Lightning mental arithmetic questions with a total of nine-star difficulty.

20 numbers appear on the large screen one by one speed every 0.3 seconds.

After 6 seconds, all 20 numbers appear.

Ikawa from the island team tilted his head, frowned and thought for a second or two, then brushed a few times and gave his own answer on the answer board:

6254!

Then he immediately turned around, turned his back to the challenge station, and signaled to answer Teacher Jiang to finish his answer.

The Lightning mental arithmetic project, after the topic is released on the large screen, only five seconds will be left for the contestants.

In other words, if the contestant does not turn around and signs that the answer is completed within five seconds, no matter whether the numbers on the answer board are correct or wrong, they will be considered to have failed to answer.

After Ikawa Beiran signaled that the answer was over, Kosuke, who had long legs, immediately walked up and blocked Ikawa Beiran's answer board with a cover, and took it to the host, Teacher Jiang.

Teacher Jiang smiled and said, "First of all, please give the correct answer to this question on the big screen!"

A four-digit number appears on the large screen.

While signaling to Kesuke, Teacher Jiang said to the audience, "Is the answer of the player Beiro Ikawa is correct? Let's look at it one by one."

Auditorium.

All the island audience held their breath and focused, holding their hands tightly in front of their chests, and staring at the answer board in the subject's assistant on the stage without blinking.

"Ikawa-kun, you must answer correctly!"

The island audience is praying in their hearts.

“6! Correct!”

“2! Correct!”

“5! Correct!”

“4! Correct!”

With four numbers, Ikawa Beilang’s answers are all correct!

"Congratulations to the player Beiro Ikawa for taking the lead in winning nine points!" Teacher Jiang congratulated.

Ikawa Beilang raised his clenched fists, his face turned red, he bent down and growled, and his excitement and excitement were revealed...

If I didn't know that, I would probably think he had won the game!

The island audience tried hard to applaud Ikawa Beiran's performance, while glancing proudly at the Chinese audience next to him.

It means: Seeing that there are no contestants in our island country, the speed calculation level is just as good as the filming level!

In response, the Chinese audience rolled their eyes and thought they didn't see it.

Haha, it’s only 9 stars difficult, what’s the point of showing off? Wait for a while and let you see what it means to... the show of flowers!

On the stage, the competition continues.

After Beyawa Ikawa stepped down from the challenge stage, Fujikie chose his question type difficulty.

Four digits, two stars of difficulty!

Mixed with addition and subtraction, two stars of difficulty!

Six seconds, seven stars in difficulty!

Total difficulty, eleven stars!

The difficulty coefficient is two more stars than Ikawa Beilang.

Fujikiyashi stepped onto the challenge stage with great confidence.

Five minutes later...

"Congratulations to Fujikawa for getting 11 points!" Teacher Jiang said loudly.

Smack sex~~

The island audience even more vigorously applauded.

A good start, a good start!

In the first round, no one answered the wrong answer, and he won nine and eleven points respectively.

This is undoubtedly a shot of a heart attack for the island team.

so……

All the pressure was transferred to the Chinese team!

Challenge chair.

Cheng Nuo turned sideways and discussed with An Nuoyi in a low voice, "Nuoyi, who will get on the first place?"

"Big brother, I'll do it first!" An Nuoyi clenched her fist, and her tight little face was full of fighting spirit. "Nuoyi will never disappoint her big brother!"

"Okay, then you come first, I'll fight the formation!" Cheng Nuo smiled casually, and watched An Nuoyi take a small step and walk to the challenge stage.

An Nuoyi stood in front of the challenge stage, tilted her little head, held her fingers in her mouth, and tilted her head. After hesitating for two or three seconds, she gave her own choice.

“I chose to add and subtract six digits to mix for four seconds.”

Annoy's extremely crisp voice echoed in the studio.

Six figures, four stars in difficulty!

Add or subtract mix, difficulty two stars!

Four seconds, nine stars of difficulty!

Total difficulty, fifteen stars!

hiss--

When the difficulty star count came out, everyone present, not only the audience, but also the contestants, looked surprised at the petite figure standing in front of the challenge stage.

Fifteen stars!

This difficulty is four stars higher than the eleven stars of the island country's Fujikiya contestant!

Moreover, according to the information, Annuoyi is just a primary school student...

Are all primary school students so scary nowadays?!

"Don't worry, don't worry, the Chinese team did this just to attract attention. This little girl must have done something wrong. She must have done something wrong..."

Nowadays, the audience in the island country can only use such words to comfort themselves.

On the challenge chair, Cheng Nuo did not recover from An Nuoyi's choice of question types for the time being.

"This little girl looks like I underestimated her." Cheng Nuo shook his head and smiled faintly.

"Nuoyi, are you sure you choose the question type of this difficulty?" Teacher Jiang was obviously the same as everyone's thoughts, so he confirmed An Nuoyi again.

"Yeah!" An Nuoyi nodded heavily, "Teacher Jiang, I'm sure!"

"Okay, then the challenge will begin right away!"

As soon as Teacher Jiang finished speaking, a three-second countdown appeared on the large screen again.

An Nuoyi tightened her face, opened her big eyes, and stared at the big screen without blinking.

3!2!1!

The topic appears:

147887!

-154572!

218779!

...

-872455!

What can four seconds do?

It can be said that if you are given a calculator, you may not be able to finish a digit in four seconds! Not to mention calculating it.

What Annuyi needs to do is to add or subtract the numbers that appear on the screen and the previously calculated numbers within 0.2 seconds of each number appearing.

0.2 seconds? I'm afraid that the fastest man in the world may not be so fast!

After all the 20 numbers were displayed on the large screen, An Nuoyi quickly wrote down his answer on the answer board without any hesitation.

"Okay. Let's take a look at the answer to this 15-star difficult question chosen by Annuoyi is correct?"

The correct answer to this question has been given on the large screen:

797942!

A six-digit number.

Teacher Jiang also asked the beautiful female assistants on the side to verify An Nuoyi's answer one by one.
