345 Mental arithmetic
Lost.
Ten breaths ago, Fang Jueming's answer was correct, but he didn't get the result until he was the third to the bottom.
There is a process for the human brain to process information, remember the numbers reported by Yan Jiangguan, form an impression in the mind, and calculate the results, this process is all completed, and it will take about five breaths of time.
However, before I knew it, the excitement of being called out of my name and counting down was much stronger than I imagined.
Even Fang Jueming was stunned for two seconds before he realized what he should do.
Yan 14 only used three breaths......
How did he calculate?
That's too fast!
Fang Jueming didn't want to look back, but his head involuntarily tilted back and glanced at Xu Wen.
He looks very serious, the corners of his eyes droop, the corners of his mouth are down, he looks a little fierce, and this glance is inevitably a little vicious.
"Why is he glaring at you?" Jiang Wangfeng leaned closer to ask in a low voice.
"Hmm......" Xu Wen actually guessed, but he didn't speak, but nodded at Fang Jueming.
Fang Jueming was stunned for a moment, and shook his head back suddenly.
Xu Wen smiled and looked to the other side of himself.
Sun Si and Chen Wannian were tired and nervous, staring at the craftsman, and kept chanting words in their mouths, as if they were praying or reciting something.
"Qiao Zhi!"
"Toβ"
β458+12γ Ten ......"
β470γ β
"Correct. β
One breath!
This is the real second answer. When Qiao Zhi answered correctly, Yan Jiangguan's "ten" was only halfway through, and the end note didn't come out!
This is by far the fastest one. Although his question is relatively simple, this reaction speed is fast enough.
Everyone looked at him together, Qiao Zhi grinned, hugged him around, and smiled a little flatteringly.
"It's hidden. Xu Xihuai lifted his eyelids and said quietly.
"Good luck, good luck. Qiao Zhi said with a grin.
"It's a face-saving experience for our group. Fang Jueming said softly, still feeling a little regretful that this person was not himself.
It doesn't matter, there are still nine wheels to come!
In full swing, the countdown sound is hypnotic.
This was followed by a large wave of elimination, and a small number of them passed the ten-breath test.
Xu Xihuai also passed, just counting down to five, not as good as Qiao Zhi and Xu Wen, but a little stronger than Fang Jueming.
Unconsciously, counting down to a few breaths to answer the question has also become a stage for them to compete.
"Jiang Wangfeng!"
"Here!"
"895+48!10 ......"
β953οΌβ
"Correct. β
Another breath!
Without thinking at all, it was faster than Qiao Zhi, as if the answer was already imprinted in his head, and he just needed to say the result.
This is a real talent, a talent that people can't envy!
Fang Jueming listened to the voice coming from behind him and clenched his fists.
"Tian Jifeng!"
"Here!"
"484+57!ten, nine...... Sixth, fifth ......"
β541οΌβ
"Correct. β
"Sun Si!"
Three names in a row, all of them were called by Xu Wen's group, especially this one, whose arithmetic ability is very poor, and he has been saying that the fourteenth and their group are dragging their feet before. It's his turn, and the score of the Yan group should be pulled down......
"Here!" Sun Si replied loudly, a little nervous, but his speech was quite clear.
"954+89!ten, nine, eight, seven......"
If there are some of these arithmetic problems that are relatively easy and some of which are more difficult, there is no doubt that this is quite a difficult one.
Every two digits add up to ten digits, and the final total is four digits!
According to the practice of a few days ago, this person named Sun Si couldn't answer for enough time, and the countdown of ten breaths was definitely boring.
As a result, when the countdown was to three, Sun Si stuck in the middle and made a sound.
β1043οΌβ
His tail note was raised, with a clear lack of confidence in his voice, and a slight stammer.
Yan Jiangguan's response quickly followed: "Correct. β
Sun Si himself was stunned first, and then he grinned, surprised and delighted, as if he couldn't even believe it.
He turned his head abruptly to look at Yan Fourteen, who nodded to him and returned an encouraging smile, Sun Si smiled even happier, the tiredness on his face was swept away, and he stared at the craftsman with great interest, wishing that it would be his turn next.
As early as when Sun Si said the answer, Fang Jueming had already turned his head to stare at him. He saw Sun Si's full reaction, realized something instantly, and his heart was full of shock.
This is what Yan 14 taught him?
Yesterday, Sun Si didn't know, in such a short time, can he teach such a good effect?
It is indeed Xu Qianjiao.
In fact, up to now, all the exams taught by the craftsmen are the most basic addition, subtraction and multiplication, and there is no division yet.
These things were known to elementary school students in his time, to be precise, most children had learned them before they went to school, at most they couldn't do mental arithmetic so quickly.
But in fact, in his time, there were also many mental arithmetic methods, such as abacus mental arithmetic is one of the quite popular.
What Xu Wen taught Sun Si and Chen Wannian was mental arithmetic, and Tian Jifeng also learned a hand.
However, Sun Si and Chen Wannian were able to calculate the problem with the formula of mental arithmetic, and Jiang Wangfeng was very disappointed and said: "Do you still need to use the formula?
These words were too hateful, and Xu Wen and Xu San beat him up when they pressed him.
Tian Jifeng originally wanted to say that he also felt this way, but when he saw Jiang Wangfeng's fate, he immediately shrunk his neck and coaxed himself.
Sun Si and Chen Wannian worked very hard, they memorized it all night last night, and they were all carrying it on the road today, and they really succeeded in calculating it at this time, which scared everyone.
"It's ...... How did he do it?" Xu Xihuai also noticed, and his eyes widened in surprise.
"I don't know. Fang Jueming said a little stiffly.
He thought they were already ahead of each other, but suddenly the other party caught up again.
Why, does God take care of these people like this?!
I'm not convinced!
According to the convention of the game these days, the difficulty of the problem becomes more and more difficult the later it gets. Our players are much more average, they are cramming, they can't beat us!
The "game" continued, and the voices of Huang Yan's two craftsmen and a random candidate sounded one after another, and the rhythm was amazingly fast.
Soon, all three hundred craftsmen took turns, and in the end 197 remained.
"More than I thought. Xu Wen looked straight ahead and found that the two examiners were looking at each other, on the one hand, they were satisfied, and on the other hand, it seemed that the result was what they expected.
"The second round begins. β
"Yan Fourteen!"
"Here!" The first one was Xu asked, he was stunned for a moment, but he still answered immediately.
"157+487+694!" Yan Craftsman Officer stared at him closely, his expression was serious, and he reported quickly.
Three-digit triple addition?
I didn't take the test the day before yesterday or yesterday.
Moreover, Huang Jiangguan still had an account book in his hand, ready to register everyone's results, but Yan Jiangguan didn't have anything in his hand, and all these numbers were casually reported by him.
In other words, the latter results were also calculated by him on the spot.
This level of mental arithmetic ability is not something that ordinary people can have.
Huang Jiangguan did not forget to recognize people's names, and Yan Jiangguan's super mental arithmetic ability was dual-purpose, these were not ordinary talents, and they were placed in such a team of soldiers.
What exactly is the West Desert going to build?
Or what to do?
Need such a team?
"Ten, Nine, Eight, Seven......"
"Five, Four, Three......"
Craftsman Yan was still counting down, but Xu Wen was a little distracted.
