What Liu Cheng said was not wrong at all. After Liu Shui completed the addition and subtraction within ten of the two large pieces of paper he presented, he no longer needed to count with his fingers when accepting Liu Cheng's test.
, basically there is no unnecessary hesitation, and the answer can be given directly.
It is normal for such an effect to occur.
Anyone who can do so many simple additions and subtractions in a short period of time can calculate quickly.
It was already very late at this time, and Liu Cheng was preparing to go to bed and rest.
But Liu Shui, who was experiencing how little he could read when he used it, didn't want to rest. He just wanted to learn more arithmetic knowledge.
Seeing this, Liu Cheng once again wrote him two pieces of paper with addition and subtraction questions, this time within one hundred.
Liu Shui was confused when he took it.
When he was not proficient in addition and subtraction within ten, he could count on his fingers to calculate, but now this is no longer possible.
He simply doesn't have that many fingers and toes to do this.
At the critical moment, Liu Cheng, the elder brother, stood up and used the vertical calculation method of addition and subtraction.
Liu Cheng wrote out the vertical formula, first explained the rules to Liu Shui, and then began to calculate it step by step.
After Liu Cheng did a few vertical poses, he started to let Liu Shui do it by himself.
The vertical calculation method is a very good calculation method that can simplify complex numerical calculations and turn them into single-digit addition and subtraction.
After being tortured by Liu Cheng's previous two papers, Liu Shui became very proficient in the addition and subtraction of various digits. Under such circumstances, after spending some time and figuring out how to use them, he soon
I quickly discovered the benefits of this kind of thing.
"Brother! That's great! This is really good stuff!"
After Liu Shui experienced the usefulness of the vertical calculation method in his predecessor, he couldn't help but praise it. He was extremely happy and excited.
Of course this is good stuff!
This thing can appear in the textbooks of the nine-year compulsory education system nearly two thousand years later. It is definitely a very useful and practical thing. Otherwise, it would not be qualified to be put there for students across the country to learn.
…
It was late at night, Liu Cheng had fallen asleep, and the oil lamp was still lit in the room where Liu Shui was.
Liu Shui was lying on the desk, holding a pen in his hand, writing and drawing, and calculating the questions seriously...
Ushisuke didn't sleep either.
It's not that he doesn't want to go to sleep because of how hard he works, but because he can't go to sleep.
At this time, he was in Dong Zhuo's room, telling Dong Zhuo what happened today.
"The affairs of the clan are the royal family's own business. This time the young emperor directly issued the decree, and Zong Zhengqing Liu Song personally took action... I think this is also a good thing. After all, Brother Kede is my father-in-law, and you promoted it with your own hands.
Yes, he looks glorious, and it’s good for you, father-in-law..."
Ushifu said carefully.
One thing brings down another thing.
Niu Fu, who had always been lawless, was really honest when in front of Dong Zhuo, his father-in-law.
He seemed careful in everything he said.
Dong Zhuo nodded and said nothing, but turned his attention to his other son-in-law Li Ru, who had not spoken much.
After receiving Dong Zhuo's gaze, Li Ru paused for a moment before speaking: "Father-in-law, I don't think things are that simple.
After Liu Cheng became King Jing of Zhongshan, he would usually just talk to himself and let us listen to him for a while, but now the little emperor suddenly did such a thing, I am afraid he has the intention to win over this person.
Liu Chengxin came to Luoyang without any foundation, but he has extremely high martial arts. The purpose of the little emperor doing these things at this time is self-evident."
Li Ru said this, paused, and then continued: "The little emperor is too young and obviously cannot think about so many things. There must be someone else who plans these things for him."
Dong Zhuo nodded: "This makes sense. We are just generals after all, and we are not as qualified as these guys when it comes to our qualifications to be officials.
We deposed the emperor and established a new emperor. They were all trampled under our feet and let us take the lead. Naturally, they felt unbalanced and uncomfortable in their hearts.
It is normal to do some small actions now.
These people are all intertwined. We have only taken power not long ago, and people's hearts are unstable. We need to use them to calm people's hearts and stabilize order. Otherwise, we will pick up a knife and chop them off one by one.
No one of these people will suffer any loss if they are killed!"
After speaking, Dong Zhuo's tone couldn't help but become more serious, bringing out some murderous intent.
Seeing this, Niu Fu beside him couldn't help but turn his head and give Li Ru a sneaky look.
Because Dong Zhuo said these words, he agreed with Li Ru's words instead of his own.
Li Ru did not answer Dong Zhuo's words and pretended not to have seen Niu Fu's action.
Instead, he waited for a while and asked: "How will you face Liu Cheng in the future? What attitude should you have?"
"Let's wait and see for a while. The rest can be better than before, but when it comes to military strength, don't touch it for now."
Dong Zhuo thought for a while and then said this.
He was a military commander and knew the power of soldiers and horses, so he took it a bit seriously.
"But, father-in-law, this has nothing to do with brother Kede! It's the little emperor and those damn people who are doing it. Brother Kede..."
Niu Fu spoke up to help Liu Cheng distinguish the situation and complain.
Dong Zhuo glared at Niu Fu, but after saying in his heart several times, 'This is his son-in-law, he was chosen by himself at the beginning', he explained to him: "This is a conspiracy used by those guys. After they
After doing such a thing, after Liu Cheng was solemnly recognized as a clan member of the Han Dynasty, no matter what, I would be wary of him in my heart, after all, he is different now from before..."
