Datang New Giants

Chapter 9 New Agreement
"Xiao Langjun, you've finished eating, you can talk now." Zheng Yanzhi said with a smile on her face.

With a smile on her pretty face, she had already hidden two pink fists in her sleeves, and she was still trembling slightly, Zheng Yanzhi felt that she hadn't been angry for more than half a year, not as much as this day.

Lu Ting burped, knowing that the arrogant little girl in front of him was on the verge of breaking out, so he stopped teasing her, and asked while drinking tea, "I just took two exams, I don't know which one Miss Xiaozhi wants to ask?" ?”

"Pheasant and rabbit in the same cage." Zheng Yanzhi had already thought about it, and this was a question that had troubled her for the longest time, so she said it without hesitation.

"There are many solutions to this problem. I wonder how many solutions Miss Xiaozhi used?"

What?many kinds of?There are many solutions to this problem?

Zheng Yanzhi was stunned on the spot, looked at Lu Ting's face, felt that he didn't look like a liar, and quickly asked: "Many kinds? How many kinds? The little girl only knows three kinds."

Professor Ming Suan, who wrote the question, mentioned that it took him a whole day to find three solutions. Lu Ting listened to the question for the first time, and he opened his mouth and said that there were many kinds. I once doubted my ability to calculate clearly.

"Not many, just ten. If you calm down, it's not impossible to think about one or two more." Lu Ting said with a frown.

The problem of chickens and rabbits in the same cage was shown on TV in later generations. Two kinds of math teachers competed and took turns to solve the problem. Each method was different. In the end, there were thirteen methods listed. There were too many and Lu Ting didn’t remember them all. Now Just remember ten relatively simple and interesting methods.

"Ten and ten?" Zheng Yanzhi's eyes were as big as a bull's eye, and she couldn't speak fluently.

I scratched my scalp to come up with three. Professor Ming Suan who wrote the question said he had four solutions. Lu Ting opened his mouth and said ten. He also said that he could come up with more when he calmed down. fetal?

If it weren't for Lu Ting's amazing performance, Zheng Yanzhi would have laughed at him on the spot, hesitated for a while, and quickly said anxiously: "Little Lang, can you teach me."

When she thought of such a difficult question, there were actually ten different solutions. Zheng Yanzhi, who was obsessed with calculations, couldn't hold back, and she didn't care about her bad impression on Lu Ting, so she hurriedly asked for advice.

Seeing that Lu Ting seemed unmoved, he quickly said: "Your Majesty, please don't worry, I will definitely speak well for you in front of my master, and the account will be recorded tomorrow, and the treatment is the same as that of my predecessor."

Lu Ting shook his head and said: "Miss Xiaozhi's words seem to require your attention to get the job. I rely on my own ability. Even if Miss Xiaozhi doesn't say anything, I believe my boss will see it. I will teach you like this, too. loss."

"My family. You can worship the young master as your teacher, and Shu Xiu will definitely be there." Zheng Yanzhi was not afraid that Lu Ting would lie to her.

If he dares to lie, he will definitely not let him have a good time.

"Forget it" Lu Ting waved his hand and said, "You are just a little maid, so you don't have to wait on the master? You are not afraid of me, but you are afraid that the master will scold me for being troublesome. Besides, recruiting apprentices is too troublesome. If you encounter lazy troubles, and stupid troubles, I will take care of you." I can't be bothered to teach."

Hugging thick legs and finding a backer is the real thing. Lu Ting has no interest in being a good teacher, let alone worrying about it, what's the use of that little training.

"Who said that, my family." Zheng Yanzhi couldn't continue after only half of the sentence. She was a lady of the Zheng family in Xingyang. If the news about her serving tea and snacks to strange men got out, she wouldn't let the little sisters die of laughter.

"Say it, why don't you say it." Lu Ting said with a smile on his face.

Proud of the villain, Zheng Yanzhi clenched her fist, rolled her eyes, and quickly said with a calm face: "You have done a good job. My family will suggest that the master let you complete the three-month novice period, and give all positions to you. Do it all again, so that you can become more familiar with the operation of Kelaiju, and then consider becoming a regular based on performance in three months."

"You..." Lu Ting's expression froze, and he quickly said with a serious face: "Didn't Miss Xiaozhi agree to be exempted from the novice period, and her service is the same as her predecessor's accounting, so it's not good to change her mind so quickly."

Lu Ting didn't doubt her words, Lin Zheng attached great importance to this maidservant, if there were other people, she would turn around and leave by herself, but the owner, Lin Zheng, was from the Xingyang Zheng family, maybe she would need her recommendation in the future, this was also her performance One of the reasons is that it is a bit of a waste of time to do a bookkeeping. If you are a handyman who feeds Yexiang and feeds horses for three months, you will kill yourself.

"Didn't the ancients say that only women and villains are difficult to raise?" Zheng Yanzhi saw Lu Ting's expression of wanting to be angry but not daring to be angry, she was in a good mood, as if most of the anger she had suffered just now had dissipated.

Lu Ting took a deep breath, calmed down, put on a smiling face, and said softly: "Just now I was just joking with Miss Xiaozhi, what I mean is that you don't need to ask a teacher, you can also teach you how to solve problems, how about it, I will teach you a way to solve problems every day, and in return, Shu Xiu will forget it, just bring me some snacks."

A little maid probably doesn't have much money, and she doesn't just come here for money. If Lin Zhengshi knows that she is a person who cheats the little maid of money, all her efforts will be in vain. Now she has no money. He didn't have any monthly silver when he just joined the job, and the little school rice in the clan wouldn't last long, so he just asked this little maid to bring him some delicious food.

Those kinds of solutions are useless to me, so I might as well use them to get some benefits.

"Okay, it's a deal." Seeing Lu Ting softened, Zheng Yanzhi smiled and agreed on the spot.

As long as you promise to teach yourself the knowledge of clear calculation, everything is easy to talk about, don’t you just eat, just give me an order, I wanted to ridicule Lu Ting, but I swallowed the words back, I was so offended, I’m afraid that this talented person The prodigal son didn't pay attention when teaching himself, so don't worry about it, first learn his problem-solving skills, and then deal with him according to his mood.

Before Lu Ting could speak, Zheng Yanzhi immediately added: "Start now."

Seeing Zheng Yanzhi's serious expression, Lu Ting knew that if he didn't explain, this arrogant little maid would definitely not let him sit at the table. Anyway, explaining is easy, so he nodded: "Miss Xiaozhi, what do you say? There are three ways to solve this problem, but which three should be used?"

I still remember ten kinds of solutions, and I don’t know if there are any solutions that include her, so ask clearly first, and talk about one solution that she doesn’t use every day, so that I can spend a few days eating delicious food.

Zheng Yanzhi didn't refuse, and simply introduced her approach. She just wanted to say that if Lu Ting didn't understand, she could explain it in more detail, but she didn't expect Lu Ting to say immediately after listening, "I guess it's about the same. Table method, drawing method and cutting foot method, um, not bad."

The table drawing method is equivalent to the method of elimination. The chicken and the rabbit have only 69 heads. First, assume that the chicken has 68 and the rabbit has [-] heads. Check if the foot symbols do not match. Only, verify that the number of feet is the same, and use this method to enumerate until the numbers match;

The method of drawing is similar to that of drawing tables, except that seventy heads are cut out first, and these heads are not divided into chickens and rabbits, and then 180 eight legs are cut out, and these legs are glued under the heads, and the first round is to stick two pieces under each head. One leg, stick the remaining legs under the head in groups of two, you can count the legs after sticking, the one with two legs is a chicken, and the one with four legs is a rabbit, it's very simple;
The method of cutting off the feet is not difficult. If you cut off one foot of each chicken and two feet of each rabbit, then each chicken will become a "one-horned chicken" and each rabbit will become a "two-horned chicken". For rabbits with feet, half of the total number of feet appearing on the ground, the number of heads of chickens is counted once, and the number of heads of rabbits is equivalent to counted twice, so that the number of rabbits can be calculated.

not bad?It sounded like praise, but it sounded weird. This Lu Ting looked like he was not much older than him, and he spoke like a professor in the Gong Yuan. Zheng Yanzhi was a little upset when he transformed from a talented genius into his disciple, but she also felt uncomfortable. Did not say it.

"I also ask Mr. Xiao Lang for advice." In order to learn a new solution, Zheng Yanzhi endured it.

A flash of inspiration flashed in Lu Ting's mind, he laughed and coughed dryly, and then began to explain: "Today's method is the flute method."

In fact, it was the blowing whistle method. Lu Ting deliberately teased her and temporarily changed it to the blowing Xiao method.

Zheng Yanzhi frowned when she heard blowing flute. It was the first time she heard the saying of blowing flute. She wondered what it had to do with blowing flute. However, Lu Ting didn't seem to be joking, and she didn't say anything when she had doubts. , just concentrating on holding his breath, and straining his ears high, for fear that he might miss a word.

"Can Xiaozhi know how to blow a cockpit?"

"I haven't learned this instrument before. Is it related to problem solving?"

"It doesn't matter, but it has something to do with your life. Well, if a girl can play the flute, life will be much more exciting." Lu Ting deliberately stretched the pronunciation of the flute.

Zheng Yanzhi hesitated for a while, and finally nodded and said: "If there is a chance, I must learn from it."

Playing tricks on the tsundere little maid, Lu Ting was in such a good mood, he had a sense of satisfaction that his IQ crushed her, and he wanted to take advantage of her tongue, but seeing her serious face, he felt a little guilty Sensation, coughed dryly, and began to explain: "Suppose the pheasant and the rabbit have been trained to lift one leg when they blow the flute once, and when they blow the flute twice, both the pheasant and the rabbit will lift two legs. Miss Xiaozhi, if the pheasant lifts two legs , What will happen to it?" Lu Ting didn't finish speaking all at once, but deliberately paused to bring Zheng Yanzhi in.

"A chicken has only two legs. If you lift them up, you have to fall to the ground."

With a snap, Lu Ting snapped his fingers and said happily, "By the way, the chickens all fell to the ground, and the rabbits have four legs, and they are still standing. Don't worry about how many heads are still standing. The legs are half down. right?"

".right."

"That is to say, for seventy heads, two legs must fall from each head, that is, 140 legs, then the remaining legs"

Zheng Yanzhi, who had doubts at first, had a bright light in her eyes, a feeling of enlightenment in her heart, and said excitedly: "The rest of the legs belong to the rabbit, 180 minus 140 equals 48, and the two legs raised in front also That is to say, each of the remaining two legs represents a rabbit, a total of 24 rabbits, oh my God, how can I not think of it.”

This obvious problem can be solved in this way, why can't I think of it?Zheng Yanzhi looked at Lu Ting again with a different look.

Unexpectedly, the prodigal son is not only good-looking, but also so powerful that he really underestimated him.

The tsundere little maid didn't roll her eyes anymore, she looked at her differently, Lu Ting chuckled: "Miss Xiaozhi, if there is anything you don't understand, feel free to ask."

"Xie Xiaolang-jun for clarifying the confusion. This blowing method is simple and interesting. Xiaolang-jun explained it very thoroughly. I have no doubts." After a pause, Zheng Yanzhi said with some embarrassment: "It's too early to leave the banquet. I wonder if Xiaolang-jun can do it." Can't you teach the second solution?"

Ten solutions, I'm really excited to think about it, if it wasn't for the crime of murder, Zheng Yanzhi would have wanted someone to open Lu Ting's head to see what was inside.

"You can't chew too much. It's good to learn one in a day." Lu Ting said carelessly: "By the way, that sweet-scented osmanthus cake tastes good, bring a few more pieces tomorrow."

They all lowered their figure, this prodigal son actually refused, Zheng Yanzhi gritted her silver teeth angrily, but she couldn't get angry, she couldn't understand Lu Ting's sullen look, she stomped her feet and turned around, before leaving, she threw Give Lu Ting a beautiful look.

She has a big air, but she has a good mouth. The sweet-scented osmanthus cake was made by myself to honor my aunt. Just now, I went to the back kitchen to get some snacks. They happened to be gone, so I rewarded him with a few dollars. I didn’t expect him to be happy after eating it. I appointed tomorrow If you want to eat, hum, it's cheaper for him.
