Chapter 2327: Test Your Arithmetic

On February , the dragon looked up.

When Yang Xiaotao got up in the morning, the Taoist priest pressed him on a chair, and then an iron razor made a clattering sound on his body, with clumps of hair falling down in the middle.

"Master, is your craft good enough?"

Yang Xiaotao looked at the large clumps of hair falling down and felt a little skeptical about the old Taoist's craftsmanship.

The old Taoist smiled and said, "Don't worry, I was a part-time barber in the army before."

"Do not worry."

"I'd be surprised if I felt relieved."

Yang Xiaotao was mumbling to himself, and a few boys from the Duanwu group nearby ran over and shouted, looking very happy.

"Go, go, go, wash your hands and go eat."

Yang Xiaotao was sending a few children away when he was interrupted by the Taoist priest, "Don't move, or it will be ugly if it gets crooked."

"Don't blame me then."

Yang Xiaotao didn't dare to move. It was related to appearance and hairstyle was very important!

After getting his hair cut, Yang Xiaotao hurried into the house to wash his hair and then looked in the mirror.

Well, this short flat head has nothing to do with appearance.

It turns out that as long as the food is solid, it doesn’t make much difference whether it’s on a plate or in a bowl!

In the yard, the voice of the old Taoist priest was heard, and the next one continued.

After breakfast, everyone went out of the yard and walked towards the factory.

Yang Xiaotao took his people to the Ninth Hospital.

Not long after I sat down in the office, I received a call from Han Sanfeng, saying that Wang Kun and his team had made a small calculator.

Upon hearing the news, Yang Xiaotao immediately put down his work and went to the research institute.

At the Careful Calculator Research Department, Yang Xiaotao was immediately welcomed inside upon his arrival.

"Yang Department!"

"Teacher Yang!"

Many people greeted him. Yang Xiaotao nodded to everyone, then followed Han Sanfeng and quickly came to Wang Kun and Liu Yongqiang.

The two men looked excited, then made way, revealing a wooden box on the table, about 20 centimeters long and wide, and about 10 centimeters high.

Yang Xiaotao walked up to him and everyone gathered around him.

"Minister Yang, this is the small calculator we made."

Liu Yongqiang started to introduce and opened the wooden box.

Yang Xiaotao walked forward, then looked around and found that it was a bit like the calculators of later generations, but it looked a lot bigger.

In addition, there are not so many buttons, only four rows horizontally and vertically. If you look closely, from left to right they are 0, 1, 2, 3.

Below are numbers, followed by 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 for addition, subtraction, multiplication and division, and no other functions.

Perhaps this is the limitation of technology.

Seeing Yang Xiaotao looking at him, Wang Kun immediately started to explain, "Director Yang, we made a simple calculator based on digital logic circuits!"

"The entire calculator is mainly composed of three main parts, namely the core arithmetic unit and controller, the display screen, and the power supply!"

"For the arithmetic unit and controller, we used a large amount of high-purity silicon as transistors, in accordance with the design requirements, to meet our needs!"

“That’s also the hardest part of manufacturing.”

“But we did it.”

Speaking of this, everyone's faces showed more pride.

"Through calculations, I can handle addition, subtraction and sum of numbers below nine digits, as well as multiplication and division of numbers below five digits!"

"This is a display screen, made by the Jinmen Mechanical and Electrical Factory..."

"This is the power supply. We are currently using alternating current. We will switch to direct current in the future and use batteries..."

Wang Kun explained the situation in detail, Yang Xiaotao listened attentively, and the people around him also showed curious expressions.

Among them, he was the only worker involved in the research and development of the calculator, and he had no specific impression of what a calculator was used for, let alone other people!

Yang Xiaotao was prepared for this. He looked at it for a while and asked, "How do I do it?"

Liu Yongqiang immediately took out the calculator and placed it in front of Yang Xiaotao, "Minister Yang, these are the buttons!"

"This is just a preliminary design, and we will improve it later!"

As they were talking, Wang Kun handed over the machine and Liu Yongqiang turned on the power.

The display screen in front of everyone suddenly lit up, and then a row of black numbers appeared on it.

Starting from nine, it kept moving backwards, and finally reached zero. There was another flash, and finally there was only one zero on the far right side of the display.

"Director Yang, this is the normal working status, which means it can be operated!"

As Wang Kun was talking, Yang Xiaotao hurried forward and asked the button, "Press it directly?"

"can!"

Wang Kun nodded, then pointed to the top button, "This is zero, one, two, three..."

"These are the symbols for addition, subtraction, multiplication and division, followed by the equal sign, and then the reset button..."

In fact, Yang Xiaotao could understand it without Wang Kun’s explanation.

After Wang Kun finished explaining, Yang Xiaotao looked at everyone and said with a smile, "How are you doing with arithmetic?"

The people around were stunned and didn't understand what it meant.

Finally, Lou Xiao'e, who followed, spoke up, "Director Yang, our arithmetic is okay, right?"

"After all, they are all educated people."

Others around nodded after hearing this.

Yang Xiaotao nodded, "Okay, let me test you guys!"

"listen."

“What does one plus one equal?”

"two!"

Many people shouted with laughter. At the same time, Yang Xiaotao also pressed the equal sign on the calculator, and a number '2' appeared on the screen. Wang Kun and Liu Yongqiang both breathed a sigh of relief when they saw it.

"Okay, so what's two plus two?"

"Four!"

Everyone shouted again, and the number 4 appeared on the screen.

"What about four plus four?"

"Eight!"

"Eighty-eight?"

"sixteen!"

As soon as someone shouted it out, I felt something was wrong.

Some people laughed along, and then those who reacted immediately shut their mouths. This was said out of the blue, so I didn't hear it clearly.

Yang's army is not playing by the rules.

At this time, Yang Xiaotao looked at the number on the screen, 64. Everyone also looked at the screen, very happy.

"It seems that everyone is good at arithmetic."

"Of course, the premise is that you can hear it clearly."

Yang Xiaotao joked, then cleared his throat again, "Listen carefully, what is sixty-four times sixty-four?"

After Yang Xiaotao asked the question, some people around him calculated in their minds, some gestured with their fingers, and some even took a pen and started calculating.

But Yang Xiaotao had already stopped at this time, and only the words '4096' appeared on the screen.

Wang Kun and Liu Yongqiang looked at each other and were both excited.

They have tried this kind of test before, and Yang Xiaotao's experiment this time was more "shocking" to everyone.

"Four thousand and ninety-six."

Someone shouted, and more people listened and nodded.

However, when they saw the display screen in front of Yang Xiaotao, the smiles on everyone's faces disappeared.

Because the numbers on it are the same as the results they calculated.

However, they took seven or eight seconds, while Yang's troops only took three seconds.

"That's right."

Yang Xiaotao asked softly and everyone nodded.

Many people looked at the calculator.

Yang Xiaotao's operation just now was very simple, especially for people like Lou Xiao'e who often deal with numbers. They were already thinking in their minds that if there was such a machine, their future work would be much easier.

"Go on, listen carefully."

"What is 4096 times 4096?"

After Yang Xiaotao asked this question, everyone's faces changed.

Many people scratched their heads because the multiplication of these four-digit numbers was beyond their calculation ability.

Some people saw Yang Xiaotao's intention and wanted to see if this machine could figure it out.

However, some people still took out paper and pen to calculate seriously.

Yang Xiaotao continued to press the buttons slowly and steadily, and every time he pressed the buttons, 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 and felt dazzled.

It’s so long.

At the same time, I was a little curious. It was calculated so quickly. Could it be so accurate?

At this time, someone finally figured out the result, and then took the paper and started reading, "16777216!"

Every time a number is read out, everyone will look at the display screen.

After the last sentence was read, everyone was silent for a moment, and then burst into applause.

Han Sanfeng suddenly realized that the biggest advantage of this calculator is its speed!
The more complex the arithmetic, the faster it can be solved.

If the results were more accurate, this calculator could greatly improve the efficiency of certain tasks.

As for accuracy?

Han Sanfeng also studies computers, and of course knows that as long as the computer is properly configured, it will perform better than humans.

Thinking of this, Han Sanfeng felt a little regretful.

I regret not starting research on computer integrated circuits sooner.

'Fortunately, it's not too late!'

I made up my mind that after today, the focus of the research center would shift.

No matter how well transistor computers are researched, they are just chasing on the lower track.

If you want to surpass your competitors, you have to think of some unconventional tricks.

On the other side, Yang Xiaotao nodded, and then recognized the person who was finally calculated. He was the first batch of students who entered the classroom of Yangjiazhuang Primary School.

Yang stick.

The child made a deep impression on him back then.

Because I was young, I couldn’t keep up with the pace at school.

When he was promoted from elementary school to junior high school, Yang Xiaotao and Ran Qiuye were still hesitant about whether to let him participate.

Later, I joined in, just to make some appearance and see the world.

Unexpectedly, this kid worked hard and actually passed the exam.

Although he was ranked last, he just barely passed the exam and was admitted to junior high school.

Later, Yang Xiaotao did not pay special attention to the development of these students, but he kept in touch with Ran Qiuye from time to time.

"Let's continue."

Yang Gun was stunned for a moment, then immediately said, "Okay, Teacher Yang."

No one cared about the name Yang Gun, as they all knew about what happened in Yangjiazhuang.

"What is 16777216 divided by 32?"

After hearing this, Yang Gun quickly took his notebook and pencil to the side and started calculating.

This time Yang Xiaotao didn't need to say anything. Han Sanfeng went to the calculator, started typing in some information, and then pressed the equal sign.

524288!

Han Sanfeng read out the number, and then everyone's eyes turned to the young man lying on the table not far away.

At this moment, Yang Gun's forehead was covered with sweat, especially when he heard the voice coming from behind and felt the attention, which made him feel like he was being watched.

At the same time, he didn't want to make a fool of himself in front of Teacher Yang because that would bring shame to Teacher Yang.

Division is more difficult than multiplication because it also requires multiplication and subtraction.

So, more than two minutes later, Yang Gun came up with a notebook and shouted out the calculated result.

After a moment, Yang Xiaotao clapped softly.

Then there was warm applause.

“That’s a good calculation.”

Yang Xiaotao smiled at Yang Gun, then took out the pen from his pocket and said, "This is a reward for you."

Yang Gun was stunned for a moment, then carefully took it at the urging of the people around him.

"I'm rewarding you not only because you calculated correctly, but also because you were willing to calculate."

“Many things in this world seem difficult, but when you really start doing them, you’ll find they’re not as difficult as you imagined.”

Although Yang Xiaotao said this to Yang Gun, everyone present kept it in mind.

Han Sanfeng, in particular, felt that this was Yang Xiaotao's wake-up call, and he made up his mind to form a team as soon as possible.

Next are Wang Kun and Liu Yongqiang, who are the ones who are most touched.

When Yang Xiaotao found them and explained the situation, they still found it a little 'unbelievable'.

But later, I persisted step by step until now.

Now, isn’t it a success?

"Actually, the hardest thing is to convince yourself to take the first step!"
