All beautiful girls want to post with me

Math problems, I hope you can do it yourself, and it will become easier soon!

At first glance, it's over, it's sloppy, and I can't understand a word.The topic can be down-to-earth, but it can't be down-to-earth!

Second look, huh?It seems that I know how to write it?

Looking at it with the third eye, hey, I gradually understand everything!

Yuigahama Yui tried to write down the problem-solving steps in the blank area with a pen. Although she was a little nervous, she kept telling herself to calm down, calm down, and write according to the thinking that Izumi Kotokai taught her just now.

Don't panic, take out the mentality of copying homework before class, and be as stable as an old dog!

"The number of non-empty subsets of C is ... 15."

Yuhihama Yui wrote down the answer he had calculated with trembling little hands, then turned his head to look at Izumi Kotokai carefully, and asked in a low voice:

"Qinhai...do you see what I wrote?"

"let me see."

Hequan Qinhai came over and got very close to Yui, causing Yui's face to turn red involuntarily, but Qinhai didn't notice, and all her attention was on the problem-solving steps and answers written by Yui .

Before she asked Yui to write, she had already looked at the question and figured out the steps and answers in her mind.

Seeing that Yui's solution was correct and the steps were similar to what she wrote, Hequan Qinhai was overjoyed.

Children can be taught, it seems that Yui is not stupid in her head.

"Congratulations, you have calculated the correct answer. Can you tell me how you solved the answer?"

When Yuihama Yui heard that the answer he had calculated was correct, he breathed a sigh of relief, and immediately felt motivated to continue studying.Then he cheered up and told Qin Hai all his thinking and ideas when doing the questions.

Chapter 133 Good Wife and Mother Xiaoqinhai

After listening, Hequan Qinhai nodded, and found 10 set exercises for Yui, and asked her to do it.

10 exercises, 7 correct and 3 wrong.

The reason why these 3 questions are wrong is also because she sloppyly did not review the questions well. After asking Yui to do the calculation again, she quickly calculated the correct answers to these 3 questions.

Yubihama Yui learned quickly, and Izumi Qinhai continued to explain to her quickly. When she saw math problems that she couldn't understand before, it gradually became easier. Yui also became more motivated as she learned more.

The one hour for make-up lessons quickly passed.

"Is it a bit late?" After Yuigahama Yui finished writing the last question on the paper, he raised his head and looked out the window at the getting darker sky.

She originally thought that one hour of make-up lessons would be very long, but she didn't expect that now, she just felt that the time passed so quickly.

Obviously, during class, I feel very boring and the time is very long.Why does Hequan Qinhai give her a lecture, and she feels that time passes quickly?

"It's almost 6:[-], it's a bit late. Fortunately, I called home before I came." Hequan Qinhai didn't look up, and continued to correct the two big questions written by Yui just now.

The two big questions are all correct answers, it seems that Yuigahama Yui has mastered this part of the knowledge.But you can't relax. Before the exam, you must make sure to do a lot of questions to consolidate your knowledge.

"Well written, both questions are correct." Hequan Qinhai put down the pen in his hand and praised.

"Yeah!" Yuigahama Yui cheered.

Unexpectedly, I, who seldom passed mathematics before, could write two big questions correctly at once.

In the past, I didn't even dare to think about it!

"You have to continue to review mathematics these few days. Only by striking while the iron is hot can you get better results in the exam. The next tutoring time is Thursday, and I will start teaching you Mandarin and English on Thursday."

"I always feel that Qin Hai looks like a real teacher. Are you going to be a teacher in the future?"

be a teacher?

Hequan Qinhai shook his head without thinking too much: "I don't have the idea of ​​becoming a teacher, I hope to be able to work as a freelancer in the future. Of course, if you have any questions about your studies in the future, you can always ask me. "

"Then... Qin Hai, aren't you my exclusive teacher?!" Yuigahama Yui discovered the key point.

"If you like to think that way, you can." Hequan Qinhai smiled slightly, then stood up from the chair, and said to Yui: "Wait a minute, are you going to prepare dinner?"

"Yeah, after a short rest, I'm going to start preparing today's dinner. Xiao Jiehua and I eat dinner at this time every day."

"Speaking of Xiaojiehua, why didn't I see her today?" Hequan Qinhai asked.

With Xiao Yuhua's character, when she knew she was coming, she would definitely come out and shout, "It's Little Penguin Sister!" '

"Xiao Jiehua is sleeping in her own room. Because she played too crazy in the kindergarten today, I picked her up from school in the afternoon, and when I carried her home, she fell asleep on my back. I brought her You go and see her."

Speaking of Xiao Yuhua, Yuigahama Yui couldn't help laughing.

This was the first time that Xiao Jiehua fell asleep on her back.

Xiao Jiehua's room is right next door. When she gently opened the door, she saw Xiao Jiehua covered with a quilt, lying on the bed and sleeping soundly.

"It seems that she will sleep until tomorrow morning." Hequan Qinhai whispered.

"Yes. I really envy the children in the kindergarten. They can sleep when they are tired from playing, and play well after they are full." Yuigahama Yui said with some memories and yearning.

When I was young, the last thing I wanted to go to was kindergarten, and I wanted to stay at home every day.But before graduating from university and stepping into the society, I was already a little envious of the life in kindergarten just because I was still in high school.

Students envy adults, and adults want to go back to their school days.

This mutual thinking can be called global unity.

"I'll also leave after eating at your house." Hequan Qinhai said suddenly.

"Eh?" Yuigahama Yui didn't react for a while.

"What? Not welcome?"

"Of course it's not that you are not welcome, you are very welcome! It's just that there are no good ingredients at home to entertain you, Qinhai, just wait for me, I'll go shopping for vegetables right away!" Yubihama Yui said, and was about to run downstairs, ready to go out grocery shopping.

"Okay~" Hequan Qinhai hurriedly stopped Yui, and said, "I'll just eat something casually, how about this, you have a good rest, and I'll cook."

"Qin Hai, can you cook?" Yuigahama Yui asked in surprise.

"Doesn't it look like I can cook?" Hequan Qinhai asked with a chuckle.

"But...Qin Hai, you are a guest, how can there be any reason to ask guests to cook?"

"I'm not a guest, don't be so obtrusive~ I'm going to cook, you can rest well." After Hequan Qinhai finished speaking, he directly picked up the chair he had been sitting on just now and put it back in the kitchen.

I sent a text message to Akina Izumi on my mobile phone, saying that after dinner at Yuihama Yui's house, I took off my school uniform jacket and tied my apron.

The kitchen is not big, the tables and chairs for eating are placed outside, and the kitchen area for cooking is only seven or eight square meters.

First, I found the rice from the rice bag. After washing the rice with water, I put it in the rice cooker and started cooking.

While cooking, Hequan Qinhai opened the refrigerator, and it was just as Yui said, there were not many ingredients left in the refrigerator.Because Yui is responsible for buying vegetables every time, and Yui prefers to buy ingredients every Wednesday when the supermarket holds weekly big sales and big discounts.

With the cheap price after the discount, you can buy fresh ingredients. The supermarket on Wednesday is definitely crowded.

However, although the ingredients seem to be relatively small, this is also good. At least you can clean the refrigerator before buying new ingredients tomorrow, so as to save the ingredients you bought when you can't finish them, and accumulate more and more, and finally fill the entire refrigerator.

Waste is one thing, and Hequan Qinhai has a deep understanding of how terrifying a full refrigerator is.

In particular, Izumi's refrigerator is a refrigerator with double doors on the left and right. Every time I open the freezer, I have to be careful, lest the frozen meat on it fall off and hit her little feet.

The feeling of being hit by a little foot may not be too obvious when it hits the instep. What if it hits the toe impartially...

Just thinking about it makes me gasp.

It's not that I gasped because of the horror, but that it hurts from being smashed!

When Izumi Kotokai squatted halfway, looking for suitable ingredients from the refrigerator, Yuigahama Yui came downstairs out of curiosity, stood at the door of the kitchen, and looked at Izumi Kotokai who was getting busy.

Hequan Qinhai found two potatoes, a green pepper, two eggs left in a box of eggs, and a tomato from the refrigerator.

The potatoes were peeled and shredded, and the green peppers were also shredded. With the blessing of culinary skills, Hequan Qinhai's knife skills were comparable to that of a senior chef.After heating up the oil, saute the shallots and garlic, add shredded potatoes and shredded green peppers, and add various seasonings. If you like the crispy ones, you can add a little water when stir frying.If you don't like the crispy taste, you don't need to pour water, just stir fry directly.

Green pepper and potato shreds are fried and put on a plate.

Then, make a tomato scrambled eggs.

Wash the tomatoes, cut into pieces, and set aside.Two eggs fell into the bowl, Hequan Qinhai stirred with chopsticks, the chopsticks collided with the ceramic bowl, making a clanging sound.

Then, put on the frying pan and pour some more oil, because eggs are more oily, if you don't pour more oil, the eggs may not be fried.The oil temperature is slightly smoking, and the chopped green onion is fragrant. Pour in the beaten eggs and stir fry quickly.

The eggs become golden and fragrant, take them out, put in the tomatoes, stir-fry, pour in the eggs again, quickly stir-fry, season, and call it a day!

Izumi Kotomi's movements are methodical, and he is as comfortable as a chef. He is also humming the chorus song "and I'm home" by Sakura Kyoko and Miki Sayaka in "Magical Girl Madoka".

"I want to walk with you hand in hand. How many times have I felt this way? And the warmth that exists here, even if it's a misunderstanding, it doesn't matter, as long as we are with each other. The tone of tears, the color of sighs. Confirmed here now The current residence, every day is like a joke."

Because there is no "Magic Girl Madoka Magica" in this world, when hearing Izumi Kotokai singing, Yuigahama Yui only felt that Izumi Kotokai was singing a song that she had never heard, but it was very nice.It sounds very warm and cheerful, but there is always a sense of regretful sadness in the singing and melody.

When Yuigahama Yui recovered from the singing, she looked at Izumi Kotokai whose back was facing her, watching her back while cooking.

I always feel that Izumi Qinhai's figure is like a good wife and mother who is cooking.

"Sister, what are you doing standing at the kitchen door?" At this moment, Xiao Jiehua, who was awake, also rubbed her eyes and went downstairs, it seemed that she was hungry and wanted to eat.

As soon as she got down, Xiao Jiehua saw her sister standing at the door of the kitchen.

"I really want to foresee it, I really want to foresee it, the future..." Hequan Qinhai sang very devotedly, when he picked up the plate with tomatoes and scrambled eggs, he quietly turned around.

The next moment, the singing stopped abruptly.

At the door of the kitchen, Yuihama Yui stood there looking at her, and Xiao Yuka, who was sleepy, was also standing beside her. After seeing Izumi Kotokai, Xiao Yuka immediately regained her spirits and shouted happily:

"It's Little Penguin Sister!! Little Penguin Sister, you sing so beautifully!"

puff--

Hequan Qinhai almost spit out a mouthful of old blood.

This embarrassing scene made her want to carry the train overnight and leave the city.

Fortunately, Hequan Qinhai, as a scumbag heroine, is so thick-skinned that she is astonished as a heavenly being.

It's a mere embarrassment, what a shame!

Hequan Qinhai put the dishes on the table calmly, as if nothing happened just now, and said to Yui and Xiao Yuhua:

"Are you hungry? Come and eat quickly, just finished, wash your hands quickly, and eat while it's hot."

"Yeah, I'm pretty hungry." Yuigahama Yui nodded quickly and said, pretending that she didn't hear anything just now.
