With Shi Ning and Lu Zhi'an, the two university gods, that class, but whenever the two of them are fighting for a difficult problem, even Teacher Ding in the whole classroom does not dare to interject casually, for fear that he will interject like this, so he will inquire about the wonderful debate between the two of them.

"If you think about it, the answer is definitely 14, 60. , from the conditions...... "Shi Ning stood on the podium, holding chalk and writing quickly on the blackboard," and a1

b10…… Repeated use of the recursive relation of {am} to know ......"

This is a league question, which is very difficult, Shi Ning wrote while talking, and after a while, he filled the two blackboards, "...... Get a unique positive integer...... To sum up, all the possibilities of A1+B1 are 14,60, and it is absolutely impossible to be 13,60, Lu Bao'an, you are ...... at this step"

Shi Ning took the chalk and swiped it under the verification on the second blackboard, "You can forget it here, there is no solution here." If you don't believe it, you can do the math yourself. ”

The greatest joy of mathematics lies in "verification", in the process of verification, it is like a fish swimming into a river, galloping happily all the way, tirelessly, only feeling that they are soaring, the more difficult it is, the more they want to conquer, once the conquest is successful, the great sense of achievement obtained will have a kind of foot on the clouds, fluttering joy.

Shi Ning likes this feeling very much, and also likes the duel with Lu Shi'an and Xi Qinghuan very much, and is so happy that he is looking forward to the next duel.

The students under the podium followed Shi Ning's train of thought, oh, it seems that Shi Ning's train of thought is also right, but Lu Zhi'an's train of thought is also right, and the answer is also right.

So who is right and who is wrong?

Teacher Ding glanced at Lu Zhi'an, whose corners of his mouth were slightly tightened, and his eyes were locked on the board, and then at Shi Ning, who was smiling at the corners of his mouth and full of confidence, and Teacher Ding, who had a smile in his eyes, opened his mouth and broke the tense atmosphere in the classroom, "Xi Qinghuan, what about you, what is your answer." ”

Xi Qinghuan glanced at his answer, Qing Lingling's peach blossom eyes glanced at Shi Ning, and said lightly: "13, 60." ”

"False, 14, 60." Shi Ning smiled, and the chalk drew a stroke under the analysis process of the third report black, "You must have something wrong here." ”

Xi Qinghuan didn't even look at his answer book, and when Teacher Ding and his classmates looked at him, he nodded slowly, that's right, he was the difference between Shi Ning and Shi Ning pointed out here.

"The only positive number obtained here is a1 = 18, in this case a1 + b1 = 20, not 60." Shi Ning's gaze looked at the silent Lu Zhi'an for a moment, and the corners of his mouth were slightly hooked, "Classmate Lu, am I right?" ”

Lu Zhi'an had already read Shi Ning's entire analysis, and he quickly analyzed it in his heart, and when Shi Ning asked him, it was the time when he calculated the answer in his heart.

Hearing this, he smiled and said, "Well, I was wrong about this question, it is indeed 14, 60, you won." This is the third time he has been defeated at the hands of Shi Ning.

Shi Ning put the chalk down, patted the dust, and said with a smile: "Next time, continue to win you." ”

"We'll see." Lu Zhi'an happily responded to the battle, Shi Ning likes this kind of chess matchup against the opponent, and similarly, Lu Zhi'an also likes it very much, the kind of pleasure of competing with the master on the top of the mountains will make you see farther, and you can know that there is a sky outside the sky, and there are people outside the people, so you can make yourself more cautious, and you must not get carried away.

The two of them stopped moving, and the students below all had a sense of microseconds of successfully crossing the catastrophe together, and some students had "sadness" happening, and they hadn't figured out their thoughts yet, and Xueshen had already solved the problem thoroughly.

The gap, that's the gap!

And the Academy of Sciences received a postal package from Southern Province, which was a package for Le Lao, and it looked like a document in his hand.
