The problem could not be solved, and the audience seemed extremely restless offstage.

But compared to the audience, Fang Nian seemed much calmer, sitting in his position and fiddling with the computer in front of him for a long time without seeing him answer the question.

Seeing this, Duan Rui's face showed a long-lost confidence, and he looked at Fang Nian and said lightly.

"How is Mr. Fang? If you can't solve it, turn to the next question, and there will be a charity dinner later, so don't delay everyone's time. ”

“YES!”

However, at this moment, Fang Nian finally screamed as if he had completed the test question.

Everyone was stunned for a moment, and then overjoyed, they all thought that Fang Nian was excited and shouted because he had solved this question, and they all looked at him and waited for the answer.

However, what they didn't expect was ......

"Sister Duan, do you know? This spider card game is actually quite difficult if you want to complete the mode of 4 decks of cards. Not only do you have to keep your cards, but you also have to have some luck to clear the level, which is really fun. ”

Duan Rui was stunned, and the audience below was also stunned, could it be that this thing had been playing spider solitaire just now? What about the solution?

Duan Rui really couldn't stand Fang Nian's contempt, and finally couldn't hold it anymore, and said angrily.

"Are you better than you? If you don't compare, you will kneel on the ground and call grandma, this sister will not have time to play with you here. ”

Fang Nian's smile suddenly froze, and he slapped his head, making a sudden realization.

"Oh, look at me, I'm sorry I forgot about it."

With that, Fang Nian tapped on the keyboard, and suddenly a formula appeared under Duan Rui's title.

“×”

"Actually, I have already solved this, but I am so engrossed in playing Spider Solitaire that I forgot to type out the answer, I'm really sorry."

Duan Rui looked at the answer in front of him, and his nose was really crooked. When has she ever been ridiculed like this when she is so old, and she is still in the field she is best at, which is a great shame for her. From Dao to Da, when did she suffer from this kind of wretched qi?

"You ......"

Although Duan Rui was angry, she really couldn't find any fault, the standard answer to this question was here, exactly the same as Fang Nian's answer, she really had nothing to say, people did have the capital to load pens.

Fang Nian looked at Duan Rui, who was blushing with anger, and said lightly.

"Actually, Sister Duan, you are really smart, I think when the purpose of this question is, Sister Duan just wants to lead me into your misunderstanding. Presumably, when many people see this problem, their first reaction is the idea that this is a calculation problem, and I'm right, right? ”

The audience nodded when they heard this, it is true that no matter who thinks so, this is such a question.

Fang Nian smiled and continued.

This is where Sister Duan is clever, in fact, what she came up with is not a calculation problem, but a reasoning problem that looks like a calculation problem. If we want to solve this problem, we don't need complex calculations, as long as we think logically, it can be easily solved, Sister Duan, I'm right, right? ”

Listening to Fang Nian's words, many people suddenly realized that they had been fooled with laughter.

But Duan Rui's face was already very ugly, she really didn't understand why there was such a shameless person as Fang Nian in the world.

"Don't talk nonsense, let's solve the second question."

Duan Rui tapped on the keyboard, and the second question appeared on the three-dimensional projection.

A tricycle and a cart of goods appear on the screen, as well as a delivery person.

Duan Rui pointed to the fist on the projection.

"As you can see, this is a tricycle full of goods, and the delivery man needs to deliver the goods to the customer's home 50 kilometers away from the company, because the company is in the mountains, and the mountain roads are also rugged and difficult, so as long as they drive 20 kilometers, the wheels will be scrapped."

At this point, Duan Rui changed his words and continued.

But what made it difficult for the delivery man was that he only had 5 spare tires, which means he only had 8 tires. So how can he safely deliver the goods to the customer's home? ”

After Duan Rui's question came out, everyone began to think about it again, but this time before they could finish analyzing the question, Fang Nian stood up and said lightly.

"Sister Duan, are you at this level?"

Duan Rui was stunned for a moment, and before he could speak, Fang Nian typed out all the answers, which were a string of spliced numbers.

“、、。”

"This question is obviously playing the logical trap of your hand, according to what you described, the tires need to be replaced every 20 kilometers, so 8 tires can't support 3 punctures, so logically this is an unsolvable problem."

"But if we change the tires every kilometer, all the tires can be used four times. We numbered a total of 8 tires, and we kept changing them according to the above numbers on the way. ”

"This allows us to maximize the wear and tear of each tire, so we can easily deliver the goods to the customer's home 50 kilometers away, and even have a surplus."

Fang Nian's explanation is very detailed, and it can also go straight to the core of the problem, and soon everyone understands, and some people even scold Fang Nian behind their backs, this problem is solved so quickly, they have no sense of existence, and they can't even find the fun of solving the problem.

Duan Rui had completely lost his patience, and he didn't even take out his last hole card directly, and the third question appeared.

A three-dimensional heptagon appears on the three-dimensional projection, with a circle at each corner and on each side of the heptagon, adding up to 14 in total. At the same time, there are 14 numbers arranged under the heptagon, which are 1~14.

"This is a combination lock, you need to fill in the numbers of 1~14 into these circles, and finally you need to add up the 3 numbers on each side to be 26, please answer."

Fang Nian frowned slightly as he looked at the topic in front of him, and his face became a little ugly, obviously this time he was not as calm as he was solving the first two questions.

The change in Fang Nian's expression was all in Duan Rui's eyes, and for a while, the corners of his mouth hooked up a long-lost smile.

"It seems that I am right, you are just studying logical thinking. Now that I've replaced the decryption idea of the combination lock with digital thinking, you can't unlock it. ”

Everyone was a little stunned by Duan Rui's words, but when it came to Fang Nian's heart, Fang Nian's heart really wanted to cry at this time, this girl was indeed not ordinary.

Duan Rui is very right, almost all of the questions she came up with before were solved by logical thinking. Fang Nian has been blessed by logical thinking, and to solve these problems is naturally twice the result with half the effort.

I thought that the last question would still use logical thinking to make propositions. didn't expect her to find out about this and change her routine. Nowadays, this problem is obviously a proposition of numerical thinking, and although the mathematical concept is also well learned, it is still far from being indistinguishable from the ghost.

Thinking of this, Fang Nian couldn't help but sigh in his heart.

"The current situation is really not easy to solve."
