I control the AI ​​empire thanks to the geniuses in my group.

Su Zhou was stunned.

No, wait.

He glanced down at his draft paper; it was blank and spotless, not even the pen cap had been removed.

I glanced at the question on the blackboard again.

6983×596.

Did he just calculate that in his head?

Su Zhou rubbed his eyes, wondering if he was hallucinating.

He decided to verify it.

Let's move on to the second question.

20608 ÷ 23 = ?

There was almost no mental calculation involved; the answer just floated out like a barrage of comments.

896.

The third way.

7764+8839=16603.

The fourth one.

9153×847=7752591.

The fifth one.

……

Su Zhou read from the first question to the last, 50 addition, subtraction, multiplication, and division problems involving four- and five-digit numbers. Every time his eyes swept over a question, the answer would automatically appear in his mind, as fast as if he had a cheat code.

No, this isn't like having a cheat code.

That's like using a cheat code!

The numbers automatically formed the answer before his eyes!

Is the +15 instant mental arithmetic bonus he just received real?

If mental arithmetic skills are real, then those people in group number 42...

Qian Xuesen, Turing, von Neumann...

dare not think, dare not think.

Su Zhou calmed herself down.

Don't jump to conclusions just yet; what if it's just a coincidence?

Lin Xiaoxiao, who was engrossed in calculations, had already filled more than half a page of draft paper. Hearing no sound from the side, she glanced at him.

Then she saw a scene that made her question the meaning of life.

Su Zhou's draft paper was completely blank on the front.

"You..." Lin Xiaoxiao's mouth opened slightly, about to say something, but she swallowed it back.

It seems they don't know how to calculate.

Poor thing, I'll have to give him a little extra lessons later.

Lin Xiaoxiao thought about it very responsibly, then lowered her head and continued to struggle with her draft paper.

Five minutes later.

"Is everything ready?"

The voice of math teacher Liu Zhi came from the podium.

A few hands were raised sparsely in the classroom, while most people were still writing furiously.

There are no patterns to follow in addition, subtraction, multiplication, and division of four- and five-digit numbers; it's just brute force. Teacher Liu gave 15 minutes for 50 questions, not expecting everyone to finish them.

He began to walk around the classroom, checking each student's answers.

He walked up to Su Zhou's seat and stopped.

The student had his pen on the table, the front of his draft paper was blank, and he was staring out the window in a daze.

Teacher Liu frowned.

Sigh, students these days are really something; they can't handle even slightly difficult addition, subtraction, multiplication, and division calculations.

He bent down, lowered his voice, and tried to use a gentle tone: "Su Zhou, is it that you're having trouble with the questions?"

Su Zhou snapped out of her daze: "Huh?"

"It's okay," Teacher Liu patted his shoulder. "You've been on leave for a year, so it's normal for your foundation to be weak. You don't have to do these questions for now. Just listen carefully when I explain them later."

Several classmates nearby secretly cast glances at him; some were sympathetic, some were watching the spectacle, and some were indifferent.

Su Zhou honestly replied, "Teacher Liu, I'm done."

Teacher Liu's smile froze slightly.

He glanced subconsciously at the clean draft paper in front of Su Zhou, which was even cleaner than his face, and said, "Finished? Finished all 50 questions?"

"Um."

Teacher Liu straightened up, her voice unconsciously rising a little: "Su Zhou, these questions are all four- or five-digit calculations. I don't see you even picked up a pen; your scratch paper was blank. How did you do them?"

The classroom fell silent for a moment.

Several students who were engrossed in solving problems couldn't help but look up.

Su Zhou thought for a moment and said, "I did the mental calculation."

"Can you do mental arithmetic for a four-digit number multiplied by a three-digit number?"

"Um."

"Then tell me the answer."

After saying this, Teacher Liu himself felt it was a bit absurd.

Out of professional ethics as a teacher, he still took out a small notebook from his pocket, on which he wrote down the standard answer he had calculated with a calculator.

Yes, the standard answer was the one he typed out using a calculator before entering the classroom.

These problems were made up on the spot; the numbers had no pattern, and there were no shortcuts or tricks to solve them quickly.

For example, the formulas like "the first and last parts remain unchanged, and the sum of the middle parts is pulled down" are not applicable to these questions at all.

The only solution is to use brute force and calculate it directly.

"First question," Su Zhou looked at the blackboard and answered without hesitation, "6983 multiplied by 596 equals 4161868."

Teacher Liu glanced down at the notebook.

4161868.

correct.

It's probably a coincidence.

"Question 2, 896."

Teacher Liu took another look.

correct.

"Question 3, 16603."

correct.

"Question 4, 7752591."

Teacher Liu blinked.

correct.

"Question 5..."

"Wait a minute," Teacher Liu raised her hand to interrupt him, "Let's start with question 30."

"Question 30," Su Zhou glanced at the blackboard, "5986 multiplied by 473 equals 2831378."

Teacher Liu looked down and flipped through her notebook.

2831378.

Word for word.

"Question 42," Teacher Liu said, taking the initiative to call on the question.

"8821 minus 3957 multiplied by 64 equals 311296."

Teacher Liu paused for a moment as she flipped through the notebook.

This is a mixed problem involving two steps, a deliberately difficult problem he set.

The answer is 311296.

correct.

"What about the last question?"

"2065".

Teacher Liu closed the notebook.

He had never seen anyone in real life who could mentally calculate multiplication and division of four or five digits; at least, he couldn't do it yet.

Not to mention a first-year junior high school student.

"Su Zhou, have you received professional mental arithmetic training before? Abacus mental arithmetic?"

Su Zhou shook his head: "No."

"What kind of math thinking training courses have you attended? Math Olympiad?"

"No, not at all."

Teacher Liu fell silent.

He admitted that he had indeed underestimated the student.

The numbers for these questions were made up on the spot, and the answers were obtained by pressing a calculator; there was absolutely no prior leak.

Finally, Teacher Liu patted him on the shoulder and said, "Your calculation skills are good. Since we haven't chosen anyone yet for math class representative, why don't we make you?"

what?

I'm the class representative?

Su Zhou never wanted to do something so thankless.

Being a class representative always feels like being the teacher's lackey, and your prestige just drops!

But he couldn't persuade Teacher Liu right now, so he had to agree for the time being.

Ms. Liu turned to the class and continued, "Alright, hand in your answers now..."

Lin Xiaoxiao stared blankly at Su Zhou.

She originally thought Su Zhou was a loser, but she didn't expect that Su Zhou was actually quite capable and had solved all the questions in his head!

And the answer given was correct!

Mom!

I've met a real academic superstar!

If I master this skill, won't I be able to kill everything in sight from now on?

Her eyes lit up, and she clasped her hands together, whispering to Su Zhou, "Su Zhou, please teach me this move!"

Um, how do I teach this?

Su Zhou suddenly realized that there really is a gap between smart people and geniuses in the traditional sense!

Because only he himself knew the terrifying changes that had occurred in his brain just moments ago.

The moment that seemingly random string of numbers entered his eyes, he didn't need to do any traditional calculations. Instead, it was as if a program was generated in his mind that automatically substituted them into the calculations and quickly gave him the answer!

No wonder it is said that Qian Lao could do mental arithmetic when he was three years old.

Others see mountains as mountains and water as water.

In the eyes of a genius like Qian Xuesen, everything has probably long lost its superficial meaning. For them, the concept of calculation process simply doesn't exist.

Because the moment they see the question, their minds have already traversed thousands of miles and are directly at the end of the answer.

That's the barrier!

A barrier that no matter how much practice questions or how many all-nighters an ordinary person does, they can never overcome!

When Su Zhou heard legends about Qian Lao before, he always felt that they were just later people creating a god, with some exaggeration and flattery involved.

But now, as the extraordinary state truly unfolded in his own mind, he realized with horror and awe that the rumors were not exaggerated, but rather perhaps even less so.

Therefore, Mr. Qian's red envelope was genuine.

No one set a trap for him; Lin Xiaoxiao is innocent!

Su Zhou realized a key point.

When the instantaneous mental calculation value is ≥10, it is possible to mentally calculate multi-digit addition, subtraction, multiplication and division problems. Now his value is 23, so this skill is definitely not just as simple as calculating addition, subtraction, multiplication and division!

If people in the group keep sending him red envelopes, wouldn't he be able to achieve his goal of building artificial intelligence very quickly?

After finally getting through get out of class, Su Zhou opened his phone and found that Qian Lao and Leibniz had gone offline, while only Newton and a few others were still active in the group.
