Chapter 170: Lightning mental arithmetic

　　 The four people walked onto the stage, and an introduction about the four people sounded at the recording scene.
The personal data of Annoy and Cheng Nuo have long been familiar to viewers in China. Their main concern is the data of two players from the island country.
"Igawa Beelang, 16 years old, from the island country of Newbiah High School, has won the island country abacus mental arithmetic contest three times in a row in the primary and middle school group championship."
"Teng Keesho, years old, from Tokyo University in the island country, is a god-level figure in the island country's fast calculation industry. Since the age of 14, he has won 17 national quick calculation championships, a global quick calculation championship, and the 68th abacus mental arithmetic total score individual Overall first place, the first prize of the 5th Abacus Mental Arithmetic Competition of the World Abacus Mental Arithmetic Federation."
Obviously, compared to Betsu Igawa, the award that Fuji Terue has won is heavier.
It also proved that Fujiterue's quick calculation strength was much higher than Igawa Belan.
After the introduction of the information, on the big screen behind the stage, as usual, the six-dimensional ability radar chart of the four players appeared.
The other three players are okay. The six ability radar charts all have a quick calculation power of 4.5 points or more, and the other five abilities are not outstanding.
Ke Cheng Nuo's six abilities radar chart...It is still that unreasonable.
The calculation power is 5.0 points, let alone this.
The remaining five items, observation, memory, space, creativity, and reasoning, all have 5.0 points.
The one hundred island audiences in the auditorium saw Cheng Nuo's full six-dimensional ability radar chart, and they lost consciousness for a moment.
Reproduce the hexagonal warrior!
They suddenly remembered that in the international table tennis arena, there is a demon-like figure from China who is also a hexagonal warrior.
She swept the entire table tennis world, beating countless island country table tennis players. It left a huge shadow on the island audience.
She is sexual and arrogant!
This time, they once again saw a hexagonal warrior on the stage of the strongest brain.
Is it possible that this Chinese player named Cheng Nuo can bring the people of the island nation the fear that the Great Devil came to the world.
The island audience in the auditorium is not clear.
But the only certainty is that the island team is not easy to play in this game!
At least, it won't be as easy as they thought.
The four players are still the same as the original entertainment game. Two Chinese players stand on the left hand side of Teacher Jiang, and the two island players stand on the right hand side of Teacher Jiang.
After a few very official kind words, Mr. Jiang began to introduce the projects challenged by the four contestants this time.
All four are players who are good at quick calculations.
Uh... I was wrong. All three players are good at quick calculations, except Cheng Nuo.
Cheng Nuo is not only good at quick calculations, he is also good at Rubik's Cube and memorizing...
Most importantly, this guy is good at acting!
Keke... back to the subject.
Since the information of the four is related to quick calculations, then this time, the project the four challenged must be quick calculations.
Project Title: Quick Calculation Battle!
The competition is divided into three stages.
One person is eliminated at each stage, and the player who stays at the end will win the game from which country belongs to the player.
First, the first stage: Lightning mental arithmetic!
In the question bank, there are reminders for the difficulty of 3 to 20 stars for players to choose.
Four contestants, in order, take turns choosing questions of different difficulty to answer.
The difficulty of the question is determined by the contestant.
A correct answer will win the corresponding star value, and a wrong answer will subtract the corresponding star value.
There are three rounds in total. After three rounds, of the four players, who has the lowest star value will face the fate of being eliminated!
Next, what Cheng Nuo and the others are conducting is a competition of lightning mental arithmetic.
"Okay, I have a coin in my hand, with the flag of China on the obverse and the flag of the island nation on the reverse. Which country chooses the challenge first is determined by the coin in my hand. Which side is up, which one? The country chooses the topic first."
Teacher Jiang took out a coin from his pocket.
Then he threw it high, landed on the back of Teacher Jiang's hand, and covered it with the other hand.
"Which country was the first to fight?"
While talking, Teacher Jiang removed the palm of his hand covering the coin, slowly revealing the national flag of the island country.
"Okay, it's the island team player's first appearance."
Teacher Jiang gestured to the players of the island national team, "You two can discuss which player chooses the challenge first!"
This challenge project, in the strict sense, will come, and there are certain advantages in the second-hand countries.
After all, you can adjust the difficulty of your own choice of questions based on the number of stars the opponent chooses.
However, this advantage will only appear when the players of both sides are balanced.
Because...if the opponent's strength is strong enough, answering questions later will not be an advantage.
Instead, it is likely to become a huge pressure.
The two players on the island nation’s team now have such a mindset.
They believe that with their strength, they are enough to crush the two of the Chinese team.
To them, it doesn't matter whether they are first or second.
"I'll come first." Betsu Igawa shrugged, and said to Fuji Terue.
Fuji Teruee half leaned on the challenge chair and smiled confidently, "Okay, then you come first. I'll come to the back. The two of the Hua Guo team are not afraid..."
Fuji Teruesuo gently shook his head.
One is a little girl who is only twelve years old, and the other is a rookie who has never won any quick calculations.
The lineup sent by the Hua Guo team...
Ha ha!
I am afraid that I have already given up this point strategically.
On the big screen, the difficulty of lightning mental arithmetic and the corresponding star value are displayed.
Jingchuan Bielang looked up at the big screen and said the difficulty of his choice.
"I choose three digits plus five seconds."
Three-digit number, one-star difficulty.
Addition, one-star difficulty.
Six seconds, seven-star difficulty.
Total difficulty stars, nine stars!
This is a moderately difficult question type.
Of course ~EbookFREE.me~ this medium level of difficulty is for professional quick calculators.
If you let ordinary people do it, let alone nine stars, nine hundred stars are not too much.
Beelan Igawa, who appeared first, didn't know if he was seeking stability or his strength was indeed the case, so he chose a nine-star topic.
The backstage selects a question that matches the question type from the question bank.
Beelang Igawa took a deep breath and stepped into the challenge position. Looking up at the big screen.
3! 2! 1!
454!
547!
234!
...
201!
Lightning mental arithmetic problems appear!
Each set of questions is composed of 20 numbers.
The six seconds selected by Belan Igawa means that all 20 numbers will appear on the big screen within 6 seconds.
On average, a number will appear on the big screen every 0.3 seconds.
what is this concept?
The time it takes for a person to blink each time is about 0.2 to 0.4 seconds.
In other words, during the lightning mental arithmetic process, if you accidentally blinked.
It is very likely that a number will be missed.
Therefore, players need to stare at the screen without blinking. 8)
