushuang succeed, and his precious daughter Rulan didn't 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. His daughter Rulan is obsessed with arithmetic problems for some unknown reason.
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 find out the details, which makes Wang Ruofu a little worried.
Wang Ruofu was actually similar to Ru Lan when he was a child. 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 syllabus and it would be useless to answer it.
Rulan wrinkled her nose, with a puzzled look on her face: "But my husband said, 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 had known that Ru Lan was talking about Mr. 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, to ask for advice. When he came back, he told Ru Lan exactly the same, 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 quickly!
When she returned to school after self-study in the evening, Ru Lan 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 tangled.
The reason why Ru Lan was suddenly 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 itching with hatred. p>
"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 housewife in the future.
!"
Ru Lan set her 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. Ru Lan'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. In addition to her mother Wang Ruofu, she also went to ask her second brother Sheng Changbai for advice.
Sheng Changbai was indeed a good at writing classics, but his attainments in arithmetic were only mediocre. After some calculations, Sheng Changbai regretfully said that he didn't know how to solve this question either.
Today, when she got to school, Ru Lan thought hard about 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 perspective, this is called learning from the barbarians and gaining skills to defeat the barbarians. Although Dazhou did not have this sentence, Rulan's mood at this time was not much different from the person who shouted this slogan.
Study with patience first, then slap you in the face!
After setting the basic line of struggle, Rulan no longer hesitated and stepped forward with her chest raised: "Little sir, I'm here to ask for advice!"
Seeing Ru Lan looking like she was ready to die, Wei Chen was confused. What kind of hysteria did this little girl have?
However, answering questions and resolving doubts was the job of Mr. Wei Chen. Wei Chen still stretched out his hand and said: "Bring me the question..."
"Thank you, little 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 title is as follows:
"Today, a total of 190 cows were bought by seven families, which was less than 330. Nine families paid 270 yen in total, with a surplus of 30. I asked the families, what is the price of the cows?"
When Wei Chen saw it for the first time, he felt a little confused. 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 one hundred and ninety-sevenths of the money, there will still be a shortfall of three hundred and thirty yuan. If each family contributes two hundred and seventy-ninths of the money, then there will be an excess of three hundred yuan.
Ten coins, how many are there in total and what is the price of cattle?
In this way, the question was very clear, and Wei Chen brushed down his ideas for solving the problem on the manuscript paper.
"The price of cattle is equal to 190/7 times the number of households plus 330, and it is also equal to 270/9 times the number of households minus 30. Therefore, 190/7 times the number of households plus 330
Ten equals two hundred and seven-ninths times the number of households minus thirty."
When Wei Chen wrote this, he yawned for a long time. 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 families 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 a calculation chip. 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 eye and two eyes?
Rulan secretly cursed.
However, although this person's words are a bit annoying, at least he seems 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 quite necessary to confuse the opponent and make the opponent relax their vigilance.
Rulan thought about it, 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 expression of reluctance, 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 fragrance of candied dates immediately filled his entire mouth.
"So sweet!"
Ru Lan was very happy to be praised by Wei Chen: "Little sir, can I ask you for advice on arithmetic from time to time?"
"That's natural."
Wei Chen smacked his lips 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?
