Chapter 29

At this time, if Yu Zhen hadn't done this problem in advance and knew the answer, she might have the same idea as the students.

But even so, seeing that Lan Yin wrote the answer to this question accurately at this moment, Yu Zhen also determined that Lan Yin's classmate just wrote a number casually and was lucky to write the right answer.

At this moment, Yu Zhen was a little angry.

LAN Yin first read other textbooks in her class, and then boasted that she could master mathematics.

Although she had written the answer correctly, it was obvious that she had fooled around.

Otherwise, she doesn't even have the steps to solve the problem. How can she know the answer?!

The most irritating thing is that Lan Yin's attitude is to write a number and go back and sit down. She is simply contemptuous of her teacher!

"Lan Yin! That's what you said!"

LAN Yin, who had just returned to her seat, heard the math teacher's words. She looked up at the teacher in surprise, "am I wrong?"

This question really choked Mr. Yu.

But soon, she said positively, "the answer is right, but you don't have the steps to solve this problem. How can you get the answer? It must be blind!"

This reason is beyond LAN Yin's comprehension.

"Such a simple question, you can see the answer at a glance. Why write the problem-solving steps?"

Yu Zhen:?

The whole class:???

What nonsense is Lanyin talking about?!

They haven't learned this problem yet. How can it be simple?!

Some of the students in the class have attended cram classes. Only those who have studied in advance can understand the difficulty of this problem a little.

This is definitely not a simple question!

Just the problem-solving steps, it is estimated that most of the blackboard can be written out.

How come it's so simple that you can see the answer at a glance?

No one believed LAN Yin's words at all.

On the contrary, Yu Zhen will be angry!

"Is this problem simple? OK, then you can do another problem!"

Then Yu Zhen turned around and continued to write a math problem on the blackboard.

The question type of this question is similar to the last big question in this month's exam. If the difficulty of that question is two stars, now this question can definitely have the difficulty of four and a half stars!

LAN Yin sat in her seat. The second after the math teacher finished writing the problem, she opened her mouth and reported a number, "the answer is 5."

With chalk in his hand, Mr. Yu, who had just removed his wrist from the blackboard, paused with his elbow.

She turned around in a daze and looked back at LAN Yin.

If the answer to the first question is that Lan Yin is blind, then LAN Yin can't be so accurate in the second question, can he?

At this moment, Yu Zhen had a guess in her heart, but she couldn't believe it.

"Look at another question!"

In order to verify her idea, Yu Zhen turned around again and continued to write questions on the blackboard.

The students in the classroom who were waiting to see LAN Yin's jokes were clearly telling them that Lan Yin's answer was right again when they saw Mr. Yu's reaction!

But is she really masked?

Who can be so accurate?

A few minutes later, in the second after teacher Yu finished writing the topic, LAN Yin reported a number faintly again, "7."

Now, there was no need to explain. Yu Zhen also understood that Lan Yin really didn't get the answers to these questions!

But how on earth did she get the answer at the moment when her question was finished?

Really, as she said, these questions are too simple?

impossible!

These questions are her to do, and she must solve them in order to get the answer!

Not to mention her, even if she is a famous mathematician in China, she also needs to solve the problem steps, even the most simplified steps!
