Ruan Qingyue took the math book, looked at the table of contents first, and took a general look at the knowledge points of the book.

In fact, junior high school mathematics, whether it is algebra or geometry, is very simple and basic, just simple operations, cognitive real number functions, compared with high school, it is simply too pediatric.

After reading this catalog, Ruan Qingyue knew what to tell him, of course, before starting the lecture, she still had to touch his bottom first, and at the same time, she hoped that Lin Hongrui, who was tall and handsome, would not be a mathematical idiot.

Otherwise, if you teach it, it will be difficult for her to die!

Do you remember what negative numbers are and how they are calculated? What is 1 minus 6? Ruan Qingyue asked him.

"Negative 5, I know this." Lin Hongrui replied immediately.

"Good." Ruan Qingyue nodded with satisfaction, and then asked him if he knew what fractions, integers, primary, quadratic functions, inverse proportional functions, unary quadratic equations, unary quadratic equations, and so on.

Lin Hongrui probably only knows half of it, and he doesn't know the rest if he asks deeper.

After Ruan Qingyue probably knew about his situation, she immediately came up with a few integer addition and subtraction methods that he still remembered, a one-dimensional equation, and asked him to solve them to see his level of problem-solving.

Lin Hongrui took the piece of paper with more than a dozen questions written on it, and walked to the table on the side, because there was no high chair, he could only bend over, half-tie up the horse steps, and lie awkwardly on the table to solve the problem.

He was serious here, and after Ruan Qingyue on the bed stared at him a few times, he began to yawn uncontrollably.

One, two, yawning more and more, tears coming out of her eyes.

So sleepy.

But hold back!

Take out a serious attitude of a strict teacher!

Ruan Qingyue straightened her waist, but after waiting for about five minutes, she yawned again, and her eyelids were about to start fighting, seeing that Lin Hongrui was still doing the question, she couldn't help but start urging:

"Is it done? It's normal to forget. Come and I'll show you how to do it, talk about the rules of arithmetic, and don't waste yourself on hard solutions. ”

"Wait, it's going to be over soon." Lin Hongrui twisted his eyebrows and said.

After more than ten seconds, he straightened up, took the paper to Ruan Qingyue, turned back to the table, came over with a kerosene lamp, stood beside the bed, his body was very straight to illuminate her, his expression was serious and there was a hint of apprehension, he looked like a student who was waiting for his homework to be approved.

Ruan Qingyue glanced at him, and saw that he was tall and handsome, but he looked immature and pious, and only felt that a strong contrast and cuteness were revealed from him, rushing towards her, so that she couldn't help but her aunt's heart was overflowing, and she almost stretched out her hand to pinch his face and say a good word.

After glancing at him several times, Ruan Qingyue looked down at the problem he solved, just now she wrote him a total of ten arithmetic, from simple to difficult, although he changed the last one once, but he did it right.

Ruan Qingyue is very satisfied, he is smart, and she also saves worry and trouble.

In the later equation solving, the last two questions involved fractions, which cost him some effort, and finally he got it right!

"Great! Full marks! It's better than I thought, when you do the question, where do you have doubts? Ruan Qingyue smiled and praised him sincerely.

Lin Hongrui said the doubts he encountered in the question, Ruan Qingyue pointed them out to him one by one, and finally summarized the operation rules for him, and wrote them on the blank space of the paper, which is an important note.

"Let's ask a dozen more questions." Lin Hongrui stared at those rules for a few moments, and after writing them down, his eyes lit up, and he looked at Ruan Qingyue with a wistful expression, and spoke.

“…… All right. Ruan Qingyue wanted to shout in her heart, she couldn't be cute, I really wanted to sleep!
