"Wang Li." Li Chen gritted his teeth.

This bastard Wang Li is simply a rat shit in a pot of white rice, just as conspicuous as TM.

"Wang Li, the teacher called you." Meng Fei sat next to Wang Li, poked Wang Li with his finger, and said.

"who I am?"

"Where am I?"

"What am I doing?" Wang Li was awakened from his beautiful dream, and his mind was a little confused for a moment.

"Wang Li, repeat the question I just said." Li Chen glared at Wang Li.

In Li Chen's opinion, it is definitely impossible to let this kid do the questions. He can repeat the questions and find a way to go.

"I can't. I was sleeping just now and didn't hear it." Wang Li said with confidence.

"What?"

"Is that tough?"

"Niu Pi." Everyone looked at Wang Li, the classmate who was coaxing by Niu Pi.

"sleep?"

"Are you so confident when you sleep?"

"Who told you to sleep, did I give it?"

"Do you think the school is your home, and you can sleep whenever you want?" Li Chen looked at the muddy man and roared.

"That wasn't what you said when you asked me to hang the blackboard just now."

"I ask you, why do you have to do this kind of work for students?"

"You said, treat the school as your own."

"I asked you again, what will you do after hanging the blackboard."

"You said, do whatever you do at home now."

"I'm just sleeping at home this time."

"You really let me sleep." Wang Li said with a grievance. He wondered why this man, who is still a marquis, didn't keep his word?

"Ha, ha, ha." The students couldn't help but laughed.

"Meng Fei, your friend is really..." Ying Yue pointed at Wang Li and said.

"Sister Yue, no matter how you speak, don't curse people." Meng Fei looked at Wang Li with disgust.

"Hu, Hu, Hu."

"Wang Li, go out." Li Chen said angrily.

"You go out, go out, what's so great about it?" Wang Li muttered and walked out of the door.

"Oh, I said Lao Wang, look outside the door, is your little king?" In the office opposite the classroom, Wei Liaozi asked Wang Jian.

"If you don't say it, you, I will be civilized, you, me, and he." Wang Jian said angrily.

"Why did your grandson come out?" Wei Liaozi quipped.

"It's cool outside." Wang Jian said depressedly. His grandson was really a grandson, and he was just embarrassed.

"Oh, Lao Wang, why are you going out?" The two were chatting enthusiastically, and Wang Jian suddenly walked out the door.

Of course, the hot talk was also what Wei Liaozi thought so, and Wang Jian actually didn't want to pay attention to him. This guy's kung fu skills are no less than the art of war.

"Don't let it go." Wang Jian replied angrily.

"You kid, I'll be standing outside next time and I'll break your legs when I get home." Wang Jian pretended to go to the thatched cottage and whispered when he passed by Wang Li.

"If you break my leg, then they push me out, and I'll sit outside and listen." Wang Li said with a clear thought.

"Let's continue." Li Chen said. After driving Wang Li out, the atmosphere in the classroom became much fresher in an instant.

"Only three people have come up with this question, Li Qing, Ying Yue and Meng Song." Li Chen praised.

It was not surprising that Li Qing and Ying Yue could do it. After all, these two families are well-educated and have both been involved in the subject of arithmetic. Meng Song is just a child of a merchant, and it is indeed beyond expectations that he can quickly calculate it.

"Although you all calculated it, it has been too long since it was available," Li Chen said.

"Teacher, this is no longer a slow end. My accountant is just at this speed." Meng Song said.

"Yes, the teacher is really not slow." Li Qing also echoed.

"I'm not saying you're slow, I'm saying your method is too slow. You may be the fastest to use the existing calculation method, but what if you change the method?" Li Chen continued.

Everyone fell into silence, obviously they didn't know how to do it.

"Let me do this, I'll do this question, you guys watch it." Li Chen pondered for a few seconds and said. After all, is there any harm only if there is comparison?

"Who will change these numbers?" Li Chen said to the students.

"Teacher, I'll do it." Ying Yue suddenly said.

"You can't." Li Chen refused.

"Teacher..." Ying Yue was puzzled.

"I'm afraid others will say you're a entrusting person." Li Chen said.

"Can you stop calling the teacher? It makes people scratch their hearts?" A bitch thought in his heart.

"Teacher, I'll do it." Li Qing said.

Assuming that every wealthy businessman in Daqin needs to pay 869 taels of silver, then how much tax does 487 merchants in Daqin need to pay? The question after Li Qing changed it to this.

"How much time does the teacher need to calculate the answer?" Li Chen asked.

"Half incense stick? I think." Li Qing said.

"The skill of a cup of tea is the fastest." Someone guessed.

"423,203." Just as everyone was speculating, Li Chen reached out to write the answer on the blackboard.

"This is impossible?"

“Too fast?”

"The answer is wrong, right?" the students questioned. This was incredible. How could someone calculate such complex arithmetics so quickly?

But after some calculations, everyone soon found that the number was exactly the same.

"Teacher, you are a genius, right?" asked a student, and the other students immediately agreed.

"I'm not a genius, I'm just an ordinary person."

"Mathematics is different from other disciplines, and the answer to mathematics is unique and fixed."

"One plus one can always be equal to two, and there will be no other answers."

"So, mathematics has traces to follow. As long as everyone masters the skills, everyone can quickly calculate the answer."

"Remember, brothers may betray you, and the wife may deceive you, but if you don't know how to do math, you won't know." Li Chen looked at the students and said seriously.

"Teacher, can each of us calculate the answer as quickly as you do?" asked a student.

"Of course, it may be faster than the teacher." Li Chen said.

Arithmetics are just the most basic things in mathematics. Whether it is life, business, science, or chemistry, it requires mathematics.

Business activities require accounting and accounting, scientific research requires parameters, and map drawing requires data.

Mathematics will be the fast-moving carriage and horse of the Qin Dynasty, and only this carriage can bring Da Qin away from the farming era and into the industrial era.
