Chapter 162 Mental Arithmetic Test
On July 7th, Zhou Ming rested at home for a day. On July 5th, Zhou Ming took the high-speed train to NJ again, and took part in the mental arithmetic ability test of "The Most Powerful Brain" in Tianhe Gymnasium.

Zhou Ming called Wang Yunqing, the chief director of "The Most Powerful Brain" yesterday, and asked him if he could challenge the mental arithmetic project. He is also good at mental arithmetic.

Wang Yunqing was overjoyed, because the column team of "The Most Powerful Brain" has recently been frantically looking for mental arithmetic experts across the country, but they just can't find a mental arithmetic expert who has the strength to be on the table.

Especially two years ago, Chen Lanlan, the "Queen of Mental Arithmetic" of Country Z, tied with Hiroaki Ishiya, the "Emperor of Mental Arithmetic" of Footbath Country, and announced her retirement. They disappeared collectively. I don't know if it was because Hiroaki Ishiya was really too strong, or because he was afraid of being ashamed if he lost. In short, no one who was strong dared to go up.

Now that Zhou Ming wanted to go on the initiative, Wang Yunqing planned to give him a chance to be on stage again, but this "Magic Cube King" suddenly studied "Mental Arithmetic" across fields.

Test room.

“3216+5024+5324+5245+1255，这是五个四位数的加法，选手请作答。”

After 3.5 seconds, Zhou Ming showed the answer board in his hand: 20064, and said to the female science assistant in front of him: "Addition is too simple, change to a more difficult multiplication."

"Okay, the following is a multiplication of nine times five digits, 165465456×46456, please start answering!"

In less than 5 seconds, Zhou Ming showed the answer board in his hand again: 7686863223936, and said: "It's not difficult enough, change to a more difficult one!"

"The answer is correct. The next step is a multiplication of seven digits by eleven digits. The degree of difficulty is very high. Please see the question board on the big screen."

Keli pointed to an electronic screen on the wall of the test room, and Zhou Ming looked at the question board in the center of the screen:
6314859 × 87420397516
After the question board displayed the question, Zhou Ming first printed the two sets of numbers into his brain in one second, then turned his brain on for two seconds, began to write, buried himself in the answer board to answer quickly, and wrote down a series of numbers:
552047484037490244
After Zhou Ming pressed the timer and compared the answers, the science assistant couldn't help shouting: "It's absolutely correct, less than seven seconds, it's too fast, the calculation is too fast!"

The director Wang Yunqing on the side also widened his eyes, stared at him like a monster for a while, and then asked: "Zhou Ming, how long have you been practicing mental arithmetic? You have reached the level, and you are fully qualified to be on "The Most Powerful Brain", and have a PK with the 'Mental Arithmetic King' Hiroaki Ishiya of the Foot Pen Kingdom!"

Zhou Ming chuckled: "I practiced this project together with Rubik's Cube, probably for more than a month..."

"One month, I have practiced to this level..."

Wang Yunqing opened his eyes wide and looked at him in disbelief. From which planet did this monster fly to Earth? What is your purpose for coming to Earth?
With some complaints in his heart, Wang Yunqing reminded him at the right time: "Zhou Ming, your level of multiplication of large digits is very good, but Hiroaki Shiwu is best at division of large digits, and you are also strong in division and mental arithmetic. strength?"

On the surface, multiplication mental arithmetic and division mental arithmetic should be equally difficult, except that one is a forward operation (multiplication) and the other is an inverse operation (division). However, because of the different ways of thinking of the human brain, some people are good at forward operations, while others People who are good at inverse calculations and forward calculations account for the majority, and those who are good at inverse calculations are only a very small number.

For example, people's handed habits, there must be much more right-handed than left-handed.

Zhou Ming smiled and said, "No problem, but I think division is easier than multiplication. It will save a lot of digits, and the answer will be faster... If you don't believe me, just come up with a question and test it out."

"The following is a division of eleven digits by six digits, please prepare to answer."

÷ 26243504882 567329
46258
After a while, Zhou Ming quickly wrote out the answer and pressed the timer.

"The answer is correct, it took 3.8 seconds!"

"The next question is more difficult. It is a division of a sixteen-digit number by a nine-digit number. Please watch the questions on the question board for answers!"

÷ 2191669850969445 589240137
3719485
After the question appeared, Zhou Ming wrote the correct answer in an extreme time.

"It took 5.7 seconds, exactly right!"

After answering two questions in a row, the director Wang Yunqing was completely uneasy, and said loudly to Kezhu: "Quick! Take the division question that Hiroaki Ishiya hit the brain king last year, let Zhou Ming do it too, and see how much he wants." It will take a long time to figure out the answer!"

"Director Wang, you mean, the division of the eighteen-digit number by the eleven-digit number, which was calculated by Hiroaki Ishiya in more than seven seconds?"

Kezhu opened his pretty eyes and asked in surprise, last year's Brain King Challenge was unforgettable. Although Ishiya Hiroaki failed to win the Brain King trophy, the powerful strength he showed through this division problem still made people feel ashamed. Impressed by all.

"Yes, yes, bring this question over quickly, let Zhou Ming try it, and see if he can break Shiwu Hongming's record!"

Wang Yunqing saw hope. He watched the program "The Most Powerful Brain". In terms of mental arithmetic, he was suppressed by the "Mental Arithmetic King" of the Footpen Kingdom for three consecutive years. Now he has the hope of turning around.

Zhou Ming, the ordinary young man in front of him, brought him a shock and surprise that far surpassed that of any contestant who had appeared in "The Most Powerful Brain".

This young man is extremely confident and arrogant!But he was never afraid of challenges. In the process of challenges, he could always use his strength to the limit of human beings to prove that those big words he released were not lies!He can also afford to let go, disdain to care about the weak, and boast that his brain is the strongest brain, and he will defeat all opponents!Wang Yunqing didn't really believe it, he only thought he was young and vigorous, but now, he really started to believe it.

"Eighteen digits divided by eleven digits, more than 7 seconds, I remembered, I have also watched this episode, it seems to be 7 seconds 48..."

Zhou Ming was also deeply impressed by the Brain King Challenge in the final episode of the third season of "The Most Powerful Brain". In this episode, the winner of the Brain King trophy at the end seemed to be a 15-year-old boy named Chen Zhiqiang, nicknamed "Supernova". boy".

The technicians quickly found the question and entered it into the background system of the question board.

The assistant with a sweet voice also gently reminded: "Zhou Ming, please read the question board carefully. This question is very difficult. I hope you will use your best strength to solve this question in the fastest time. Write The correct answer." After finishing speaking, the assistant gave him a quiet wink.

"OK!"

Zhou Ming made a gesture, concentrated his attention, and stared at the countdown on the question board, 3, 2, 1, the question is displayed!
÷ 425688500537940536 74169305821
Brush brush!
Boom!
Press the timer, 5.35 seconds.

Zhou Ming had no reservations, and almost immediately after scanning the questions, he wrote down his answer on the answer board:
5739416
Wang Yunqing, who was standing aside, quickly snatched his answer board and asked the staff to announce the correct answer: 5739416.

"Correct, absolutely correct!"

Seeing the time taken by the timer Zhou Ming, Wang Yunqing was stunned, as was the beautiful woman Ke Li next to him, and the other staff in the testing room were also stunned. Then they all looked at the man with adoring gazes, and everyone's faces were shocked. All of them were extremely excited.

"Crack, crack~"

"Pa la pa la pa la~"

I don't know who applauded first, and then the applause in the test room was unstoppable for a long time.

"Xiao Zhou, you are the great savior of our "Most Powerful Brain", those who question and insult "Most Powerful Brain" every day, can finally shut up now! Go! Say nothing, Xiao Zhou, I invite you to a big meal!"

The red-faced director Wang Yunqing hugged Zhou Ming's arm and said, then swept to the eight or nine staff members in the testing room, waved his hand, and said generously: "Let's go, you all go together, the director is in a good mood today, Let's have a big meal together!"

"Long live Director Wang!"

Cheers in the testing room!
……

At noon, at a large seafood restaurant in the urban area, Wang Yunqing had a meal worth over ten thousand yuan. Halfway through, Wang Yunqing answered the phone. After the meal, Wang Yunqing, who was slightly drunk, pulled Zhou Ming aside and said:
"Xiao Zhou, the program team has just adjusted the recording schedule. On July 7th, the eighth issue of "The Most Powerful Brain" will arrange for you to appear again! To meet the two apprentices sent by Hiroaki Ishiya, don't underestimate him! These two apprentices, after returning, practice mental arithmetic a lot, and face the battle in the best condition! Also, your body can’t have the same accident as last time, it’s best to arrive in NJ in advance, and the program team will arrange meals for you And accommodation... Also, you have to keep your phone open and make sure you can contact me at any time!"

"No problem, Director Wang." Zhou Ming nodded.

Maybe he still felt unsafe, so Wang Yunqing whispered in his ear again:
"Xiao Zhou, if there are no accidents in the recording of the eighth issue of "The Most Powerful Brain", you also successfully defeated the two apprentices of Hiroaki Ishiya, the column team decided to give you a bonus of 30 yuan! In addition, you The appearance fee of the program has been increased to 5, that is to say, as long as you participate in the recording of the program, you can get 5 even if you don't participate in the challenge...Xiao Zhou, let me tell you in secret, the appearance fee of brother Shui Wang Yiheng is also this amount, Our column team is very optimistic about you."

"Oh~ there is such a thing?"

Zhou Ming's eyes lit up, and he immediately patted his chest to make a promise: "Director Wang, please don't worry, even if the sky falls, I promise to come to the show and try to arrive in NJ one or two days in advance... In this way, you should rest assured Bar?"

Wang Yunqing raised his head and laughed loudly: "Don't worry, absolutely don't worry!"
