Chapter 059, Cartesian Coordinate Systems and Unary Linear Equations

Thrilling escaped, Zhao Yan Ge mentioned how happy he was in his heart, he had just seen Lin Xian'er without clothes, his arrogant figure and charming face made him feel like a deer in his heart.

Zhao Yange is not a saint, and naturally he does not have the consciousness of fighting for socialism like Marx and Engels, if he is still indifferent in that situation just now, it can only prove that he is sick in that aspect.

After taking a hot bath and lying comfortably on the bed, he fell asleep, and he had a very strange dream, and when he got up the next day, the sheets were wet.

Early the next morning, Duan Yu appeared in front of Zhao Yange with the statistical results, this product only came back in the middle of the night last year, and simply slept for two hours, and got up before dawn, so the eye circles were a little red and swollen.

500 questionnaires, 20 questions, different audiences, after statistics, the people of Wolong Town are mostly active in the morning and evening, the love of silk is quite high, and in terms of food, fried stinky tofu and fried osmanthus cake occupy more than five layers.

"Duan Yu, let everyone go to the side room, I have something to say!" Looking at the statistics on paper, Zhao Yange was very happy and muttered.

Zhao Yange drew two vertical line segments with arrows on the whiteboard, and said with a smile: "Everyone, this simple text and graphic, called Cartesian coordinate system, is divided into four quadrants: 'one, two, three, four', and our main research field is in this position, the first quadrant!" ”

Cartesian coordinate system!? Quadrant!?

What the hell, it seems that it is the first time I have heard these two words, what is the young master doing studying him for no reason?

"Young Master, what's the use of this thing?" There are many diligent and motivated people in the family, Zhang Wei heard these two words, and his first feeling was actually very disgusted, but the curiosity in his heart forced him to ask such a question.

Zhao Yange laughed: "Good question!" It's math ... This horizontal line is divided into 12 paragraphs by me, representing the 12 hours of the day, and this vertical line represents the flow of people on Luosi Street, you can see that the flow of people in the morning and evening has reached its peak, which proves that these two times are the best time to do business and sell things! ”

The smooth curve connects the flow of people that changes over time, and there are many smart people among the maids in the family, and when Zhao Yange said this, he actually understood a little, and this small picture is simply clear about the development of the situation.

"And after Duan Yu's questionnaire survey, it was found that the place with the largest number of haunts is Phoenix Lane, which is close to Qingle Fang, which means that this is a prime location for doing business!" Zhao Yange frowned and said.

In the era when traffic is basically by walking, and communication is basically by roaring, there is no convenient mobile phone software such as APP and Alipay, which is convenient for ordering takeout, and it is all up to a pair of eyes to discover and discover.

This also made Zhao Yange a little difficult, the Zhao family's house is very large, but there is basically no one on the main street of Luosi, and it is said that most of the empty houses on the main street of Luosi are sold, but the price is more than three times the price of other places.

It seems that that place is a bit like Beijing's CBD!

"The young master wants to buy a house on Luosi Street?" Yuhuan is good at observing words and feelings, and looking at Zhao Yange's stunned gaze, he knows what he is thinking in his heart.

"Yes, it's just that this matter seems to be a little difficult, the price of the house on Luosi Main Street is very expensive and very popular, we don't have too much money, I'm afraid that those homeowners won't sell the house to us!"

As soon as he thought of bending his waist again because of money, he frowned fiercely!

"The young master can do what he likes, I heard that the old man Su in Phoenix Lane wants to sell a gatehouse, this old man has no children and no daughters, he lives by waking up with his nephew, and he likes to play poetry and chess on weekdays, the young master may wish to have a good relationship with him, so that Master Su may look at each other and sell the house to us at a low price!"

Ancient times were also popular set almost? Zhao Yange scratched his head, he didn't agree or disagree with Yuhuan's suggestion, he and Master Su are no longer at the same age, even if they want to do what they like, they must touch Master Su's vein, otherwise, the horse's ass is very likely to be slapped on the horse's buttocks.

Sometimes I imagine things to be extremely beautiful, but in the end, I still have to accept my fate, Zhao Yange doesn't know if this matter will have a good result, so let's try it first.

He told the family about the purpose of the Cartesian coordinate system, and briefly talked about the one-dimensional equation, which is not unfamiliar to kindergarten children, and even made the family and the maid in the year of the weak crown shake their heads and sigh, and applauded.

After assigning homework to them, the family members went down, and this side room was given a charming and resounding name by Zhao Yange - "Teaching and Research Department"!

Sitting on the rocking chair in the room, Zhao Yange recalled what Yuhuan said while shaking the folding fan in his hand, and was at a loss for a while, then he left lightly with two bottles of rice wine.

Since Lao Huang entered the Zhao family, Zhao Yange rarely went to see him, it has been more than half a month or so, Lao Huang has been doing work in the kitchen in obscurity, it is really unseemly, the food cooked by this old man has a trace of the noble taste of the court.

After a while, when Zhao Yange entered the room, Lao Huang was making soup for Zhao Yange according to Yuhuan's instructions, and when he saw the young master coming, he hurriedly washed his hands that had become dark because of his work, and immediately greeted him: "Young master! ”

"It's been more than ten days since I entered the Zhao family, are you still used to living there?"

"The young master has nothing to say to us, not only let people bring me wine every day, but also gave me the "Sword in the Snow" to relieve my sorrow and boredom, Lao Huang's current life, even if I am a fairy, I will not change!" Lao Huang nodded and smiled.

"When you have nothing to do, go out for a walk, buy what you like, don't be afraid to spend money, it's not easy for people to live, especially in the twilight of life, they start to miss the things of their youth, and you can tell me if you have any suffering!"

Lao Huang's eyes were moist, he couldn't speak for a long time, his hands were pushed and retracted, Lao Cheng was cute, and said quietly: "Don't worry, young master, Lao Huang never sees outside... But the young master suddenly came to the kitchen, but what do you want to ask me? ”

Zhao Yange looked a little embarrassed, he was actually seen through his state of mind, and when he saw Lao Huang's question mark face, he said bluntly: "I want to buy a house, but the owner of the house is the same age as you, I want to ask people of your age what they like, and I will also prepare some gifts to visit!" ”

"At my age, will I still look forward to a woman with money?" Lao Huang looked up for a long time, and his eyes began to moisten, "What we lack the most is someone who can chat, if we have children and daughters, of course I hope to see children and grandchildren!" ”

Zhao Yange felt very uncomfortable, this should be the helplessness of the empty nesters!
