Luo Dongqing didn't understand Tang Youyou's words a little, but Tang Youyou's praise for her cuteness still made her blush a little.

"What's the matter, don't make me happy. ”

Tang Youyou: "......"

Are you really fake?

It is indeed difficult for people to know themselves clearly.

Tang Youyou didn't talk about her, the two chatted, and they were almost at Li Da's house.

Luo Dongqing said: "Youyou, you are so powerful, you can memorize the road after only one visit!"

Tang Youyou: "......"

You may not believe it, but I used to live here.

When they went to the door of Li Da's house, they knocked on the door, and Li Da opened the door for them and led them to the bedroom.

On this hot day, it is a bit unbearable to have no air conditioning.

"Okay, let's start directly, I just flipped through the book, and found that the compulsory three courses are algorithm and probability problems, these two types of questions are sent to the score of questions, it's too simple, you can just follow the class in the future." ”

Tang Youyou: "???"

Luo Dongqing: "???"

You seem to be kidding me? Then we have so much preview in the morning, and you don't talk about it?

Moreover, where it is simple, it is obvious that I can't understand it......

"Although the exam has passed, there are still a lot of content that you haven't mastered in the first and second compulsory courses, so I just picked out some questions for you according to your situation, let's start. ”

Li Da directly took out two pieces of paper, which were different topics.

"After that, you exchange questions, mark the question number, and I'll explain it to you later. ”

Li Da had already arranged it clearly, Luo Dongqing and Tang Youyou had to listen to him, take a look at the topic, and sure enough, they still didn't grasp it well before.

The compulsory two is slightly better, because Li Da focused on talking to them before, and the content of the compulsory one hasn't been talked about much yet.

The main content of Mathematics Compulsory 1 is sets and functions.

The set is still relatively simple, and the first multiple-choice question in the general college entrance examination is the set, which is a simple question that will definitely be tested, and the set is often combined with the function to produce the question.

Therefore, those topics were all found by Li Da for them from the top of the three or five.

Luo Dongqing: "You said this is a question to be sent?"

Luo Dongqing and Tang Youyou are doing the questions seriously, and Li Da is the same.

It's the same topic, and Li Da naturally has to do it again so that he can tell them. Of course, Li Da will read the answer, and it will be embarrassing if he miscalculates.

Of course, in mathematics, as long as the idea and process are correct, it is basically not wrong, unless you make a mistake and make a small calculation problem.

It took Li Da more than half an hour to finish all the questions, and then looked at Luo Dongqing and Tang Youyou, and they all fell into a state of contemplation.

Li Da was idle anyway, so he leaned over to see if Luo Dongqing was stumped by something, and as a result, when he saw it like this, Luo Dongqing became even more nervous.

The eyes are still reading the questions on the paper, and there are no more questions in the mind.

That is, there is a question outside the heart, and there is no title in the heart.

Uncle Da, what is he doing with me?

I was sweating a little on the road just now, so it won't smell, right?

Oh no, will Uncle Da think I'm stupid?

Luo Dongqing's thinking activity is very intense.

Then, she found out that Li Da went to see Tang Youyou again.

Eh, it's so close!

The hateful Uncle Da really came for Tang Youyou.

You're not looking at the topic, you're looking at the people!

Li Da suddenly felt Luo Dongqing's gaze, he looked at Luo Dongqing, and saw Luo Dongqing puffing out his cheeks and bowing his head to do the question.

"Any questions?"

Li Da came over and smelled the faint fragrance wafting from Luo Dongqing's body.

Li Da didn't take a deep breath.

I, Li Da, am a righteous gentleman.

Not an idiot.

"Nothing. ”

Luo Dongqing lowered his head and continued to think deeply.

Li Da saw that they all started to think and didn't start writing, obviously they couldn't do it, and he was embarrassed to say no, so he simply said understandingly: "Okay, when the time comes, let's start explaining! I'll see how much you have done first." ”

Check it out, Don Yoyo's.

"This second question is a scoring question, why did you miscalculate?"

Tang Youyou: "......"

She knew that Li Da had started again.

She's used to it, though.

emmmm, when did you start to be complained about by Li Da without any fluctuations in your heart?

"The problem of functions is basically wiped out, and it seems that the foundation is really poor!"

Tang Youyou: "......"

There will still be a little fluctuation in the heart.

"Oh my God, I talked about this question before, you can't just forget everything after a summer vacation, right?"

Tang Youyou: "......"

After happily escaping the summer vacation for a long time, Tang Youyou once again experienced the fear of being dominated by Li Da.

Autistic.

And then there is Luo Dongqing's.

“……”

This time it was Li Da who was silent.

Luo Dongqing became nervous instead, and said, "Uncle Da, why don't you speak?"

"Because I said I couldn't be too fierce. ”

Luo Dongqing: "......"

"Can you forget your stuff in a summer vacation?"

Li Da said helplessly.

Tang Youyou and Luo Dongqing were closed at the same time, and Luo Dongqing said weakly: "I still remember a little bit." ”

Li Da: "......"

His choice was right, and revision was the right one.

It wasn't until five o'clock in the afternoon that Li Da ended, because he didn't buy vegetables and didn't plan to keep them for dinner.

Tang Youyou noticed that Li Da was rubbing his waist.

Only then did she remember that Li Da had been standing all the time when she was explaining for their convenience.

In other words, who said the saying that you don't have back pain when you stand and talk?

Do you stand for two hours and talk to see if your back hurts?

"I'm sorry, I'll review it well in the evening!"

Tang Youyou suddenly said to Li Da very seriously, although she was a little autistic by Li Da, she still felt a little sorry for Li Da.

After all, if you review a little during the summer vacation, your state will not be so bad, and it will not make Li Da work so hard.

"Well, there is fighting spirit, yes, come on! But don't be discouraged, these questions are questions from previous college entrance examinations, and it is normal for you to be a little uncomfortable with your contact now. ”

Li Da encouraged her a little.

In fact, compared to Tang Youyou, who was discovered in the end, Luo Dongqing's attention has always been on Li Da, but she didn't dare to say it, what if Tang Youyou "misunderstood" that she had been paying attention to Li Da.

Then, she found out, is Li Da's waist not very good?

If Li Da knew Luo Dongqing's thoughts, he would definitely pinch her face and then rub it flat.

Am I having a bad waist?

It's just that it's a little uncomfortable to hold a position for too long, so I subconsciously knocked it twice.

There is definitely no waist problem at a young age!

"Uncle Da, why don't you go to my house tomorrow?"

Luo Dongqing suddenly launched an invitation, she felt that her family was bigger, and Li Da would not have to stand to give them a lecture.

The considerate Luo Dongqing decided to care about Li Da, who had a bad waist.
