Not only Curly Hair, but the other French students were also stunned at the moment, they never thought that a person's mental arithmetic speed could be so fast, if it was placed in their country, it would definitely cause a sensation!

The reason is very simple, because Western countries do not have ninety-nine multiplication tables at all, even college students, mental arithmetic skills are very poor, like Liu Fang's exaggerated performance, they have never seen it. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Liu Fang saw that the other party was in a daze, and said with a smile: "Why don't you come up with the question?" ”

Curly Mao reacted at this time, and he continued to ask the question, but every time Liu Fang could give an answer in an instant.

A French student with a calculator to verify the results is surrounded by others, and the gang exclaims every time the results are calculated.

When it came to the tenth question, Curly couldn't hold it anymore, and he stared at Liu Fang with a shocked expression, "You...... Who are you? ”

Liu Fang said lightly: "As I said before, I am the director of the International Department, and I will be responsible for managing you exchange students in the future." ”

Liu Fang said this, and the words changed: "You still can't come up with the question?" If you don't ask questions, throw in the towel. ”

Where will Curly Hair give in easily? He thought for a moment and said, "I really underestimated you before, but now I want to increase the difficulty of the question, do you have any opinions?" ”

Liu Fang smiled slightly: "It doesn't matter, as long as it's a math question, you can come up with whatever you want." ”

When Curly Hair heard this, he immediately regained his confidence, and he thought to himself: Multiplication and division are not difficult for you, and I don't believe that function problems are not difficult! If you can even do function problems, then I'll do high math problems!

Function problems involve calculus, in Curly's view, this is already very difficult, the so-called high math problems, in fact, are advanced mathematics problems, which is more difficult in Curly's view.

Thinking of this, he said, "Okay, listen, the first question is ......."

After Curly Mao came up with the problem, he thought that he could stump Liu Fang, but the result made him dumbfounded! As soon as his words fell, Liu Fang gave the answer!

"This ...... This ......"

Curly's eyes widened, and he had the expression of seeing a ghost. The others were similar to him, and they were all on the spot.

After a while, Curly opened his backpack and took out a notebook from it, and after verification, he found that the answer given by Liu Fang was completely correct! He slid his Adam's apple and said uncertainly, "Y-Have you seen this question before?" ”

Liu Fang smiled slightly: "I haven't seen the same topic, I have only seen a similar topic." ”

Curly Hairy Heart said: This guy's mental arithmetic level is really amazing! I can even calculate calculus! Damn, I can't have met a child prodigy, right?

In order to confirm his thoughts, Curly immediately came up with a second question, but there was still no suspense, and Liu Fang once again gave the answer in an instant. Through the comparison of curly hair, the results showed that Liu Fang's answer was completely correct.

Liu Anxin wondered: The two function problems produced by this guy are not much different from the high school math problems in China, is this the math level of French college students?

Liu Fang thought of this and said, "May I ask how big you are this year?" ”

Curly replied, "We are both sophomores in college. ”

Liu Fang was slightly stunned, and was even more surprised in his heart: Are French university sophomores only comparable to domestic high school students? It's not a joke, is it?

In order to confirm his guess, he spoke: "You just came up with so many questions, now it's my turn, right?" ”

Curly couldn't help but be shocked when he heard this, and said in his heart: This young man seems to be very powerful, his question should be very difficult, I am a few years older than him, if I can't answer, it will be so embarrassing.

"What the hell is your opinion?"

"Oh...... You can ask the question, and we will try to answer it. ”

Curly Mao's confidence in speaking is not so sufficient, Liu Fang is not nonsense, and directly came up with a math problem in the third year of domestic high school.

This question can only be regarded as moderately difficult at best, but what Liu Fang didn't expect was that the French college students present all frowned after hearing it, showing a thoughtful expression.

After a while, someone said weakly, "This ...... I wonder if we can calculate it in writing? ”

Liu Fang nodded generously: "No problem, you can all do written calculations, as long as one person answers correctly, you will pass this question." ”

As soon as Liu Fang's words fell, all the people present took out paper and pencils, lay down in front of the table and calculated, and everyone would exchange opinions from time to time.

After about five minutes, Curly was the only one who calculated the results, and after everyone's collective discussion, it was finally determined that Curly's answer was correct.

Liu Fang, who witnessed the whole process, was a little dumbfounded, and he thought to himself: This level of math problem, you actually spent so much effort to calculate it, this is too exaggerated, right? If I let the students in the third year of high school who are not too bad in mathematics in China do it, I am afraid that the answer will be obtained long ago.

Curly handed the answer to Liu Fang: "You can check it." ”

Liu Fang glanced at it slightly, then nodded: "Well, the answer is correct, I'll ask the second question." ”

This time, Liu released an algebra problem in the first year of high school, which is still very difficult at the level of the first year of high school, but in the second year of high school, it is very simple.

Just like last time, the group of French students still got together to discuss, and in the end, five people calculated the results, and one of them answered the wrong answer.

At this time, Liu Fang was completely dumbfounded, and he thought to himself: My good boy, these people are sophomores in college! Is it kidding me to do a first-year high school algebra problem and only four out of twelve people succeed?

Liu Fang couldn't bear it anymore when he thought of this, "Everyone, did any of you bring a math textbook?" Can you lend me a look? ”

This request was not excessive, and soon someone handed Liu Fang his math textbook.

Liu Fang quickly flipped through it, and the more he looked at him, the more strange his expression became, and after watching it for less than a minute, he couldn't help laughing.

Everyone present showed puzzled expressions, and Director Yu first asked, "Director Liu, what are you laughing at?" ”

Liu Fang almost didn't laugh: "What am I laughing at?" What's this...... Director Yu, don't you know that the math level of these exchange students is about the same as that of high school students in our country! Specifically, it's about the same level as the first half of the sophomore year of high school, and I thought they were so good! Hahahaha! ”

Director Yu showed a sluggish expression: "What? This...... Is this true? ”

Liu Fang clutched his stomach and handed the math textbook to Director Yu: "This is their sophomore math textbook, Director Yu, you will know if I am lying after reading it." ”
