Chapter 5: An attribute called 'workaholic'
After a few minutes of excitement, the same question came to mind.
"7812378*7812378=..."
???
??
Still can't do it in one second, what's going on?
As... cough, a genius, shouldn't be difficult to solve such problems!
Zhang Yuan furrowed his brows, and a multiplication pose appeared in his mind. He stumbled for half a minute before coming up with the final result.
"61033250014884."
Not bad, I still made it.
After careful consideration, a faint moment appeared on his face.
"I see... I realized that when I encountered this kind of problem, I solved it directly using the computer, resulting in a significant degradation of my computational skills. Even a genius cannot immediately answer it without thinking about it."
"The calculation is slow now, just because my proficiency is not enough and I haven't mastered the relevant skills. If I use mental arithmetic for a long time, I will definitely improve gradually."
The next day
Zhang Yuan woke up with drowsy eyes and rubbed his confused head.
Perhaps it was because I was too excited last night and kept testing my IQ, so I couldn't fall asleep for a long time. By the time I finally fell asleep, it was almost dawn.
At first glance, it's already 10 o'clock.
"Damn it!"
Zhang Yuan rolled up from the bed, quickly washed himself for a while, and then hurriedly walked out of the house.
"I hope not to be late, otherwise my aunt will be nagging for a long time..."
The 30 day holiday is very urgent, and there are clear arrangements for each day. I have already made an appointment today to go to my aunt's house for lunch.
In July, Donghua City was like a furnace, with a tumultuous heat wave, and the plants on the roadside were in deep water and heat.
Zhang Yuan hurried to the subway station, where there was always comfortable air conditioning.
In this era, there is no shortage of energy. The power generation of every large fusion nuclear power plant is comparable to the Three Gorges hydropower station in the past, and the price of domestic electricity is as low as 3 cents per degree.
Thanks to this, in addition to the high prices of petroleum derivatives such as plastics, high-energy industrial products such as steel and cement have become exceptionally cheap.
Especially with the booming development of nanotechnology, building materials are also being updated and replaced from generation to generation. For example, adding 6% of the cement content to nano silica can increase the compressive strength by two times and comprehensively improve the workability of concrete.
The popularization of cheap new materials has led to the increasing height of surface buildings in cities, with thousands of high-rise buildings everywhere.
Two hundred years ago, the 828-meter-high Dubai Tower was the tallest building in the world, but now it can only be considered the tallest building in the village.
And... at the same cost, at least five buildings can be built!
Some transportation tracks are even placed thousands of kilometers high, with skyscrapers as the pillars of the tracks.
Almost all big cities are very popular with these, and the air track has become the facade of big cities.
"There are many people."
Donghua City is one of the top five first tier cities in Xiaguo, and even though it has missed the morning rush hour, the subway station is still crowded with people.
"Ladies and gentlemen, please show respect to the elderly and children."
"Please do not smoke or beg in the carriage."
It is impossible to completely solve the traffic problem.
Spitters always find the most comfortable angle to criticize the government. If the transportation is too crowded, the government will definitely get sprayed; But if there are too many subways and a large number of empty seats, it will be considered a "waste of taxpayer money". Anyway, it will be sprayed no matter what, just make do with it.
Zhang Yuan lined up at the back of the queue and heard someone constantly complaining about "not increasing the number of trains" and so on. He smiled in his heart, but didn't have many ideas. Instead, he picked up his phone and started asking questions on his own.
This is a very popular "Super Brain" app that can test a person's memory, arithmetic ability, and reasoning ability. Anyway, being idle is also boring. It's also good to brush a few questions, and also to test one's intelligence.
Intelligence is currently his biggest concern.
Whenever I test my intelligence to be very high, I feel so happy that words cannot describe it.
The subway station is very noisy and difficult to concentrate, but I don't know what's going on. Doing questions always creates a wonderful sense of achievement, giving him a feeling of eating chocolate beans.
Perhaps after using that potion, there was an additional attribute called 'workaholic' on the body?
"I finally understand why some people are willing to work all day long. It turns out they are happy and don't want it. Using their brains has become a very fun thing!"
Dingdong
As the subway entered the station, the crowd surged in like a tide, and the area originally lined up was cleared.
Zhang Yuan walked into the subway, casually found a place to stand and asked questions one after another.
The four arithmetic operations of seven digits have changed from once every half minute to once every 10 seconds with increasing proficiency, and the speed of the operations is still increasing.
The feeling that the answer was about to come out slowly emerged.
The more he used his brain, the more agile it became, and this result satisfied his heart.
Soon, he began to be dissatisfied with ordinary arithmetic operations and instead switched to square root operations.
"Let's start with a simple one, √ 7812 (keep four significant digits)"
Zhang Yuan increased the difficulty for himself.
There are many different ways to manually square an integer. The most conventional method is called trial quotient, which is somewhat similar to division. As long as one has sufficient mental arithmetic ability, they can indeed calculate directly.
Some algorithms are slightly troublesome, such as continued fraction expansion, dichotomy, Newton iteration, etc.
Fifteen seconds later, he arrived at a specific conclusion.
"√7812=88.38..."
The answer is correct!
"√444"
"21.07"
The answer is correct!
ha-ha!
Is this the feeling of being a genius?
Really... fragrant!
The carriage was very quiet, except for the electronic prompt sound of the subway, everyone was busy immersing themselves in their own world.
Occasionally, a few guys, whether reading novels or watching videos, couldn't help but laugh when they saw the climax, just like idiots
"The fragmented time on the subway should be used to improve oneself, not for entertainment!"
A "public figure" who returned from studying abroad furrowed his brow and was lamenting this unhealthy social atmosphere.
The phenomenon of "bowing heads" is often criticized by major media outlets, but even if criticized, it is not very useful. Everyone should play and bow their heads. The government should not legislate to prohibit playing with mobile phones in public places, right?
This man's name is Ye Fan, and in his perception, in foreign subways, everyone is reading newspapers instead of playing with their phones, and the atmosphere is a hundred times better than Xia Guo (in fact, there is no internet).
Anyway, in his impression, young people from abroad live much healthier lives than young people from Xia!
"No wonder this group of people can't go into space, that's because they spend their learning time on entertainment... It's strange if they can go into space! "Ye Fan thought secretly.
"What's the saying? I just spend everyone else's coffee time at work."
Especially the young man wearing short sleeves around him had a sweet smile on his face.
Tut tut, you should be in love with a anime girl, right?
Not promising!
