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

"Ha." Han Yurou sneered, "Can you stop causing trouble for me? I'm really in a bad mood."

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

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

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

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

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

"Look...I can do it."

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

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

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

Moreover, the point where she was stuck was perfectly connected.

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

"Is it right? Do you think what I wrote is right?" Rong Jincheng's tone contained a hint of coquettishness.

"It should be right."

"Am I smart?"

Han Yurou said nothing.

This question was so difficult that she couldn't solve it for several days.

Now that Rong Jincheng was drunk and could figure it out at a glance, she curled her lips.

"Your idea is right, but you forgot to screen out the cases from the sample. Of course, the proportions and probabilities will be biased. There is also this numerical comparison. If you calculate them one by one accurately, the amount of work will be too large. You

You can take an absolute value and then use the correction method. I will teach you a truncation correction that I developed myself. If you like it, do this..."

Rong Jincheng spoke with great enthusiasm.

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 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 told her at the same time.

Han Yurou was a little repelled by his aura at first, but as she listened, she fell in love with him.

His method is simple and convenient, eliminating complicated calculation processes.

"Okay, look, I can easily solve arithmetic. I'll teach you one more time..."

"I know how." Han Yurou said calmly.

"Then you do it for me."

Han Yurou used her pen to figure out the answer to the next arithmetic question, with an extraordinarily serious light in her eyes.

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

"roll."

"You don't recognize people after using them..."

Han Yurou ignored him. Now that the problem was solved, she continued to do the remaining problems.

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

Rong Jincheng seemed to have read her thoughts and laughed: "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 she put on her headphones and worked on the questions silently by herself.
