Chapter 175: Choosing Between Cheating and Doing the Test

Teacher Su Hao is experiencing the second Waterloo in his teaching career.

The last Waterloo was when Uncle Fan brought up calculus when he was teaching junior high school mathematics.

The reason was that after the uncles and aunts of the elementary mathematics class entered the class, Su Hao planned to let them do a set of questions first to get a feel for their foundation so as to determine the teaching direction and teaching plan.

The questions were from a test paper for junior high school entrance examination, with the majority being multiple-choice questions and the number of questions not being large.

While the uncles and aunts were doing their homework, Su Hao stood with his hands behind his back and looked around. He sighed as he turned around: "The level of the uncles and aunts this year is really good, but it should be rare to find an expert like Uncle Fan."

Newly married Uncle Fan still firmly chose math classes this year. I heard that he also signed up for square dancing with Aunt Wen, but Uncle Fan is in the beginner class and Aunt Wen is in the intermediate class, so they cannot be dance partners.

After Uncle Fan arrived, Su Hao's one-on-one doctoral training was extended for another year free of charge.

In addition, Uncle Fan strongly requested the school to open an advanced class for him, and even wrote a letter of advice to Lin Qinglan for this purpose.

After Su Hao heard this, he tried his best to stop Principal Lin, fearing that she would agree.

If an advanced class really is opened, Uncle Fan will be the only student who can attend it, and then he may not be the one teaching Uncle Fan.

Su Hao was really afraid that when he couldn't speak anymore, Uncle Fan would snatch the chalk away and force him to roll down and listen to him.

After all, it was difficult enough for him, a master's graduate, to teach Uncle Fan, who was supervising doctoral students. What's more, Uncle Fan was his supervisor's teacher. If his master's supervisor taught him wrongly, he would come from the school to educate him.

He was thinking about Uncle Fan, but his eyes noticed another person.

This uncle had very long hair and a beard, and was so thin that he looked like a bag of bones. However, he wore loose clothes, and his coat hung loosely on his body.

What caught people's attention was not his clothes but his strange behavior.

At this moment, everyone in the classroom was quietly doing their homework, but he was the only one who was muttering to himself in front of the test paper. He quickly shook three copper coins in his hand and threw them upwards. The coins turned in the air and fell back on the table, scattering everywhere.

He glanced at the coin and quickly chose an answer.

"Is this... fortune-telling?"

Su Hao remembered that when he introduced himself, he said his last name was Duanmu, a very special last name that made him remember it immediately. He didn't expect that his method of answering questions was also so unique.

Uncle Duanmu had to choose between cheating and doing the exercises.

Su Hao took a closer look. The three copper coins had two sides facing upwards and one side facing downwards. Uncle Duanmu looked at the copper coins and chose option B.

“Why B?”

"Three copper coins, one yang and two yin are B."

After the question and answer, both of them were stunned.

Su Hao was shocked that the answer chosen by Uncle Duanmu was correct.

If he answered a question correctly, Su Hao could still comfort himself that it was just a coincidence.

"Teacher? This isn't cheating. It's just a trick at best." Uncle Duanmu was stunned and said guiltily while covering the paper.

"It's okay, don't worry about me, just continue writing." Su Hao stared at him without blinking.

Uncle Duanmu continued to practice and wrote down a question.

Su Hao also saw the whole process of his practice.

He hardly read the question, and after a few seconds he decisively threw the coin in his hand. After the coin drew a neat arc, the answer was revealed - two reverse sides and one front side.

"Choose C for this question!" Su Hao answered immediately, and then asked Uncle Duanmu for confirmation, "Is that right? I think it must be right!"

He did not look at the question, but judged solely based on the coin thrown by Uncle Duanmu.

"No, two yang and one yin, the answer to this question is D." Uncle Duanmu put away the copper coin and wrote down the answer decisively.

Su Hao looked at the question carefully and was surprised to find that Uncle Duanmu's choice for this question was also correct!

He quickly glanced at the questions above and found that they were all correct.

It is really possible to answer questions correctly just by relying on concepts and luck. Su Hao, who studies mathematics, pays attention to using numbers and theorems for proof, so he doesn't believe it.

But the fact is that the answer that Uncle Duanmu "calculated" using magic is correct.

Su Hao's curiosity was aroused, and he asked anxiously, "Why? What is the principle behind this? What do yin and yang represent?"

In shock, he spoke a little loudly, attracting the attention of the whole class.

Su Hao hurriedly covered his mouth and lowered his voice: "Uncle, don't leave after class, I'll come find you."

This technique is amazing, he wants to learn it!

When he learns it, he will use it to scare Uncle Fan to death, but it seems to only apply to multiple-choice questions.

After this incident, Su Hao couldn't help but go to see Uncle Duanmu, and found out that he could do more than just toss coins, he could also count with his fingers.

As soon as the test papers were collected, he couldn't wait to take out Uncle Duanmu's paper.

I took a quick look and found the accuracy rate is very high.

Between establishing his authority as a teacher and dealing with Uncle Duanmu, Su Hao chose to ask questions without hesitation.

"Uncle, can you tell me what the principle is?"

Uncle Duanmu scratched his head and asked doubtfully, "Do you really want to learn?"

Su Hao nodded vigorously, feeling a little embarrassed: "Can this be passed on to others? If not, forget it."

"There is no secret to this, and the principle is very simple." Uncle Duanmu took out his copper coin again and explained it in detail.

Only then did Su Hao realize that these copper coins did not look simple. Just looking at their quality, it was clear that they were quite old.

"Take three copper coins, the reverse side is Yang and the front side is Yin."

"Throwing three Yangs upwards is A, two Yangs and one Yin is D, one Yang and two Yins is B, and three Yins is C."

Su Hao nodded ignorantly and was about to ask further questions.

Uncle Duanmu suddenly put away the copper coin and said earnestly: "The principle is very simple, but I suggest that you don't use it casually after learning it."

"why?"

Faced with his questioning, Uncle Duanmu smiled but did not answer.

……

On the other hand, on the first day of school, Lin Qinglan invited a servant to come to school.

I guess the boy himself didn't expect that his elder would get into trouble just half a day after going to school.
