Chapter 817 This is the Gap

With Shining and Lu Shi’an two college gods, that class, but for the problems they both struggled with, even Teacher Ding in the entire classroom was afraid to interrupt and talk casually. I was afraid that I would interrupt like this, so I inquired about the wonderful differences between the two of them. question.

  "Your idea is but the answer is definitely 14, 60. From the conditions..." Shi Ning stood on the podium, writing quickly on the blackboard with a chalk in hand, "And a1

  b10...repeated use of {am} recurrence relationship..."

This is a league question. It is very difficult. Shi Ning said and wrote on the same time. After a while, he filled the two blackboards, "...to get the only positive integer...To summarize, all possible a1+b1 are 14, 60, It is definitely not 13, 60, Lu Baoan, you are at this step..."

  Shining took a piece of chalk and swiped under the verification on the second blackboard, "Forget it here, there is no solution. If you don’t believe me, 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 in the river, running happily all the way, tirelessly, just feeling that you are flying, the harder you are, the more you want to conquer. Once the conquest is successful, you will gain The great sense of accomplishment will have a kind of joy of stepping on the clouds.

  Shining, I like this feeling very much, and also very fond of the duel with Lu Shian and Xi Qinghuan, and he is happily looking forward to the next duel.

  The students under the podium followed Shi Ning's thinking. Oh, shit, it seems that Shi Ning's thinking is also right, but Lu Shi'an's thinking is also right, and the answer is right.

  So who is right and who is wrong?

Teacher Ding glanced at the corners of his eyes and the corners of his mouth tightened slightly, and looked at Lu Shian, who was holding the newspaper. Then, when he looked at the smiling and confident Shi Ning, the smiling teacher Ding said, breaking the tense atmosphere in the classroom, "Xi Qing Huan, what about you, what is your answer."

  Xi Qinghuan glanced at his answer, Qing Lingling's peach blossom glanced at Shining, and said calmly: "13, 60."

  "Wrong, 14, 60." Shi Ning smiled, and chalked a stroke under the analysis process of the third report, "You must be a problem here."

  Xi Qinghuan didn't even read his answer book. When Teacher Ding and his classmates watched, he nodded slowly. That's right, he was Shi Ning who pointed out that this place is different from Shi Ning.

"The only positive number obtained here is a1=18, at this time a1+b1=20, not 60." Shi Ning's gaze looked at the silent Lu Shi'an for a moment, and the corners of his mouth raised slightly, "Student Lu, I Are you right?"

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

   Hearing the words, he smiled and said: "Well, I was wrong with this question. It is indeed 14,60. You won." This is the third time he has lost to Shi Ning.

  Shining put down the chalk, patted the dust, and smiled and said: "Next time, I will continue to beat you."

"Let’s wait and see." Lu Shian happily took the challenge. Shi Ning liked this kind of matchup between his opponents. Similarly, Lu Shian also liked it very much. The pleasure of being on top of the mountains and being a master would make you see farther and know better. There is a sky outside the world, and there are people outside the world, so you can make yourself more cautious and don't forget about it.

  The two of them stopped the move. The students below all had a sense of microseconds of successfully surviving the catastrophe together, and some students had "sorrowed" happening. They hadn't figured out their ideas yet, and Xueshen had already solved the problem.

  Gap, this is the gap!

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

  It seems that there is no activity, I want to have an activity...

  The update is over today, see you tomorrow.
