As you can see from the previous one, it is a mathematical multiplication calculation of several three-digit numbers to five or six digits, which are not calculated by formulas. The fastest update visit wèn:.

The next question is calculated by an arithmetic, and the font is not the same as the one above......

Thinking of what Rong Zhan said just now, Tan Jincheng couldn't help frowning.

It seems that Rong Zhan gave Yun Rui a few questions, that is, the fonts at the front are obviously mature. The answer with immature strokes in the back is obviously written by Yun Rui.

The column calculation is also Rong Zhan's font, and Yun Rui does not calculate vertically at all, but directly writes the answer after the equal sign.

Tan Jincheng narrowed his eyes, obviously discovering something suspicious in it.

Could it be that Yun Rui's mental arithmetic ability is very strong?

At this moment, Yun Rui handed Tan Jincheng another piece of paper.

After glancing at it, Tan Jincheng couldn't help but twitch the corners of his mouth. This is a differential problem that falls within the range of higher numbers.

But the problem is that Yun Rui has never gone to school, and it is impossible for him to know what is the concept of differentiation and what is integral.

No, even if I went to school, the concept of calculus was only a little dabbled in the third year of high school, and I really learned calculus in college.

Ordinary high school students won't, let alone Yun Rui, who hasn't gone to school yet?

If it was taught to her by Yun Jingxiao, it would be even more ridiculous, Yun Jingxiao was a standard scumbag back then, and she couldn't learn math well in junior high school, let alone these things.

Tan Jincheng looked at Yun Rui, his gaze was on Yun Rui's crystal clear eyes. Yun Rui's eyes didn't seem to convey anything, but Tan Jincheng just knew that he was looking forward to it......

But what to expect?

Looking down at the question of the high range written on the paper, the child's brushstrokes are very immature, but they are very serious, especially the mathematical symbols, which are written very standard and standardized, not like ordinary children, written crookedly.

Tan Jincheng's heart moved slightly, what does this kid mean, let him solve this problem?

After thinking about it for a while, Tan Jincheng still picked up the pen and wrote on the paper, and smooth mathematical symbols and numbers appeared from under the tip of his pen.

Soon, he solved the problem and handed the paper directly to Yun Rui.

Yun Rui took the paper, looked at it, and his eyes lit up!

Immediately afterwards, he actually began to write on the paper again, and it turned out to be another advanced math problem, and this one was more than one level more difficult than the one just now.

Tan Jincheng squinted his eyes, he has always been very sensitive to mathematics, plus finance, which is closely related to mathematics, and mathematics can exercise people's logical thinking ability, he has never given up mathematics.

Therefore, this question is a bit difficult, but it can't be difficult to talk about Jin Cheng.

It's just that this question is more troublesome to solve, Tan Jin Cheng wrote a full page, and took a piece of paper to write half a page before he finished solving this question.

He sat on the chair next to the bed, he wrote, Yun Rui read, he finished writing, Yun Rui also finished reading.

Tan Jincheng put down the pen and looked at Yun Rui, who was leaning beside him to watch him solve the problem, and he didn't know why, his heart suddenly softened.

And Yun Rui was also looking at him.

Tan Jincheng clearly saw the bright 'color' from Yun Rui's eyes. The eyes are as black as ink, bright as stars.

This is his child.

Tan Jincheng has never had a moment to realize more clearly than now that this child is really his, his bloodline!

The decision that had been made would not be shaken, but his heart was trembling.

Although Tan Jincheng didn't say that he was in a bad mood, and he didn't show that he was in a bad mood at all, Yun Rui seemed to be able to sense that he was in a bad mood.

He hesitated for a long time before he slowly stretched out his soft little hand and covered the back of Tan Jincheng's hand.

Tan Jincheng froze instantly.

The feeling of that little hand covering his hand was amazing.

It was a feeling that could not be described in words, and at this moment, he really felt that words were too scarce to describe this feeling at all.

That little hand is very soft, very small, and very thin, not like the average child's 'meat', the fingers of this little hand are very slender, and it makes people feel distressed when they look at it.

Tan Jincheng's gaze stayed on this little hand, and he didn't dare to look at Yun Rui's eyes. I don't know why, he was afraid to look into Yun Rui's eyes at this time, because he was afraid that he would waver, and he was afraid that he would change his previous decision.

That little hand was originally just very carefully attached to the back of Tan Jincheng's hand, but I don't know when it started, this little hand began to slowly exert force, trying to hold Tan Jincheng's index finger.

By the time Tan Jincheng found out, he had already held his index finger!

Tan Jincheng turned his head slowly, his gaze moved up, and he met Yun Rui's eyes. In the dark eyes, there were a few stars flashing at this time, so brilliant that people could hardly take their eyes off it.

What made Tan Jincheng even more unbelievable was that Yun Rui actually smiled at him.

Although the curvature of Yun Rui's 'lips' was very shallow, he could still feel that he was laughing, he was really laughing.

There was a sudden pang in his heart, and in the next second, Tan Jincheng Huo Ran got up, and without even talking to Yun Rui, he walked out of the ward quickly!

He wanted to breathe, he really wanted to breathe, he felt like he was so depressed that he was about to run out of breath.

It's really, it's hard to be extreme.

Because Tan Jincheng's movements were too big, Yun Rui, who was originally pulling Tan Jincheng's finger, seemed to be thrown away.

Yun Rui sat on the 'bed' in a daze, his eyes looked at Tan Jincheng's back very coldly, and he seemed to have escaped out of the ward and closed the 'door' of the ward.

And on his hands, there is still a residual temperature and touch that belongs to Tan Jincheng.

A trace of loneliness flashed in Yun Rui's dark eyes, and he looked down at his little hand......

Is this how Dad feels?

Mom told him about his dad every day. But Dad looked strange, he could feel that Dad liked him, but ...... But why did Dad seem to be so scared? Afraid to like him?

Yun Rui's eyes flashed with a 'confused' color.

He has known since he was a child that he has a high IQ, especially for numbers and language, and his memory is also very good, so it can be said that he can never forget.

Adults think he's a child, but he's not. He understands everything. But he also had to admit that what he didn't think he understood was the so-called feelings......

He doesn't understand the kind of thing that doesn't rationalize 'sex' at all, and only relies on emotional 'sex', even if he works hard, he can't understand it.

Yun Rui lowered his head and gently squeezed his hand: Dad should really be right, but what about Mom?
