"Xiao Lu, what kind of holy book are these? Why can't I understand a single question?" Yan Yue looked at the real questions with a frown on his face and complained endlessly.
You must know that Yan Yue has been tinkering back and forth in the inn room with these so-called real test papers for several hours.
But looking at the confused look on his face, you knew that he didn't remember much at all.
"What can't you understand?" Yu Tianlu asked, "I don't think these questions are difficult?"
"Xiao Lu, do you think these questions are not difficult?" Yan Yue immediately exploded, "Look at this question: An elephant master uses the power of elephant transformation to conjure many rabbits and chickens, and then the total number of rabbits and chickens' heads is 39 heads, 146 legs. Ask the elephant chemist how many rabbits and chickens he conjured. I’m not a god? How do I know? I know these rabbits and chickens are quite delicious..."
After hearing this, Yu Tianlu almost fainted.
"Ayue, why are you thinking about eating? This is just a simple chicken and rabbit problem. It's not so scary, right?" Yu Tianlu said nonchalantly.
"A chicken and a rabbit in the same cage, what is this? Is it also from your original world?"
"That's right, even ordinary primary school students can solve it here."
"Then give me a try."
"Isn't this just a system of linear equations of two variables." After saying that, Yu Tianlu took out a piece of white paper and wrote the formula on the white paper using the power of imagery.
"Let the number of rabbits be X, and let the number of chickens be Y."
"What are these big forks and branches?"
"These are X and Y, also called unknown numbers. Just think of them as symbols."
"This symbol looks weird. It looks like the evil talisman my mother bought for the Chinese New Year." Yan Yue complained coldly.
"Don't worry about your own details, just follow my formula."
After saying that, Yu Tianlu soon solved the problem of chicken and rabbit in the same cage using the system of linear equations of two variables in his previous life.
"...Finally we can find out that the number of rabbits is 34 and the number of chickens is 5. How about simplicity?" Yu Tianlu looked at Yan Yuedao with a sense of accomplishment.
"Well... Xiaolu, is there a possibility that you don't have the talent to teach?"
"What? I don't have the talent to teach?"
Yan Yue's words were like a sledgehammer, hitting Yu Tianlu's chest directly.
At this moment, he also remembered his experience as a part-time tutor in his previous life.
This Yu Tianlu was a university master in his previous life, and he could master any subject at his fingertips. High scores in the college entrance examination are the best example of this.
It's just that his confidence in his subject was completely destroyed when he became a tutor.
At that time, under the aura of being the top scorer in the college entrance examination, he went to work as a tutor for a junior high school student. Logically speaking, it is not easy for someone who tops the college entrance examination to teach junior high school students.
But at that time, although Yu Tianlu was good at solving questions, he was not very good at teaching.
In his opinion, those simple junior high school questions can be solved with mechanical memory using only hands. But when he actually teaches his students, no matter how many methods he uses, he can't make his students enlightened.
"Teacher, we haven't taught this concept yet?"
"Teacher, have we never seen this formula before?"
"Teacher, I can't keep up with your thinking at all!"
After complaining, not to mention that the tutoring experience did not give Yu Tianlu a feeling of mutual benefit from teaching, and the grades of many of his students actually declined.
So Yu Tianlu's tutoring career soon ended in a muddle.
At this moment, seeing Yan Yue still raising the same questions as those students back then, Yu Tianlu finally understood the principle of teaching students in accordance with their aptitude.
Seeing Yu Tianlu standing there numbly, Yan Yue thought that his words had damaged Yu Tianlu's self-confidence.
"Xiao Lu, you are just talking nonsense, don't take it to heart!" Yan Yue quickly blamed himself, "Can't I memorize these questions even if I try hard?"
"No, Ayue, I think what you said makes sense." Yu Tianlu said calmly, "It seems that no matter whether you use rote memorization or other conventional methods, there is no way for you to pass the Royal Academy in a short time. entrance exam."
"Then Xiaolu, are you ready to give up on me?" Yan Yue said with a sad face.
"Who said I was going to give up on you!" Yu Tianlu laughed loudly, "I was thinking of another way that you can easily accept."
"How to make me accept it? What method?"
"I see your interest is not in eating? Just think of the questions as food."
"Imagine it as food?"
"For example, this question: Suppose a group of elephantizers came to the competition arena and lined up in a hundred rows. There was 1 elephantizer in the first row, 2 in the second row, 3 in the third row, and so on. Finally, There are 100 elephant masters in the 100th row. How many elephant masters are there in the arena?"
"How to do this question?" Yan Yue was confused again.
"You can think of the elephantizer as the strawberry on the cake." Yu Tianlu said with a smile.
"Strawberries on the cake?"
"You can think of this question as a hundred-layered strawberry cake."
"A hundred layers of strawberry cake? Then I can have a full meal!" Yan Yue let out a sigh of relief.
"Ah drink!" Yu Tianlu coughed, "Don't make a cross, I'm teaching you how to solve problems!"
"Sorry, Xiaolu, please continue."
"For this question, you can imagine that there is one strawberry on the first layer of cake, two strawberries on the second layer, and so on, and ten strawberries on the tenth layer. How many can you eat in total?"
"If it's the tenth floor..." Yan Yue thought for a moment and quickly gave his answer, "There are fifty-five!"
"Sure enough! You really got it right!" Yu Tianlu said happily.
In fact, after living with Yan Yue for so many years, Yu Tianlu was very accurate about Yan Yue.
Every time the two of them go out to eat, Yan Yue often eats Haisei like a gulp. But in the end, if you asked him what he had eaten, he would be able to tell you everything in detail.
As big as a few kilograms of clams, as small as a few jelly beans. Yan Yue's ability to calculate and remember food is several times higher than that of ordinary people.
"What if the scope is expanded to 100 floors?" Yu Tianlu continued to ask.
"Xiao Lu, please wait a moment, I will calculate carefully..." With such a large amount of data, Yan Yue still needs a little time. However, it didn’t take long before Yan Yue still gave the correct answer of “5050”.
"Xiao Lu, I shouldn't have made a mistake in my calculation, right?" Yan Yue asked tentatively.
"The calculation is correct. It seems that your mental arithmetic ability for food is so good!" Yu Tianlu said with a smile, "But there is actually a convenient algorithm for this."
"Convenient algorithm?"
At this moment, Yu Tianlu had already used his power to create a virtual shadow of a hundred layers of strawberry cake in the room.
"Ayue, look, is the number of strawberries in this layer of cake plus the 100th layer of cake 101?" Yu Tianlu said as he pulled out the first layer of cake and the 100th layer of cake in the space and put them together.
"Yes, it is indeed."
"Then the number of strawberries on the second + 99th floor is also 101! Then the third + 98th floor is also 101."
"Xiao Lu, I understand. The number of strawberries on the last 50th and 51st floors is also 101. In fact, the number of strawberries is 101×50, which is 5050!" Yan Yue, who had become enlightened, immediately told the answer.
"You're a teachable boy!" Yu Tianlu nodded happily.
Next, Yu Tianlu took out the real questions and used the same method to transform the boring real questions into gourmet questions. In this way, it not only increased Yan Yue's interest, but also greatly improved the efficiency of review.
After a whole day, Yan Yue's improvement was simply a geometric progression for him.
"A Yue, you really have potential!" Even Yu Tianlu marveled at Yan Yue's learning ability, "If you take the exam now, at least passing the exam will not be a problem."
"Ah! Why did you pass the exam?" Yan Yue was a little discouraged, "I heard that the entrance exam score must be above 80 points!"
"Ayue, before you go through the review process, it would be good if you can get a ten point in the exam. You must know that this step of yours is already a big step for other students." Yu Tianlu said with a smile, "And there is only one month left. Is it time? Just follow my ideas and I’m sure you can pass the entrance exam.”
"Really? That's great!" Yan Yue held Yu Tianlu's hand, looking very happy, "I can be with Xiaolu again. But Xiaolu, there is something before that."
"What's going on?"
"Gululu!" Yan Yue's stomach drummed unconsciously.
"Sorry, you, a big eater, haven't eaten anything at the end of the day!" Yu Tianlu said with a smile, "I'll go get you food right now!"
Soon Yu Tianlu brought a large bag of black bread and placed it in front of Yan Yue.
Yan Yue was obviously disappointed when he saw these dark breads.
"Xiao Lu, why do we only have black bread to eat?" Yan Yue said, "Isn't it the food manager when we stay at Ma's Inn?"
"Tch, isn't Ayue blaming you?" Yu Tianlu said angrily.
"Blame me? Why blame me again?"
"Originally, Ma's Inn is in charge of food until the end of the exam. Who told you to eat at the buffet in someone else's store until closing on the first day? No one can stand it!" Yu Tianlu said helplessly.
In fact, the innkeeper had already greeted Yu Tianlu before.
"Master Yu, although Master Ma also wrote a letter instructing us to entertain you two well, Master Yan's appetite is really... This is almost enough for more than thirty people... we It's a small business in the provincial capital, so why don't you ask for your support?" said the owner of the inn, Shopkeeper Feng.
"Shopkeeper Feng is really sorry for causing you trouble." Yu Tianlu apologized, "That's it! Just follow the original meal plan for each person, and let me arrange the food!"
"Thank you so much, Master Yu! Thank you so much, Master Yu!"
"Ayue, you eat the food expenses of thirty people in one meal, who can withstand this!" Yu Tianlu said, "We are not familiar with the place when we come to the provincial capital, and there are still many places where we need shopkeeper Feng's help, so Please calm down a little!"
"Okay! Okay!" Yan Yue said, he could only nibble on the black bread, "Xiao Lu, don't tell me that although this black bread tastes light, it tastes very layered, even when you swallow it. It’s an endless aftertaste!”
"Not only is it unforgettable, but it's also very nutritious. The food I prepared for us, the duo who were rushing to take the exam, paid great attention to the nutritional mix." Yu Tianlu said with a smile.
Even though these black breads look ordinary, Yu Tianlu asked shopkeeper Feng to help prepare them.
Yu Tianlu made these nutritious breads in the most economical way according to the ingredient ratios of those nutritious breads in his previous life. It can completely ensure the energy and protein required by the human body for a day.
So before the exam, these brown bread became the staple food of the two friends.
Fortunately, Yan Yue has a big appetite, but he is not too picky about the ingredients. As long as he can eat enough, he is satisfied.
