It sounded disorganized and seemed like there was no way to start, but Sugar Treasure quickly stopped his irritability and started thinking again.

Soon, she remembered the drawer principle she had seen in other books before.

Considering the most unfavorable situation, the first one can be tried a maximum of 9 times, the second one can be tried a maximum of 8 times, and so on, and the maximum number of attempts that need to be made is: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45 times!

So the answer is 45 times!

Writing down the answer, Tangbao raised his head and faced the master, the master nodded with satisfaction, motioned for her to continue to do the other questions below, and walked behind Bi Jiujun.

I saw Bi Jiujun scratching his ears and cheeks, drawing a lot of pictures, and then he thought of the drawer principle and made it, but in the end, he miscalculated the arithmetic addition.

The mistake is in the last step of the simplest.

The master shook his head and slapped Bi Jiujun on the head, "It's okay if you do the slowest in the audience, you have a poor foundation, I can understand it." You have done everything wrong for me, Bi Jiujun, go back and practice for me! ”

He and his grandmother have a Ph.D. in mathematics from Huaqing and a master's degree from Harvard Polytechnic...... So infuriating?!

Bi Jiujun was accustomed to it, dodging the beating, and by the way, he looked at the progress of others and tried to catch up.

Seeing that he has a good attitude, Bi Lao won't say much.

This busy is a whole day, except for the forty minutes of eating and an hour of lunch break, the rest of the time is studying, and at six o'clock in the afternoon, the master took Bi Jiujun's ears and left.

After dinner, because I was too busy and tired in the past few days, I didn't continue to practice, but chose to rest, and the next morning, Professor Li of Chinese painting came.

The basic introduction starts with tasting and painting flower petals, and I only did this all day, and Sugar Treasure feels that this is much more tiring than math.

But the teacher praised her for drawing the best, hehe, the fatigue is halved!

The weekend passed like this, and next Saturday's tutoring was Grandpa Xiong's physics, and Sugar Treasure still felt very much looking forward to it, and after being busy, he began to review mathematics after washing up.

It didn't stop until ten o'clock in the evening.

As soon as he lay on the bed, he was about to close his eyes and start practicing mind reading and beast control, when the little genius's phone and watch rang, and Sugar Bao pressed it to connect, and his voice was lazy.

"Hey, Sisi, why haven't you slept yet? It's school tomorrow! ”

"Sugar Baby! Sugar Baby! Sugar baby! I'm so happy, I can't sleep, I'm going to tell you a very good news, I just knew, so suddenly I couldn't sleep happily, I can only talk to you! ”

Tian Sisi on the opposite side was extremely excited, and she seemed to be jumping on the bed when she heard the sound!

Sugar Bao snorted and regained a little spirit, "What news do you say, it's worth being so happy!! ”

I guess I won't win the lottery!

Tian Sisi has been talking before, if she is lucky, she will buy a lottery ticket, win her 5 million, and walk to the peak of her life!

"Hahaha, Sugar Baby, speaking of which, I would like to thank you and your father! By the way, and your second sister, I don't know what your second sister said to my dad, my dad was completely enlightened, in my mother's words, he finally got rid of that vampire! ”

The more Tian Sisi spoke, the more excited she became, and her tone was full of yearning for the future.

"Then I got him a new company and went to work tomorrow! I heard that there are more than 1 million a year, so wouldn't it be possible to buy a house in three years, my parents have just discussed, my father's salary has been saved up to buy a house in the past three years, and my mother's is used as the living expenses of the whole family!! ”

As she spoke, Tian Sisi began to exclaim.

"Since Sugar Treasure met you, our family's luck has become good! Thank you so much! ”

"What's so thankful for this, they are all friends, and your family's luck has become better, it must be because of your own family's good character, go to bed early!"

Sugar Bao has never seen such a lively and happy Tian Sisi, she was stunned to accompany her to sleep when she was excited and tired before hanging up the phone, although she was very tired, but she couldn't stop practicing.

After practicing secretly for half an hour, Sugar Baby closed his eyes and fell asleep.

Early the next morning, I didn't wake up naturally for the first time, but was woken up by Grandma Liu in a daze, dressed and washed, and only relieved myself after breakfast.

The grandparents looked distressed, and they stopped talking, and Sugar Baby immediately trotted away to go to school.

After staying for a long time, they will definitely reduce their study time because they are worried about themselves.

Tian Sisi is not so happy every day, so the situation like yesterday will not happen every day, and it is not a big problem.

When she arrived at the school gate, Xiaofang no longer started barking, but hugged her thighs with her front legs to eat, and Tangbao had no choice but to buy rice balls to feed the dogs.

Tian Sisi jumped up and down from school, hugged her for a long time, coquettish, like a koala, followed Sugar Treasure to the classroom without letting go.

Everyone else came to grab the position, and they couldn't stop laughing when they heard Tian Sisi say the reason.

Li Mengmeng, "There is really some truth in what you say, I also arrived at this kindergarten, and my family's luck began to improve!" Since everyone's luck is so good, then it will be a good luck family in the future! ”

Zhang Lili applauded, chewed the last bite of plum vegetable cake in her mouth, "Okay, good, class by class, like a family, every day after school, go home together!" ”

"I think it's okay, now our family is good friends, we are also good friends, when we grow up, maybe the son will inherit the father's business, the daughter will inherit the mother's business, and then we will also work for Tangbao hahaha!"

Li Tao began to reason, and Tian Sisi nodded solemnly.

"What's wrong with that, Sugar Baby must be good to us!"

……

Although it was all a joke, invisibly, everyone seemed to have set their own goals!

After adapting to the last semester, everyone has become more cautious and hardworking in this semester's study and life, and the students have also taken the initiative to ask their parents to make up the class for themselves after class.

The learning atmosphere is getting higher and higher!

All the parents were amazed that they hadn't slept well for a long time.

Children become the most fond of learning at the age when they love to play the most, how terrifying!

As parents, they don't dare to slack off, children work so hard, they have to work hard, so they roll every day, roll every day, and are full of fighting energy.

Everyone thought that the students would not last for a few days, but who knew that this persistence would be a semester, and it was not until the final exams were over that everyone stopped for a few days off.

And the results of the class came out on the night of the holiday.

Except for Sugar Treasure and Gu Zhun with full marks in the class, almost everyone else has full marks, and there is only one or two points behind one or two subjects, and the results are amazing!

Everyone is very happy, especially Li Mengmeng's family, I knew that Li Mengmeng was the bottom middle school student at the beginning, and the three members of the Li family just came home after celebrating, and they met a Mediterranean man with glasses at the gate, and the other party smiled weirdly.

"Hello, I'm here to dig the wall...... No, I heard that Mr. Li's daughter did well in the final exam, so I came to congratulate her. ”
