That is, the two sides of the competition take turns to solve the problem, and after the problem is finished, the two people start to solve the problem together, and the side with the shorter time to solve the problem and the correct answer will accumulate one point, and if the answer is wrong, the points will be added to the other person.

And if someone can't answer the answer, then the score will be added to the questioner.

Whoever accumulates 10 points first wins.

This kind of competition is very focused and adaptable, and it also examines the knowledge reserve and brain of the contestants.

In this kind of arena, the quickest way to win is that she can do all the questions that others make, and she can't solve any questions that others can.

The order at the beginning was determined by guessing boxing, but last night Song Yi promised Zheng, so it was Zheng who asked the question first.

There was two minutes to read the question before starting to answer the question, and Song Yi yawned, looking lazy.

She had just accidentally eaten a little too much, which caused her to be very sleepy and want to sleep now.

Xu Yin glanced at the time.

"Five minutes is up, and now the players on both sides can start answering questions."

Before Xu Yin's words fell, Song Yi and Zheng opened the cap of the pen in unison and began to solve the problem.

This knife topic is not very difficult for Song Yi, and the time she just watched is enough time for her to sort out all the information for calculation, but her luck is not very good.

Oil-based pens don't get ink anymore.

"There's something wrong with this oil-based pen." Song Yi said simply, and then took a new one.

At this time, Zheng had already finished writing the first line of numbers and began to calculate.

He didn't dare to underestimate Song Yi anymore.

So he went all out, grasped every minute and every second of calculation, and must score this point in front of Song Yi.

I couldn't find any other oil-based pens all of a sudden, and the other teachers were obviously more anxious than Song Yi, so they quickly went to the laboratory next door and got a new oil-based pen back.

By the time Song Yi opened the cap of the pen again, Zheng had already finished counting.

"I'm done!"

Song Yi was successful in writing.

Zheng's speed was beyond her expectations.

But it doesn't matter, that's what makes it more interesting.

If he's really a vegetarian, it's too boring to compare.

Hearing Zheng say this, Shaoyin and Xu Yin both came up to see Zheng's solution.

"There is no problem, Zheng gets one point."

Zheng exhaled deeply.

It's already a point!

Song Yi glanced at classmate Zheng without a trace, then picked up the blackboard eraser to erase the topic of classmate Zheng, and began to write the topic that he had already thought of.

Song Yi has been cheated on this topic, it is not only difficult, but also has many traps, and it is easy to be taken to the ditch by it if you are not careful.

Zheng started thinking when Song Yi wrote the topic, and by the time Song Yi finished writing the topic, he already had a general idea.

By the time Xu Yin announced that the time was over and he had already figured out how to solve the question.

Song Yi's oily pen had water this time, but she found that Jin couldn't write on the blackboard.

Song Yi: "......"

The teachers who were standing in the corner and watching the battle situation slowly frowned.

Song Yi's oil-based pen ran out of ink in the first game, but he couldn't write after the ink in the second game.

How bad Song Yi must be, this thing is one after another, it is clear that he can't get along with her and doesn't let her write.

Is this really just a coincidence caused by Song Yi's bad luck?
