A widower's entertainment

Chapter 36 [Mathematical Problems]

This is indeed a problem.

Once the identity of the deceased is identified, the police will definitely come to find Chen Jing. Can mother and daughter withstand the police's persistent interrogations? If you only prepare a set of flimsy denials, as soon as the police catch a conflict, there will be flaws immediately, and you will definitely be unable to help but drag out the truth.

You must have perfect logic and the best defenses in place, and you must build them now.

Don't worry, he told himself. Anxiety cannot solve the problem. There must be a solution to this equation.

Shi Hong closed his eyes. He always did this when faced with a difficult math problem. Once the information from the outside world is blocked, the mathematical formula will begin to continuously transform in his mind, but what appears in his mind now is not a mathematical equation.

……

"Dad, how do you solve this problem?"

Lin Zhaoxi came to ask Lin Youcheng with her math homework. She would not ask Lin Youcheng before, but it is different now. She will ask Lin Youcheng, and her father knows the answer.

This made Lin Zhaoxi feel more and more powerful about his father.

Although he did not graduate from high school, Lin Youcheng actually graduated from college. Although he studied liberal arts instead of science, Lin Youcheng could still answer math problems for the fourth grade of elementary school.

When Lin Youcheng saw Lin Zhaoxi coming to ask him a question, he naturally put down his pen and answered the question for Lin Zhaoxi immediately.

There is no way around it. Taking care of Little Carrot Head not only takes care of food and clothing, but also helps with homework.

At this point, Lin Youcheng thought that he was better than the child's mother. After all, the child's cultural level was not high, so he naturally had no way to answer the little carrot head's questions.

Looking at the very dated cover illustration of the mathematics book in front of him, which was very lifelike, Lin Youcheng couldn't help but sigh that he didn't know when the poisonous textbook appeared. This thought just flashed through Lin Youcheng's mind. Start reading the math questions asked by Lin Zhaoxi.

Lin Youcheng originally thought that what Lin Zhaoxi wanted to ask was a math question, but he didn't expect that Lin Zhaoxi actually asked about abacus?
  Well, in the 80s, there were abacus courses in primary school mathematics textbooks.

Naturally, some children go to school carrying abacus on their backs.

"..."

Forgive Lin Youcheng, a college student in the 21st century, for not knowing the calculation rules of abacus at all.

It was a bit embarrassing. I didn’t expect that there were elementary school math problems that even college graduate Lin Youcheng didn’t know.

But fortunately, there is still the memory of the original body.

Of course, the original person has naturally learned some abacus, and there are some formulas about abacus in his memory, one up and one, two up and two, three down and five go to two, four down and five goes to one, five goes to five and goes to one, six goes up and one goes Five goes into one, seven goes up and two goes out, five goes into one, eight goes up and three goes out, five goes into one, nine goes up and one goes into one...

Lin Youcheng frowned, trying to explain clearly, and said: "The teacher should have said that the beads above the beam are called upper beads, and the beads below the beam are called lower beads. One lower bead means 1, and the five lower beads represent 1. A strain means 5, and a bead means 5, right?"

Lin Zhaoxi nodded in understanding.

"Xi'er, you can understand it this way. One hand is the upper bead, and one finger is the lower bead. There are five fingers on one hand, so it means that one upper bead has five lower beads."

"I understand."

Lin Zhaoxi smiled and nodded.

"Xi'er, if you look at the positioning point, which is where the ones digit is, then this means 5, and this means 15."

Lin Zhaoxi's grades were not bad, so he understood quickly and asked again: "Dad, can you buy an abacus for me?"

"Of course."   Lin Youcheng naturally would not let his daughter talk on paper and do mental calculations by looking at diagrams. After all, it is really sad to do that.

In the past, the original person was reluctant to part with that money, but now he naturally won't save it. After all, as the old saying goes, no matter how hard it is, you can't give up on your children, and no matter how poor you are, you can't give up on education.

The key is that Lin Youcheng is not short of money now, so he thinks he can also buy an abacus for Lin Zhaoqing.

As for Lin Zhaomei, who is in preschool, forget it. In the future, these smaller carrot heads can use the abacus used by her older sisters and brothers. This can be regarded as thrifty and good housekeeping.

"Great!"

Lin Zhaoxi was very happy when she heard that Lin Youcheng agreed to buy her an abacus. She had wanted an abacus of her own for a long time.

"Thank you dad!"

Lin Zhaoxi took his book and ran away happily.

Seeing Lin Zhaoxi leaving happily, Lin Youcheng breathed a sigh of relief. At this moment, he was still grateful that the original person still had abacus in his memory and was not really ignorant.

Otherwise, he really didn't know how to explain to Lin Zhaoxi the meaning of clearing three sets, clearing nine sets, and playing a hundred pieces.

Of course, luckily Lin Zhaoxi didn't continue to ask.

Lin Youcheng has no special feelings about the disappearance of abacus from primary school textbooks. He just feels that he will never see children carrying abacus to school again.

Lin Youcheng withdrew his gaze and looked at the novel "The Devotion of Suspect Answers to the world's most unsolved mathematical puzzles.

It should be said that Lin Youcheng only knew the answers and ideas, but he did not know the complete problem-solving process.

After all, he studied liberal arts. If it weren't for his interest in the news, he might not have gone out of his way to understand that particular world mathematics problem.

In the story "The Devotion of Suspect suicide.

Lin Youcheng was just thinking that for a mathematician like Shi Hong, who has rigorous logical thinking and outstanding talent, if he solved a world mathematical problem in this story, would it become an unknown foreshadowing in the story.

In the original story, the mathematical genius Shi Hong wanted to prove the four-color principle that had already been proven.

So, what if we switch to another mathematical problem that has never been proven?
  And in this story, there is actually no need for a complete problem-solving process, only answers and solutions.

Perhaps, a simple brushstroke, without making any move, is the best foreshadowing.

Will it be possible that in a long time in the future, that mathematical problem will be solved, and then it will be discovered that the correct answer to that mathematical problem has already been given by Shi Hong in the novel?

Or is it--

In the near future, by chance, a reader discovered that the answer to the world's mathematical puzzle given by Shi Hong was correct?

Of course, maybe——

This is a simple, correct answer that no one will notice after a long, long time.

　I really need a lot of support!
