Play coquettish with Joe

Chapter 1673 A kiss, reward

Rong Jincheng didn't leave, but lowered his head and pointed with his finger: "This, I will, why don't you ask me."

"Heh." Han Yurou sneered, "Can you stop causing trouble for me? I'm really upset."

"I really know how to..." Rong Jincheng's face became more innocent, he took the pen from her hand, "I'll show you..."

Although his breath was a little unstable after drinking, his mind and thoughts were still very clear.

Especially when he is doing something that he is good at, his eyes are full of brilliance.

The black ink pen drew on Han Yurou's draft paper, and gave her the clues and entry points for this case question.

Soon, the white draft paper was densely filled with numbers.

"Look... I will."

After Rong Jincheng finished explaining, he put down his pen and smiled like a child begging for praise.

While he was solving the problem, she kept looking at the scratch paper.

Thought he'd draw a turtle or mess up her scratch paper, but didn't expect him to.

And, it picks up perfectly where she stuck.

Han Yurou took the pen and said calmly, "Oh."

"Aren't you right, do you think I wrote it right?" Rong Jincheng's tone was a little coquettish.

"It should be right."

"Am I smart?"

Han Yurou didn't say anything.

This problem is not small, and she couldn't solve it after several days of solving it.

Now that Rong Jincheng is drunk, she can tell at a glance, she pouted.

"Your idea is correct, but you forgot to select the cases from the sample. Of course, there will be deviations in the proportion and probability. And this numerical comparison, if you calculate them one by one accurately, the project will be too large. You can take an absolute value, and then use the correction method. I will teach you a truncation correction that I have researched by myself. You are optimistic, this way..."

Rong Jincheng spoke in high spirits.

This kind of topic is a small case for him.

Rong Jincheng held her hand holding the pen and kept writing on the draft paper.

Han Yurou frowned.

"For this question, you first multiply the numerator by 5 times, and round the denominator to 9200. Isn't it much easier to calculate this way and save a lot of trouble." Rong Jincheng wrote and drew, holding her hand tightly.

He wrote and talked to her.

At first, Han Yurou felt a little repulsive to him, but she listened and fell in love.

His method is simple and convenient, eliminating the complicated calculation process.

"Okay, look, it's easy to solve an arithmetic. Let me teach you again..."

"I will." Han Yurou said lightly.

"Then show me what you do."

Han Yurou worked out the answer to the next arithmetic with a pen, and her eyes were extremely serious.

"Smart, my little fairy is really smart, she can learn it once she is taught." Rong Jincheng smiled, and kissed her on the cheek, "Kiss, reward."

"roll."

"I don't recognize people after I use them..."

Han Yurou ignored him, since this problem was solved, she continued to do the rest.

It's just that Rong Jincheng can also do the questions, which is beyond her expectation.

Rong Jincheng seemed to see her thoughts, he laughed and said, "Do you think I'm smart? I've been smart since I was a child, and I don't know why."

Han Yurou: "..."

Han Yurou felt that Rong Jincheng was noisy, so he put on his headphones and worked on the questions silently by himself.

Rong Jincheng was still talking non-stop: "When I was in high school, I won five first prizes in the Beijing Mathematics Competition, three first prizes in the National Mathematics Competition, and was No. 1 in the Stanford Business School when I was admitted to college..."
