Rong Jincheng did not leave, but lowered his head and pointed with his finger: "This, I can do it, why don't you ask me?"

"Ha." Han Yurou sneered, "Can you not cause trouble for me? I'm really sad."

"I really know..." Rong Jincheng's face became more and more innocent. He took the pen from her hand, "I'll do it for you..."

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

Especially when he was doing his best, his eyes were filled with bright brilliance.

The black water pen drew Han Yurou's draft paper, and she sorted out the clues and entry points for this case.

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 asking for praise.

When he solved the problem, she kept looking at the draft paper.

I thought he would draw a turtle or mess up her draft paper, but I didn't expect him to do it.

Moreover, the point she stuck was perfectly connected.

Han Yurou took the pen and said lightly: "Oh."

"Right, are you right? You said I wrote it right?" Rong Jincheng's tone had a bit of coquettishness.

“It should be right.”

"Am I smart?"

Han Yurou didn't say anything.

This question is quite difficult, and she has solved it for several days but has not solved it.

Now that Rong Jincheng is drunk, he can still solve it at a glance, she curled her lips.

"Your idea is correct, but if you forget to screen out the cases from the sample, there will be deviations in the ratio and probability. There is also a comparison of numerical values. If you calculate them accurately one by one, the project volume is too large, you can take an absolute value and then use the correction method. Teach you a cutoff correction I have developed myself. If you are optimistic, do this..."

Rong Jincheng spoke with great spirit.

This kind of question 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 with 9200. Isn't it much easier to calculate this way and save a lot of trouble?" Rong Jincheng wrote and painted, holding her hand tightly.

He told her while writing.

Han Yurou initially repelled his breath, and as she listened, she fell into the gods.

His method is simple and convenient, saving the complex calculation process.

"Okay, look, you can easily solve an arithmetic. Teach you again..."

"I can do it." Han Yurou said lightly.

"Then show it to me."

Han Yurou used her pen to solve the next arithmetic answer, and her eyes were filled with a very serious light.

"Smart, my little fairy is so smart, I can do it once I teach you." Rong Jincheng smiled and kissed her on the cheek, "Kiss it and reward him."

"roll."

"I won't recognize people after using it..."

Han Yurou ignored him. Since she had solved the problem, she would continue to do the remaining questions.

But Rong Jincheng can do questions, which is beyond her expectations.

Rong Jincheng laughed as if he saw her thoughts, "Do you think I'm very 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 she put on her headphones and did the exams alone.
