Because the answer is remarkably correct.

Not only is it correct, Zhong Shuyu's algorithm process is not wrong at all, and it is even easier than his algorithm process, which makes him feel that he can solve it like this.

In Wu Guoan's shocked, incredulous emotions.

Zhong Ling has already begun to solve the next problem.

It's not that she doesn't review the topic, it's not that she doesn't think.

But when she was off the stage just now, she had already seen the questions of the previous questions, and as soon as her eyes swept over, her brain automatically began to run the algorithm.

This will come up, and naturally just write out the algorithm answer.

As Zhong Ling solved the second question, Wu Guoan's shock never stopped.

He really wanted to find mistakes from some angles, such as Zhong Shuyu cheating, and he knew the answers in advance.

But these are obviously impossible, because these questions are not exactly the same as the model questions in the teaching book, but he has corrected them according to the questions in the teaching book.

For example, this first question he asked.

Today, there are those who do good deeds and those who do not take 90 steps, those who do not do good deeds take fifty steps, and those who do not do good deeds take 100 steps first.

This changed the original step number, and the calculated answer was naturally different.

If you can't, there's no chance of cheating.

However, if there is no cheating.

Wu Guoan couldn't understand how he could progress so fast in just over a month? Could it be that Zhong Shuyu has been guided by a famous teacher for more than a month? ?

In Wu Guoan's suspicious, complex and unspeakable emotions.

The students below are roughly divided into two types.

One is the students who can do this question, and they look at the perfect answer above and their hearts are fried.

That's right, it's done right!

And the other kind of thing that I can't do, seeing the stunned and ugly expressions of many students, I am still there and sure that I must have done something wrong, and they will be like this.

I'm still full of ambition and waiting for a lesson in the precept ruler.

……

In the blink of an eye, Zhong Ling had already solved the fifth question.

That is the last question from Wu Guoan.

This last question is naturally the most difficult question Wu Guoan, although it is also the content he has taught, but he is particularly complicated, beyond the difficulty at this stage.

When Zhong Ling saw this question, the tip of his pen paused slightly.

Seeing this, Wu Guoan's eyes suddenly lit up, and it was finally difficult for him?

However, Zhong Ling immediately disappointed him.

She took the charcoal and immediately began to write.

She paused just now, thinking about whether she wanted to hide it, step by step, and moisturize things silently.

After all, it's only the first day.

But this thought only passed by slightly, and was abandoned by Zhong Ling.

There's nothing to hide, the edge is exposed!

One day earlier, one day later, the final result is the same, so why is it necessary to take it slowly?

And she didn't plan to go up step by step.

It is good to be exposed in the morning and evening, and it is also a good thing to show the edge early.

As for how others are shocked and hard to believe, what if they slander her?

That's their thing!

If she can't even bear this, how can she talk about future success.

Soon, Zhong Ling wrote out the final answer.

After sketching the last stroke, Zhong Ling's hand hung down, looked sideways at Wu Guoan and said, "Sir, the five questions have been solved, please check if you have done it correctly." ”

Wu Guoan looked at Zhong Ling's eyes as clear as water for two seconds, turned his gaze to the speakerboard, and swept over the answers one by one.

Finally, his gaze rested on the fifth question.

As soon as he raised his hand, he pointed to the fifth question with a ring ruler, looked at Zhong Ling expressionlessly and asked, "Why do you solve this question like this?" ”

Hearing Wu Guoan ask.

The students who were shocked by Zhong Shuyu's correct answer just now suddenly settled down a little.

If you ask this question, you must be wrong!

But I think it's also, how can Zhong Shuyu answer correctly!

This question is so complicated, they haven't solved it yet, and they are still pondering, Zhong Shuyu must have scribbled an answer.

Thinking like this, they couldn't help but look at Xia Xinjue, who had the best arithmetic score in the whole grade.

But I saw Xia Xinjue, who had always been cold and arrogant and expressionless, staring directly at Zhong Shuyu's body at this time, with a scorching eye.

The students were dumbfounded.

Huh? Xia Xinjue, what kind of expression is this?

Could it be that Zhong Shuyu did the right thing?

Otherwise, he shouldn't have this expression!

Because Xia Xinjue is an arithmetic maniac, only in the face of complex arithmetic and people who are good at arithmetic will he show a different kind of fanaticism.
