Before returning to the college entrance examination, I became popular in the science circle

Chapter 15 Advanced Mathematics
Gao Ming took another look at Wu Tong. A child who loves to learn is always attractive. She couldn't help but say a few more words: "My child, are you going to participate in the competition? If so, you don't need to buy it, and walk on the road of benevolence and harmony." , is the county library, there are these textbooks in it, you can apply for a borrowing card with your ID card, and borrow them directly!"

These are college textbooks. For students who only need them for a while and will distribute them when they go to college, it is not a very cost-effective thing to buy. The library has comprehensive textbooks, and borrowing is also very simple, so it is more appropriate.

Wu Tong slapped his head. She was thinking wrong. Why did she forget the library?
As the face symbol of county culture, the county library has a fairly rich collection of books.There may not be any rare books, but there are still many books for the general public that involve various aspects.Comrade Wu also often borrows books on agriculture and machinery from the county library. How could she forget this?

It seems that the teacher said at some time that with their student ID card, they can also borrow books in the library.

With her reading speed, buying is indeed not a wise and cost-effective decision.Her family's money is all earned by her parents' hard work, unnecessary waste can still be saved.

Wu Tong sincerely thanked Gao Ming: "Thank you, auntie!" She really thanked this auntie.

"You're welcome. There are very few people in the county who buy the textbook you want, and there is nothing in the store. My child is about the same size as you. If I can love learning like you, I will be Amitabha!" Gao Ming waved his hand, She's just saying something.

Wu Tong went out and turned around to ride in the direction she was going. The library was at the other end of the same avenue as Yi Gao, which was actually quite close to her home.The county library is not too big, with a three-story building that also includes office areas for staff and a warehouse.

Wu Tong had been here before, but at that time it was as a small accessory for Comrade Wu, purely for fun, and to read some story albums by the way.

Wu Tong was also unfamiliar with this place, so he went directly to the administrator for consultation.

There are not many people in the library, and it can be said to be a rare clean place in the county.The administrator is extremely laid-back. Most of the people who come here are familiar faces. They are very clear about the layout of the place and their own needs. They basically don't need her. Their work is more about book registration and environmental organization.

It is rare for someone to come to inquire, and the administrator is quite enthusiastic: "The advanced mathematics you want is on the third shelf in the D area, and the numbers such as university mathematics are all in that area!"

Someone in the library was reading a book, and the questions and answers between the two were conducted quietly.Wu Tong followed the directions, turned to area D, and found the textbook she wanted.

Advanced Mathematics, Analytic Geometry, Linear Algebra... She pulled out Advanced Mathematics and looked at it first. To have a thorough understanding, it is estimated that you have to enter the state of in-depth study in order to better understand in-depth research.

Wu Tong took a total of three textbooks including analytic geometry, linear algebra, and advanced mathematics to the registration office to register. She had asked just now that the time for borrowing books was half a month.Although there are still a lot of books about mathematics on the shelf in area D, Wu Tong is not greedy for more. He will take three books for research and study, and then exchange for others.

When she first came into contact with these advanced mathematics knowledge, she set aside more time for herself, and then adjusted her borrowing strategy according to her own progress.

After leaving the library, Wu Tong couldn't help but use the side of the book to block the direct sunlight from the lower deck.

In the September weather, Qiuhuo's tail is still vicious. She just came and went back and forth, eager to borrow books, but she hasn't felt much yet.Now that I came out of the cool and cool library, the sun was extremely dazzling.

Fortunately, they were the first ones to be built, and the green trees on both sides of the road can shade the sun, otherwise people would not have the courage to go out.

On the way, Wu Tong bought herself an old popsicle to relieve the heat, and now she only cares about such a refreshing taste.In her memory, the summer weather only gets hotter every year, so she still needs to practice the Chaoyang Ziqi method well, so as to cultivate the realm of not being invaded by cold and heat.

"Tongtong, you're back. Have you eaten?"

Wu Jingzhong heard the sound of the door opening and leaned out from the kitchen.Teacher Jin Yu had a meeting before get off work in the morning. She had just arrived home and was resting in the living room.

"Are you feeling hot? Sit down and cool down. Dad will open some watermelon for you first!" He had a break from work today, so he went to the morning market to buy a small watermelon and put it in a cool place in the room. It will be delicious when he eats it.

This kind of small watermelon has thin skin and sweet flesh. It is easy to eat one by yourself. It is best to eat with a spoon in two halves. It has always been Wu Tong's favorite.

"Don't blow into the wind, be careful of headaches!" Jin Yu followed closely, and Wu Tong came back from the heat, and he likes to stand at the air vent for coolness, which is the easiest way to get sick.

"I know!" Wu Tong took the watermelon handed over by his father, took a bite and put it in his mouth.Then she opened her wallet and handed back the book purchase fee that her parents gave her when she went out in the morning.

"Didn't have time to go to the bookstore today? You take it and buy books later!" Jin Yu handed the money back again. The cost of her child's study was the expenditure she least cared about.

"I was wrong. I can borrow the books I want from the library. A kind aunt in the bookstore reminded me that there is also the library!" Wu Tong ate the watermelon, waved his hand, and asked his mother to give the money After taking it back, she found a more convenient place, so she didn't need to spend money.

"I've already applied for a loan!"

Hearing what Wu Tong said, the couple obviously understood that the child had gone to the bookstore and then to the library. After all, the daughter was running back and forth on the road all the time, and there was no time to eat.The two felt sorry for their children, and Wu Jingzhong hurried to the kitchen to serve Wu Tong and Teacher Jin a meal.He is at home today, and he is the cook.

The couple has a good relationship, and they have been following a negotiated relationship with each other since they got married. They do laundry, cooking, cleaning, and shopping... all at their own time and convenience.In terms of the nature of his work, Wu Jingzhong is closer to home and his schedule is more regular. Wu Tong, on the other hand, Wu Jingzhong has cooked more since he was a child and has developed good cooking skills.

When it comes to housework, Wu Jingzhong never shirks.

After dinner, after Wu Tong talked with his parents, he went back to his room, hooked up the Enlightenment Stele, and entered the state of in-depth study.

Wu Tong opened the advanced mathematics she had borrowed. She borrowed the sixth edition of Tongji, which was published two years ago. The content of Chapter 1 caught Wu Tong's eyes, about functions and limits.
