Daqin: After marrying a vegetative princess, I went crazy with joy

Chapter 154 Arithmetic
Since Ying Zheng encouraged Hu Hai, Liu Bai couldn't say anything more, so he turned to Li Si and asked.

"Li Xiang, how do you remember the rules?"

In the battle against Ying Zheng, he will naturally have to play.

Therefore, the task of refereeing was handed over to Li Si.

"Don't worry, son-in-law, it's just..."

Seeing him in a bit of a dilemma, Liu Bai thought there was something he didn't understand.

"Li Xiang, but it's okay to say!"

"It's just that if you meet the eighteenth son, will you be sent off with a red card?"

Nodding naturally, Liu Bai encouraged.

"When you are on the field, there is no distinction of identity. Li Xiang just plays by the rules!"

Although it was for Li Si, Liu Bai's voice was slightly higher.

When everyone present heard this, they nodded at the same time.

Especially those courtiers agree with this statement very much.

In this way, they can let go of their hands and feet.

Seeing that the two of them had finished chatting, Ying Zheng said slowly.

"Since that's the case, let's start training with the two teams!"

The princes and courtiers all swallowed their saliva.

This...is about to start?

Liu Bai looked at the young masters who were out of breath.

"Are you tired? Father, let's start immediately, do you want to rest for a while?"

The young masters looked at him eagerly, can't you tell from our faces whether we are tired or not?
Do you have to ask?

Of course they want to rest. After running for so long and fighting for so long, they are very tired, okay?
Looking at them contemptuously, Liu Bai said disdainfully.

"What did you say before? Are we going to put them down?"

Looking at Ying Zheng who was standing aside, no one dared to speak.

Seeing this, Liu Bai muttered to himself.

"I don't know if Yuhuatian is busy right now..."

Although it was a soliloquy, the volume was loud enough for everyone to hear.

The young masters were excited all over, and their fighting spirit was immediately high.

"Get them down!"

"Very good, I hope you will do what you say! Now choose 11 people, and the others will be alternates..."

This time Liu Bai didn't need to say much, they had already chosen someone quickly.

Watching their pre-war mobilization, Ying Zheng suddenly found it very interesting, and suddenly became playful.

Turning to face the courtiers, he asked like Liu Bai.

"Do you have the confidence to win?"

Wang Ben and Li Xin looked at each other and took the lead in shouting.

"The ministers will surely return victorious!"

"The ministers will surely return victorious!"

"The ministers will surely return victorious!"

"..."

The shouts shook the sky, quite a bit of the killing spirit on the battlefield.

Nodding in satisfaction, Ying Zheng looked at Liu Bai with a smile.

Seeing him look, Liu Bai asked with a smile.

"Father, can you play?"

"nature!"

He ordered someone to bring back some team uniforms and distributed them to the people Ying Zheng brought.

The generals looked at the blue clothes in their hands carefully, and then imitated the appearance of the young masters, and put on the mandarin jackets on their bodies.

Li Si walked around the crowd, looking curiously at the numbers behind them.

"My son-in-law, I don't know what this means?"

Liu Bai slapped his head, thinking that the numbers in Xiaozhuan were troublesome at the time, so he wrote Arabic numerals, no wonder they didn't know them.

Let everyone stand in a row, pointing at their backs, and explained.

"Please look, Prime Minister, these are the numbers I invented, from left to right they are 1, 2, 3..."

Every time a number was read, Li Si's eyes lit up.

"In this way, just by reading the number, you can know who it represents..."

Liu Bai nodded, that's right!
After staring at it for a long time, Li Si still didn't understand the reason.

"Excuse me, my son-in-law, can these numbers represent any number?"

"nature!"

"Then I don't know how to calculate a hundred and twenty?"

Picking up the branch that beat Hu Hai just now, Liu Bai wrote 120 on the ground.

"How should the [-] million be calculated?"

Gazing at him inexplicably, Liu Bai wrote a 3 on the ground, followed by eight 0s.

Li Si watched silently, feeling that this counting method is simple and easy to use, just draw a circle behind it.

Thinking about it, what is the law of this circle?
"My son-in-law, I don't know how to draw this circle?"

After glancing at the numbers on the ground, and then at Li Si, Liu Bai explained carefully.

"This is not a circle, this is the number zero."

Ah!
Li Si nodded, indicating that he understood, so this is also a number!
"Then what does zero mean?"

He understands one, two, three, etc., but what does zero mean?

"Uh... You can understand that there is no! For example, if this branch is yours, then you have 1. If I take it away now, you will have no more, and it will be zero!"

After listening to his explanation, Li Si suddenly felt that these numbers were much more interesting than the solar system last time.

At least, he understands a lot better than them, doesn't he?

"How to add the zero after that number?"

Just looking at the numbers written by Liu Bai, it is obvious that they are not scribbled, but follow certain rules.

Liu Bai took the branch and began to write on the ground, then pointed to the handwriting and explained.

"One, ten, hundred, thousand, ten thousand...these are all counting units. A single number is a ones digit, a two-digit number is tens, a three-digit number is hundreds, and so on..."

Looking at the handwriting on the ground, Li Si tried hard to think about the meaning of Liu Bai's words.

After a while, he took the branch in his hand and wrote a 1 under the 'a'.

"This is 1, this is ten, this is hundreds...and ten thousand, is it actually billion?"

Every time you say a sentence, draw a zero under the following unit.

Liu Bai looked at him appreciatively.

"Yes, that's it!"

Nodding his head, Li Si asked suddenly, looking at the handwriting on the ground.

"Then what is the unit behind this gigabyte?"

???

What the hell are you talking about?
If labor and management knew about it, wouldn't they have written it out a long time ago?
Glaring at him, Liu Bai said angrily.

"What do you ask so many questions, you can't use them!"

Seeing that he fell ill again for some reason, Li Si quickly changed the subject.

"I have one. After you take it away, I will become zero. But if I have one and you insist on two, I can only find someone else to lend you another one. How do you plan this?"

Liu Bai's eyes widened when he heard the words, talent, you can think of so much?

In an instant, the irritability in my heart disappeared.

For some reason, I felt that Li Si was a malleable talent.

Taking the branch in his hand, Liu Bai drew a horizontal line on the ground.

A 0 is written in the middle, and a dozen positive numbers are written starting from 1 on the right.

Starting from -1 on the left, a dozen negative numbers are written.

"Look, Li Xiang, this line is infinitely long, understand?"

not understand!
But Li Si still nodded, listen first, and then talk after listening!

"The center is 0, and the right side is the normal number used in daily life, which is called a positive number, and the number on the left is preceded by a minus sign, which is called a negative number."

"You have three, I took one from you, and you have two left, then these two are a positive number 2; you have three, I took you five, and you borrowed two from other places, that is -2 .”

"Theoretically speaking, positive numbers are infinite like negative numbers, understand?"

Li Si, who didn't understand very well at first, really understood after his explanation.

Isn't this a simplified version of the Suanjing?It is indeed much easier to understand.

Interesting, the son-in-law can always come up with many interesting things.
