Chapter Seventy-Eight: The Problem of Branches

"Not yet, but I have some ideas. Pen @ fun @ pavilion wWw. biqUgE怂 ļ½‰ļ½Žļ½†ļ½ā€

"Yes, let's tell us all about your thoughts first." Teacher Li handed over the teaching stick.

Su Ran raised his eyebrows, was silent for a few seconds before taking the teaching stick and generously walked onto the podium, "My thinking is actually very simple, to paraphrase a sentence that Teacher Li often says, everything will never deviate from its roots." In fact, these five questions are all evolved from the basic question type, as if the main branches remain the same, but the number and shape of the leaves added later are different. Su Ran took the chalk on the side and drew a few strokes on the first question, "Actually, this is the most basic question type, but other conditions are added on this basis, but it is easy to be misled by those conditions when solving the problem." So as long as you grasp this branch and solve the problem, the problem becomes very easy. ā€

After that, he put down the chalk and handed the teaching stick to Mr. Li, and then walked down.

Teacher Li's eyes flashed with praise, this girl has a good understanding.

After all, people are also people who have learned it once, and the ability to draw inferences from one another is still necessary.

"Su Ran's thinking is very good, in fact, it is like I often tell you, all topics are inseparable from the foundation, that is, the first branches of the big tree, so you must solve this branch problem when you study, so no matter how you add branches and leaves to it later, it will not be difficult for you."

Most of the students below are all able to understand at one point, and after listening to Mr. Li's words, they all have a sense of openness, and everyone quickly picked up the pen and began to answer these questions.

The morning class passed quickly, Su Ran had never thought that the physical chemistry class would pass so quickly, thinking that when he took these two subjects in high school, he often listened to it sleepily, and he couldn't help but feel a little funny.

After going home for a lunch break, the two came early.,The math class in the afternoon is Su Ran's favorite subject.,In fact, only the permutation and combination of the content in the high school course is her most headache.,In her previous life, Su Ran also discussed this problem with her math teacher at the time.,I didn't expect the math teacher at that time to directly ask her to give up the content of this piece.,And said that this still has a certain relationship with IQ.,At that time, Su Ran was really hit ==

The math in the afternoon starts from the set, the content of this part is relatively simple, and Mr. Li's lecture is also very interesting, the same problem he requires not only to make, but to solve at least two ways. Of course, he would provide ideas, so everyone spent the whole afternoon killing their own brain cells and constantly generating.

After an afternoon of classes, I suddenly relaxed and felt quite tired, after packing up my things, Su Ran was still lying on the table and lazily couldn't lift up, and I couldn't look at it anymore, so I squatted down in front of her, "Come on, I'll carry you back." ā€

Su Ran was already wilting, and when he saw that he was squatting down in front of him, he also took advantage of the situation to lie down, and the squad leader said next to him that his eyes were going to be blinded, okay!

When he crossed the deadline and picked up Su Ran and walked past the squad leader, he glanced at the past, and the squad leader snorted coldly, turned around and took a few people's bags and hurriedly followed him home.
