"I said Xiaolu, what kind of books are these? Why can't I understand a single question? Yan Yue looked sad and complained.

You must know that this Yan Yue has been tinkering back and forth in the room of this inn for a few hours with these so-called real question books.

But looking at his dazed face, I knew that I didn't remember much at all.

"What don't you understand?" Yu Tianlu asked, "I don't think these questions are difficult?" ”

"Xiaolu, you call these topics not difficult?" Yan Yue immediately fried the pot, "Look at this question: an elephant master uses the power of imagery to conjure many rabbits and chickens, and then the rabbit and chicken heads add up to 39 heads and 146 legs. Ask the Iconizer to conjure up a few rabbits and chickens. Am I not a god? How do I know? I knew the rabbit and the chicken were delicious......"

Yu Tianlu almost fainted after hearing this.

"I said Ah Yue, why are you thinking about eating in your head? It's just a simple chicken-rabbit cage problem, and it's not so scary, is it? Yu Tianlu said nonchalantly.

"Chickens and rabbits in the same cage, what is this? Is it also from your original world? ”

"That's right, even ordinary elementary school students can solve it in our place."

"Then you can give me a try."

"It's not just a system of binary equations." After that, Yu Tianlu directly took out a blank piece of paper, and then used the power of visualization to write the formula on the white paper.

"Let the number of rabbits be X and the number of chickens be Y."

"What are these forks and branches?"

"These are X and Y, also known as unknowns. You can think of them as symbols. ”

"This symbol looks weird, it's like a talisman that my mother bought for the New Year." Yan Yue complained coldly.

"Don't worry about your own details, you just look at the formula I arrange."

After speaking, Yu Tianlu soon used the binary equations of his previous life to solve the problem of chickens and rabbits in the same cage.

“...... In the end, we can find that the number of rabbits is 34 and the number of chickens is 5. How simple is it? Yu Tianlu looked at Yan Yuedao with a sense of accomplishment.

"Well...... Is it possible that Xiaolu doesn't have the talent to teach? ”

"What? I don't have the talent to teach? ”

Yan Yue's words were like a sledgehammer, directly hitting Yu Tianlu's chest.

At this moment, he also remembered his experience as a part-time tutor in his previous life.

This Yu Tianlu was a university bully in his previous life, and no matter what discipline he had, he was at his fingertips. The high scores in the college entrance examination are the best example of this.

It's just that his self-confidence in his subjects was completely destroyed by the time he became a tutor.

At that time, he went to a junior high school student's home as a tutor with the halo of the top student in the college entrance examination. It stands to reason that it is not easy for the top student in the college entrance examination to teach junior high school students.

But at that time, although Yu Tianlu was good at doing questions, he was not very good at teaching.

In his opinion, those simple junior high school problems can be solved with the mechanical memory of his hands. But when he really teaches his own students, no matter how he tries them, he can't make them enlightened.

"Teacher, we haven't taught this concept yet?"

"Teacher, we've never seen this formula before?"

"I said, teacher, I can't keep up with your train of thought at all!"

After complaining, not to mention that the tutoring experience did not make Yu Tianlu feel like teaching and learning together, many of the students he taught had their grades declining.

So soon Yu Tianlu's tutoring career ended in a blur.

At this moment, seeing that Yan Yue still raised the same questions as those students back then, Yu Tianlu finally understood the truth of teaching students according to their aptitude.

Seeing Yu Tianlu standing there blankly, Yan Yue thought that his words had hit Yu Tianlu's self-confidence.

"Xiaolu, you are talking nonsense, don't take it to heart!" Yan Yue hurriedly blamed himself and said, "Can't I memorize these topics hard?" ”

"No, Ah Yue, I think you have a point." 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 entrance exam of the Royal Academy in a short time. ”

"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, "I'm trying to use another method that can be easily accepted by you. ”

"Let me accept the method? What method? ”

"I see your hobby is just eating, isn't it? You just have to think of the topic as food. ”

"Think of it as food?"

Let's say this question: Let's say that a group of elephantizers came to the arena and lined up in a hundred rows. There is 1 Iconizer in the first row, 2 in the second row, 3 in the third row, and so on, and finally there are 100 Iconizers in the hundredth row. Q: How many Iconizers are there in the arena? ”

"How do you do this?" Yan Yue was confused again.

"You can think of the Elephant Maker as a strawberry on a cake." Yu Tianlu said with a smile.

"Strawberries on the cake?"

"You can think of this as a 100-story strawberry cake."

"A hundred layers of strawberry cake? Then I can have a full meal! Yan Yue listened and let out a sigh of anger.

"Ahh Yu Tianlu coughed, "Don't cross it, it's teaching you to solve the problem!" ”

"I'm sorry, Xiaolu, you continue."

"You can think of this as having one strawberry on the first layer of cake, two strawberries on the second layer, ten strawberries on the tenth layer, and so on. How many can you eat? ”

"Ten layers of words......" Yan Yue thought for a while and quickly gave his own answer, "There are fifty-five!" ”

"Sure enough! I've got you right! Yu Tianlu said happily.

In fact, after living with Yan Yue for so many years, Yu Tianlu is still very accurate in handling Yan Yue.

Every time the two of them went out to eat, don't look at Yan Yue's frequent devouring of seafood. But when you finally ask him what he ate, he will be able to tell you everything.

As big as a few pounds of clams, as small as how many jelly beans you ate. For food calculation and memory, Yan Yue surpassed the ordinary number of times.

"What if we expand the range to 100 floors?" Yu Tianlu continued to ask.

"Xiao Lu, you wait a while, I'll calculate it carefully......" With such a large amount of data, Yan Yue still needs a little time. However, it didn't take too long for Yan Yue to give the correct answer of "5050".

"Xiaolu, I shouldn't have miscalculated!" Yan Yue asked tentatively.

"It's not wrong, it looks like you're so good at mental arithmetic about food!" Yu Tianlu smiled, "But this actually has a convenient algorithm. ”

"Convenient algorithm?"

At this moment, Yu Tianlu had already used the power of imagery to create a phantom of a hundred-layer strawberry cake in the room.

"Ah Yue, look, is the number of strawberries in this layer of cake plus the 100th layer cake 101?" Yu Tianlu said as he pulled out the first layer of cake and the 100th layer cake in the space and put them together.

"Yes, indeed."

"Then the number of strawberries in the second layer + 99th layer is also 101! Then the third layer + the 98th layer is also 101. ”

"Xiao Lu, I know, the number of strawberries in the last 50 layers + 51 layers is also 101. In fact, the number of strawberries is 101×50, which is 5050! The enlightened Yan Yue immediately said the answer.

"The child is teachable!" Yu Tianlu nodded with satisfaction.

Next, Yu Tianlu took out the real questions and used the same method to transform the boring real questions into food questions. In this way, it not only improved Yan Yue's interest, but also greatly improved the efficiency of review.

After a whole day, Yan Yue's ascension was simply a geometric progression for him.

"Ah Yue, you really have potential!" Even Yu Tianlu was amazed by Yan Yue's learning ability, "If you take the test now, at least it won't be a problem to pass the test." ”

"Ahh Why is this a pass? Yan Yue was a little discouraged, "I heard that the score of this entrance exam must be above 80 points!" ”

"Ah Yue, before you go through the review, it would be good if you could get ten points. You must know that this step of yours is already a big step for other students. Yu Tianlu said with a smile, "And isn't there another month?" Just follow my train of thought and make sure you can pass the entrance exam. ”

"Really? That's great! Yan Yue held Yu Tianlu's hand and looked elated, "I can be with Xiao Lu again." But Xiaolu, there is something before that. ”

"What's the matter?"

"Gollum!" Yan Yue's stomach unconsciously drummed.

"I'm sorry, you haven't eaten yet!" Yu Tianlu said with a smile, "I'll go get you food!" ”

Soon, Yu Tianlu brought a large bag of black bread and put it in front of Yan Yue.

Seeing these black breads, Yan Yue was obviously a little disappointed.

"I said Xiaolu, why do we only have black bread to eat?" Yan Yue said, "Aren't we in charge of food when we live in the Majia Inn?" ”

"Cut, isn't Ayue blaming you?" Yu Tianlu said angrily.

"Blame me? Why do you blame me for this? ”

"Originally, the Majia Inn was in charge of the food until the end of the exam, who told you to eat self-service in someone's store on the first day until it closed, in other words, no one can stand it!" Yu Tianlu said helplessly.

In fact, the innkeeper had already greeted Yu Tianlu before.

"Young Master Yu, although Master Ma also wrote a letter instructing us to treat the two of you well, but this Young Master Yan's appetite is really ...... That's almost the amount of food for more than 30 people...... We are also a small business in the provincial capital, and we invite the two of you to raise your hands! The owner of the inn, Mr. Feng, said.

"Shopkeeper Feng is really sorry to cause you trouble." Yu Tianlu said apologetically, "That's it! You just follow the original meal standard for each person, and let me arrange what the food is! ”

"Thank you, Young Master Yu! Thank you Young Master Yu! ”

"Ah Yue, you ate the food expenses of thirty people in one meal, who can withstand this!" Yu Tianlu said, "We are not familiar with the place where we came to the provincial capital, and there are still many places where we need the help of Shopkeeper Feng, so you should be a little more restrained!" ”

"Alright! All right! Yan Yue said, he could only nibble on these black breads at the same time, "Xiao Lu, don't say that although this black bread tastes light, it tastes very layered, and it has an endless aftertaste when swallowed in the stomach!" ”

"Not only is it delicious, but it's also very nutritious. The food I prepared for our test duo was very nutritious. Yu Tianlu said with a smile.

Don't look at these black breads that look ordinary, but they are all prepared by Yu Tianlu and asked Shopkeeper Feng to help prepare.

Yu Tianlu made these nutritious breads in the most economical way according to the proportion of ingredients used in those nutritious breads in his previous life. It can fully ensure the energy and protein that the body needs for a day.

So before the exam, these black breads became the staple food of the two friends.

Fortunately, Yan Yue has a great appetite, but he is not too picky about the ingredients, as long as he can eat enough, he will be satisfied.
