Chapter 642 Classic Arithmetic Problem

Chapter 642 Classic Arithmetic Problem

Similarly, Shen Xia first taught the first aid method for choking, and taught it in a relatively detailed manner. After teaching, he asked someone to come up and demonstrate.

Shen Xia corrected what was wrong, but it had to be said that after what happened with Xiao Yunchen yesterday.

All the students were very serious today and it was obvious that the learning atmosphere was different from yesterday.

Artificial respiration was also taught. Shen Xia taught it in a very serious manner and did not feel embarrassed at all. Life and death are both serious matters.

When Shen Xia spoke seriously, everyone was reluctant to have any evil thoughts. Instead, they felt that when their lives were at stake, how could they have such dirty thoughts? They were unworthy of being scholars.

Of course, everyone is curious about the principle behind this matter.

Shen Xia explained more carefully, trying to make sure everyone could understand.

What don't you understand?

Shen Xia also asked everyone to just ask directly.

They all responded to everyone patiently.

Of course, someone had to come up and demonstrate artificial respiration, but some people were too embarrassed to do it, so Shen Xia just clicked randomly.

Then I tell everyone that you don’t have to really kiss it when demonstrating, just grasp the key points.

Now everyone felt relieved, no one wanted to kiss a grown man.

Time always passes quickly. Shen Xia planned to end the get out of class after she finished teaching. She didn't know if she had exceeded the time limit until she looked around and saw an hourglass in the corner of the classroom.

I just glanced at it casually because I couldn't understand it, so I didn't look at it carefully. In fact, there are marks on it.

The class for Class 2 of the Juren Program has also ended.

Shen Xia doesn’t know!

After listening to Xiao Yunchen's words in the morning, the people in Class 1 who did not listen carefully in class yesterday regretted it to death and wondered if they could listen again.

If they could listen to it again, they would definitely listen carefully.

Of course, there is often only one chance. Shen Xia will not teach any of his classes a second time. If you miss it, you miss it. You can only ask your classmates who have taught you before to teach you.

Shen Xia looked at everyone: "That's all about the two most useful first aid methods at the moment."

After Shen Xia finished speaking, everyone stood up and said, "Thank you, Princess, for your advice."

Shen Xia nodded: "Okay, then I'll go back."

Shen Xia glanced outside.

There were already students there, so it seemed that she had stayed late for class. However, everyone was listening with great interest, so no one reminded her.

Shen Xia left the classroom alone and prepared to leave.

I thought that after teaching the first aid method, I should teach some medical knowledge! Otherwise, I don’t know what to teach next.

So I was thinking about my own things.

As a result, I didn't even see the person coming around the corner.

Of course, that person didn't seem to be looking at the road either, and was staring at the paper in his hand with a frown.

The two collided.

Shen Xia exclaimed: "Hey........"

The two then looked at each other in surprise.

Shen Xia lost his balance and was about to fall to the ground.

The man opposite instinctively stepped back because he bumped into someone, and when he saw Shen Xia was about to fall, he was too late to pull her back.

Shen Xia was ready to fall, but in the end he just felt a pair of hands supporting him on his waist.

Shen Xia immediately stood still and looked at the person behind him.

Ling Heng........

I haven't spoken yet!

Then he said, "What are you thinking about? You didn't even see the person coming from the opposite direction."

As a result, the man opposite said, "Greetings, Princess. It's Su Yan's fault. I was too focused on the questions and didn't notice the Princess."

Shen Xia turned and looked at the student in front of him.

Isn’t this the student who was choked yesterday?

Look at the paper on the ground again.

"It's okay, I didn't notice it, otherwise I wouldn't have bumped into you."

After saying that, she bent down to help him pick up the paper on the ground.

Several pictures.

When Su Yan saw the princess bending down to help him pick up the questions, he was so scared that he quickly said, "Thank you, princess. I can do it myself."

Shen Xiajue realized that he had bumped into someone, so he picked it up for him.

After Shen Xia picked them up, he saw that the questions on the papers were arithmetic. There were only questions but no answers on all four sheets of paper.

The question only said: Everyone pools their money to buy something. If each person contributes 8 cents, there is still 3 cents left. If each person contributes 7 cents, there is still 4 cents left. Please tell me how many people there are and how much the items cost.

There is a square city, its size is unknown, and there are gates in the middle of the city on all four sides. There is a tree twenty steps out of the north gate, fourteen steps out of the south gate, and if you turn west and walk one thousand seven hundred and seventy-five steps, you can see a tree. What is the length of the side of this city?

There is also the problem of chickens and rabbits in the same cage and the problem of two mice digging holes.

After reading it, he handed it to Su Lun and saw that he looked worried.

So he asked, “Is it difficult?”

Su Lun looked at the princess in surprise. Isn’t this difficult?

He was already talented in arithmetic, and this kind of questions were learned by people who were above the level of a juren.

It's just that he likes arithmetic, so the arithmetic teacher often gives him questions, and he takes them very seriously.

In addition, the annual college competition will begin next month, so those who want to participate in the competition have been practicing hard in the past month.

The princess found this question not difficult?

Su Yan looked at the princess and asked cautiously, "Princess, do you think this question is very simple?"

Shen Xia nodded: "It's okay! It's not difficult."

These are just some geometry questions. How difficult are they? They are far inferior to advanced mathematics.

When Su Lun heard Shen Xia say that it was not difficult, his admiration for her reached a new level.

"The princess is truly knowledgeable and talented!" This question would have required even his teacher to think carefully about it, but the princess actually said it was not difficult.

"There are ways and methods to solve problems, for example, this question..." Shen Xia said, taking the question from Su Lun's hand.

Tell him the simple methods one by one.

Because Su Lun was very talented in arithmetic, when Shen Xia told him a simple algorithm, his brain instantly woke up, wondering if it couldn't be that simple.

Shen Xia looked at all four and said, "Got it?"

Su Yan hasn't come back to his senses yet.

Shen Xia thought, she wouldn't teach someone so much that he would become stupid, would she?

Why is this expression so weird?

After a moment, Su Yan came back to his senses: "The princess really is... the reincarnation of Zhou Yin!"

Shen Xia was puzzled: "Who is Zhou Yin?"

Now it was Su Lun's turn to be confused. The princess was so good at arithmetic, but she didn't know Zhou Yin.

At this time, Ling Heng explained beside him: "The most famous scholar of mathematics in contemporary times."

Shen Xia nodded after hearing this: "Oh."

so awkward! ! !

Shen Xia looked at Su Yan: "Do you understand?"

Su Yan nodded quickly: "I understand, what the princess said is true, it's simple and easy to understand."

"By the way, which class are you in?"

Su Yan said: "In the fourth class of scholars."

When Shen Xia heard this, Xiucai Class 4 said, "If you like arithmetic, there is a new student in your class. You can discuss it with Chen Xiaotian more. He knows all these questions."

When Su Lun heard the name, he realized that the student was indeed a new transfer student in their class.

However, he and Song Yu usually don't talk to others.

I didn't expect that they were so knowledgeable.

"Are you only discussing this with Chen Xiaotian? Where's Song Yu?"

Shen Xia listened to others asking Song Yu.

I have to say that Song Yu is really not good at studying.

"Song Yu is a little worse than Xiao Tian."

Actually, Fan Yu can do it, but they are not in the same class.
