Chapter 2327 Test your arithmetic
February 2nd, the dragon raises its head.
After Yang Xiaotao woke up in the morning, he was pressed on the chair by the old Taoist, and then an iron pusher rang out on it, with balls of hair falling down in the middle. "Old Dao, is your craft possible?" Yang Xiaotao looked at the big buns of hair falling down, and was a little suspicious of the craft.
The old Taoist smiled, "Don't worry, I used to be in the army, and I worked as a part-time barber."
"Don't worry."
"It would be strange if I don't worry."
< br>Yang Xiaotao muttered, and the boys from Dragon Boat Festival next to him ran over and shouted, very happy.
"Go and go, wash your hands and eat."
Yang Xiaotao sent a few children, and then was interrupted by the old Taoist, "Don't move around, otherwise it will be ugly if it is crooked."
"Don't blame me then."
" >Yang Xiaotao dares not move around, it is related to his appearance, and his hairstyle is very important!
After cutting his hair, Yang Xiaotao hurriedly went to the house to wash his hair and then looked in the mirror.
Okay, this little flat head has nothing to do with appearance.
As it turns out, as long as the dish is hard, there is not much difference between a plate or a bowl!
In the yard, the old Taoist voice came, and the next one continued.
After breakfast, everyone left the yard and walked towards the factory.
Yang Xiaotao took his men to the Ninth Courtyard.
After I came to the office and sat down, I received a call from Han Sanfeng, saying that Wang Kun and the others had made it.
Hearing this news, Yang Xiaotao immediately put down his work and went to the research institute.
Be careful with the Calculator Research Office, Yang Xiaotao was immediately welcomed into it after he arrived.
"Yang's tribe!"
"Teacher Yang!"
There were many people saying hello. Yang Xiaotao nodded to everyone, and then followed Han Sanfeng to Wang Kun and Liu Yongqiang quickly. .
The two of them looked excited, then moved away from the position, revealing a wooden box on the table, which was about twenty centimeters long and ten centimeters tall.
Yang Xiaotao walked up to him, and everyone surrounded him. "Yangbu, this is the small calculator we made." Liu Yongqiang spoke and opened the wooden box.
Yang Xiaotao stepped forward and looked around and found that it looked a bit like the later calculator, but it looked much bigger.
In addition, there are not so many buttons, only horizontal and vertical rows. If you look carefully, you will see that from left to right are 0, 1, 2, and 3.
The following are numbers, then addition, subtraction, multiplication and division, and finally, an equal sign and a box.
Yang Xiaotao guessed that this box should be reset to zero.
In other words, this calculator can only be used to calculate addition, subtraction, multiplication and division, and there are no other ones for the time being.
Perhaps, this is the limitation of technology.
Seeing Yang Xiaotao looking at him, Wang Kun immediately explained, "Yang Bo, we made a simple calculator according to the digital logic circuit!"
"The entire calculator is mainly composed of three main parts, respectively It is the core calculator and controller, display screen, and power supply part! "
" Among them, we use a large amount of high-purity silicon as transistors to achieve our Demand! ”
”This is also the hardest part of the manufacturing process.”
”But we did it.”
Speaking of this, everyone's faces were more proud.
"Through the calculation, we can process addition, subtraction and sum of nine digits, and multiplication and division of five digits!"
"This is the display screen, it is Jin The door power plant is made..."
"This is the power supply. We are now using AC power. In the future, we will change it to DC power. Just use the battery..."
Wang Kun carefully Yang Xiaotao listened seriously and everyone around him showed a novel expression.
Among them, he is the worker involved in the research and development of calculators. He has no specific impression of what calculators do, let alone others!
Yang Xiaotao was prepared for this, and after looking at it for a while, he asked, "How to do it?"
Liu Yongqiang immediately took out the calculator and placed it in front of Yang Xiaotao, "Yang, these are all Button! "
"We are just a preliminary design, and the follow-up will be improved!" "
As he spoke, Wang Kun handed over the machine and Liu Yongqiang turned on the power.
The display screen in front of everyone suddenly shone, and a row of black numbers appeared on it.
Starting from nine, it keeps retreating, and finally coming to zero, there is another flash of flash, and finally there is only one zero on the display screen on the far right.
"Yang Master, this is the normal working state, which means it can be operated!"
When Wang Kun said, Yang Xiaotao hurried forward and asked in the button, "Press directly ? ”
“Yes! ”
Wang Kun nodded, then pointed to the top button, "This is zero, one, two, three..."
"This is the addition, subtraction, multiplication and division symbol, followed by the equal sign, and then the clear button... ”
In fact, Yang Xiaotao can understand without Wang Kun’s explanation.
After Wang Kun finished explaining, Yang Xiaotao looked at everyone and smiled, "How are you all arithmetic?"
The people around him were stunned and didn't understand what it meant.
Finally, Lou Xiao'e, who followed her, said, "Yang Bu, our arithmetic is okay!"
"No matter how you say it is, they are all people who have been to school."
The others around him also heard it. nod.
Yang Xiaotao nodded, "Okay, then let's take the test!"
"Listen."
"What is one plus one equal to?"
"Two!"
Many people shouted out with a smile. At the same time, Yang Xiaotao also pressed the equal number on the calculator, Seeing a number '2' appear on the screen, Wang Kun and Liu Yongqiang were relieved when they saw it.
"Okay, then what is two plus two?"
"Four!"
Everyone shouted again, and 4 appeared on the screen.
"What about four plus four?"
"Eight!"
"Eighty percent eight?"
"Sixteen!"
< br>
Someone just shouted it out and thought it was wrong.
Someone laughed, and then the person who reacted immediately shut up. This was so smooth, but he didn't hear it clearly.
Yang's team doesn't play according to the routine.
At this time, Yang Xiaotao looked at the number on the screen, 64. Everyone also looked at the screen and was very happy.
"It seems that everyone's arithmetic is very good."
"Of course, the premise is to hear it clearly."
Yang Xiaotao joked, then cleared his throat again, "Listen, 6 What is fourteen times sixty-four? "
After Yang Xiaotao asked, some people around him were calculating in their hearts, some were geeking with their fingers, and some were directly calculating with their pens.
But Yang Xiaotao had already stopped at this time and saw the words ‘4096’ appear on the screen.
Wang Kun and Liu Yongqiang looked at each other, both excited.
They have tried this kind of test, and Yang Xiaotao's experiment this time was more shocking to everyone.
"Four thousand,096."
Someone shouted out, and more people nodded.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
However, seeing the display screen in front of Yang Xiaotao, the smiles on everyone's faces disappeared.
Because the numbers above are the same as their calculation results.
But, they took seven or eight seconds, while Yang's troops only took three seconds. "It's correct." Yang Xiaotao asked softly, and everyone nodded.
Many people looked at the calculator.
Yang Xiaotao's operation just now was very simple, especially Lou Xiao'e and others who often deal with numbers. They were already thinking that if there was such a machine, the work in the future would be much easier. "Continue, listen." "What does 4096 multiplying 4096 equal to?"
Yang Xiaotao asked, everyone's faces changed.
Many people scratched their heads because the multiplication of these four-digit numbers has exceeded their computing power.
Some people saw Yang Xiaotao's intentions, and they were even more thinking about seeing if this machine could calculate it.
But someone still took out paper and pen and calculated carefully.
Yang Xiaotao still pressed the button slowly. Every time he pressed it, a number would appear on the screen.
Until the equal sign is pressed, a string of numbers appears.
Everyone looked at the numbers on the display screen and their eyes were dazzled.
So long.
At the same time, I was a little curious. Is it so accurate?
At this time, someone finally calculated the calculation results, and then started to read with the paper, ‘16777216! ’
Every time I read a number, everyone would look at the display.
Until the last reading was finished, everyone was silent for a moment, and then they clapped their hands.
Han Sanfeng suddenly realized that the biggest advantage of this calculator is its speed!
The more complex the arithmetic, the faster it can solve it.
If the results are more accurate, then this calculator can greatly improve the efficiency of certain work.
As for accuracy?
Han Sanfeng is also a computer researcher. Of course, he knows that as long as the computer is well set, it will be better than humans.
When Han Sanfeng thought of this, she felt a little regretful.
I regret not turning on the integrated circuit research of the computer as soon as possible.
'It's okay, it's not too late! ’
I made up my mind that after today, the focus of the research center will be shifted.
No matter how well the transistor computer is researched, it is just chasing on the lower runway.
If you want to catch up with your opponent, you have to think of some external moves.
On the other side, Yang Xiaotao nodded, and then recognized the person who calculated it in the end. He was the first group of students who entered the classroom at Yangjiazhuang Primary School.
Yang stick.
This child left a deep impression on him back then.
Because I am young, I can't keep up with the pace when I go to school.
When Yang Xiaotao and Ran Qiuye were hesitating whether to let him participate.
Later, I participated, just pretending to be like making soy sauce and seeing the world.
But I didn't expect that this kid was very successful and actually passed the exam.
Although he was the last one and just got stuck in the passing line, he was also in junior high school.
Later, Yang Xiaotao did not pay special attention to the development of these students, but Ran Qiuye contacted him for a long time.
"Let's go on."
Yang Can was stunned, and then immediately said, "Okay Teacher Yang."
Everyone didn't care about Yang Can's name, and Everyone knows about Yangjiazhuang.
"What is the difference between 16777216 by 32?"
After hearing this, Yang Park quickly took the notebook and pencil to the side and started calculating.
No need to say this time Yang Xiaotao, Han Sanfeng came to the calculator, started typing the content, and then pressed the equal number.
524288!
Han Sanfeng read out the numbers, and then everyone looked at the young man lying on the table not far away.
At this moment, Yang Pao sweated on his forehead, especially when he heard the sound from behind and the attention he felt, which made him feel a feeling of being peeped.
At the same time, he didn't want to make a fool of himself in front of Teacher Yang, because that was to embarrass Teacher Yang.
The operation of division is more difficult than multiplication, because multiplication and subtraction are also required.
So, after more than two minutes, Yang Jian walked up to him with the notebook and shouted loudly about the calculated results.
After a moment, Yang Xiaotao applauded gently.
Then, the applause was warm.
"It's pretty good."
Yang Xiaotao smiled at Yang Jian, then took out the pen in his pocket, "This is a reward for you."
Yang Jian was stunned, and then Be careful to take it with the urging of the people around you. "Reward you is not only because you calculate correctly, but also because you are willing to calculate." "In this world, many things seem difficult, but I really wait to do it, You will find it is not as difficult as you imagined."
Although Yang Xiaotao said this to Yang Jian, everyone present remembered it in their hearts.
In particular, Han Sanfeng felt that Yang Xiaotao was waking him up, and he made up his mind to form a team as soon as possible.
The second is Wang Kun and Liu Yongqiang, who are the people who feel the most.
When Yang Xiaotao found them, they explained the situation, and they still felt that it was a bit "unbelievable".
But later, I persisted until now.
Now, isn’t it a success? "Actually, the most difficult thing is to convince yourself to take the first step!"
