……

When you're ready, start your lesson.

Dai Jiaxin projected the courseware on his computer on the large LCD screen and explained the geometry knowledge in primary school mathematics.

"Seek, the area of the circle. First, let's take a look at this diagram......"

Dai Jiaxin explained to Tang Ran, but Tang Ran only glanced at the screen, then lowered his head and looked at the book by himself.

Dai Jiaxin looked at him: "Tang Ran, take class seriously." I, as your teacher, must make sure to teach you. Moreover, I have already given your father, Mr. Tang Zhanting, a lesson plan, and I will benchmark this course and test the results of the exam later, so you have to listen to me carefully, this is the first step. ”

Tang Ran raised his eyelids and glanced at her coldly, "I have already learned the area formula of a circle." Let's move on to the next lesson. ”

Dai Jiaxin asked: "I only talked about the area of the quadrilateral, not the area of the circle, and besides, you have been out of class for three months, I am your teacher, and I need to be responsible for your learning......

Tang Ran said: "I have already learned it myself, and you don't need to repeat the teaching of the area of the circle and the area of the fan. So as not to waste time. ”

Dai Jiaxin paused, "Okay, let's do a few example questions to examine your self-study effect." ”

Dai Jiaxin turned on the computer and searched the question bank, a few questions of elementary geometry,

There are many questions about elementary geometry, and in order to increase the difficulty, she scrolled down the page and brushed out a few questions with a relatively high difficulty coefficient.

"Tang Ran, the teacher has found a few simple questions, you can do them, and let the teacher know about your self-taught knowledge and whether you can complete the easiest questions." After Dai Jiaxin projected the topic on the screen, he hugged his shoulders and looked at Tang Ran.

Tang Ran sat at the desk and took out a piece of paper, "Duoduo, give me a pen." ”

Duoduo immediately took out a pencil from the pen holder and handed it over, "Brother Milk Candy, is this okay?" ”

"Okay."

Tang Ran stretched out his hand to take it.

After handing over the pen, Duoduo lay next to Tang Ran, and his two little hands were supported on the table with their elbows bent.

Duoduo looked at the pencil in Tang Ran's hand, and on the blank paper, he drew a picture with a brush, a round circle, cut into several pieces like a watermelon......

"Brother Milk Candy, are you drawing watermelon?"

Duoduo asked.

"It's not." Tang Ran focused on the pen, finished drawing the picture, wrote a few formulas next to it, and after substituting the numbers given in the title, he directly got the result and put down the pen.

Duoduo looked at the picture he drawn, which she hadn't seen in a picture book, "What kind of melon is this?" ”

Tang Ran pushed the written paper forward, "It's finished." ”

He said to Duoduo again: "It's not a melon, it's a circle, a circle." ”

Looking at Tang Ran's patience with Duoduo, Dai Jiaxin was a little surprised.

Is this still the living ancestor of the Tang family who doesn't like to take care of people, the sick and delicate little young master?

For this sister who is not related by blood, he looks like an elder brother.

Gentleness, patience, more than gentleness, is simply a question to answer, no matter how childish the little one asks, he will give 120,000 points of patience to answer.

Could it be that Tang Ran has changed sex?

It's impossible, when Tang Ran scolded her just now, she was still sharp-toothed, and her lips and teeth could be used as swords, guns, swords, and halberds.

……

Duoduo tilted his neck and glanced at the picture he had drawn, and then at Dai Jiaxin, "Oh...... Brother Milk Candy, this circle you drew is beautiful. ”

She didn't understand the teacher's lecture, but now she understands that the teacher's lesson just now is to teach how to draw a circle.

Brother Milk Candy draws a very round and beautiful one.

Dai Jiaxin picked up the problem that Tang Ran had finished, took a look, and actually used the method of calculus to solve the area of a circle?

She was a little suspicious, "During this time, Mr. Tang has found you other teachers to teach you with me?" ”

Tang Ran looked at the uncomfortable expression on her face, and knew that she was guessing herself with what kind of mind she was thinking about.

Dai Jiaxin didn't believe it, she only taught for a month, even if Tang Ran was a genius, she only learned simple number crunching. No matter how smart a person is, it is impossible for him to be self-taught, it must be Tang Zhanting who has found other teachers for Tang Ran besides her.

This speculation made her feel a sense of crisis in her heart.

"Is the teacher your dad found for you, male or female, to teach you math and other subjects?"

Dai Jiaxin no longer cared about Tang Ran's studies at this time, but became hostile to that potential competitor.

She asked Tang Ran, and she just wanted to know what the strength of the opponents she had never met was.

But Tang Ran neither said yes nor no, only pursed his lips and smiled casually.

"Either you continue to speak, or you leave the class and say something else, which is a waste of my time."

Tang Ran's evasive answer made Dai Jiaxin even more bottomless, frowning, and then looking down at Tang Ran's answer, the thinking was clear, the calculation steps were simple, and the results were accurate.

The questions she came up with were the ones with high difficulty, but the speed at which Tang Ran made them feel that the questions were the easiest ones. She even had some doubts that the quality of the questions in the question bank was not as high as advertised.

Tang Ran didn't even ask her if the answer was correct, but took the time to push the answer to her.

The corners of his mouth turned up, and he confidently wrote that the answer was 100% correct.

She looked at Teacher Dai's painting of Tang Ran, stared straight at her for a while, and then asked her, "Teacher, the circle drawn by Brother Milk Candy is very beautiful, right?" ”

Dai Jiaxin was still suspicious, and under her nose, a soft and cute voice came, and she looked down and saw a white and soft little bun.

Duoduo was looking up at her with a smile on his little pink face, "Teacher Dai." You're teaching drawing, right? ”

After Dai Jiaxin paid attention to Tang Zhanting, she also tried her best to collect relevant information about him.

As the president of Tangji Group, Tang Zhanting has received very few interviews, and he can only find any information about Tang Zhanting on the pages of top economic weekly magazines and mass media.

She also only learned that Tang Zhanting had a nephew.

Tang Feng is a frequent visitor to the current hot search.

This little girl who was introduced by Mrs. Tang as Tang Ran's sister is a cousin or a cousin, and Dai Jiaxin can't be sure for a while.

According to Mrs. Tang's pampering attitude towards Duoduo, it also determines her attitude towards Duoduo.

Dai Jiaxin tried her best to let her gaze be gentle, tried her best to lower her body, and smiled kindly at Duoduo, "Do Duoduo like to draw?" ”

Duoduo said, "I like it." Brother Milk Candy draws this circle, it's so round......"

This little guy winked at her with big eyes, clear eyes, and an innocent look, which was much easier to deceive than Tang Ran.

Dai Jiaxin said to Duoduo: "My brother draws very well. Can Duoduo promise the teacher one thing? ”
