At this time, if Yu Zhen had not done this question in advance while preparing lessons and knew the answer, she might have thought the same as the students.

But even so, seeing Lan Yin accurately write the answer to this question, Yu Zhen also determined that Lan Yin just wrote a random number and just got lucky, so she wrote 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 do math.

Although she wrote the answer correctly, the answer was obviously just a random mistake.

Otherwise, if she didn’t even have any steps to solve the problem, how could she know the answer?!

The most annoying thing is that Lan Yin's attitude was that she wrote a random number and went back to sit down, which was simply despising herself as her teacher!

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

Lan Yin, who had just returned to her seat, heard the math teacher's words, looked up at the teacher with a surprised expression, "Did I do something wrong?"

This question really made Teacher Yu choke.

But soon, she said seriously, "The answer is right, but you don't have any steps to solve this question. How can you get the answer? You must be confused!"

This reason was beyond Lan Yin's understanding.

"A such a simple question can be seen at a glance, why do you still need to write the answers to the problem-solving steps?"

Yu Zhen:…?

All students:???

What nonsense is Lan Yin talking about?!

They haven't learned this question yet, why is it simple?!

Only some students in the class attended cram school, and only those who previewed in advance could understand the difficulty of this question.

This is definitely not a simple question!

Just the problem-solving steps can probably be written all over the blackboard.

Why did it come to Lan Yin's mouth? 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 was about to be furious!

"This question is simple? OK, then you can do another question!"

As he said that, Yu Zhen turned around and continued to write a math problem on the blackboard.

The type of this question is similar to the last major question this month. If the difficulty of the question just now is two stars, the difficulty of this question is definitely four and a half stars now!

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

Teacher Yu, who was still holding chalk in his hand, had just moved his wrist away from the blackboard, paused on his elbows.

She turned around in a daze and turned to look at Lan Yin.

If the answer to the first question just now was Lan Yin's blind guess, then Lan Yin can't be able to accurately guess the second question, right?

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

"Look at another question!"

In order to verify his thoughts, Yu Zhen turned around again and continued to draw questions on the blackboard.

The students in the classroom who were originally waiting to watch Lan Yin’s jokes saw Teacher Yu’s reaction, clearly told them that Lan Yin’s answer was correct again this time!

But was she really confused?

Who can be so accurate?

A few minutes later, the second after Teacher Yu finished writing the question, Lan Yin once again reported a number in a faint tone, "7."

Now, there is no need to explain anymore, Yu Zhen also understood one thing. Lan Yin is really not confused about the answers to these questions!

But how did she get the answer the moment she finished her question?

Are these questions really too simple, just like she said?

impossible!

She did these questions and had to solve them in order to get the answer!
Chapter completed!
