Zhou Yao said in a panic: "He left a note and ran out without saying a word. I just went out and asked the guards, and they said that Xiaoyu left with the soldier who was setting up the stall."

When Jiang Minke heard that it was Ning He who took Xiao Yu away, she breathed a sigh of relief: "Was it Xiao Ning who took him away?"

Zhou Yao heard that Teacher Jiang's tone on the other end of the phone had softened a lot, and she felt a little unconvinced.

Under normal circumstances, Teacher Jiang would never allow Xiaoyu to go out, no matter who took him out.

She originally thought that Teacher Jiang would be angry when she found out that it was that country bumpkin who took Xiaoyu out.

But what Zhou Yao expected did not happen!

She was unwilling to give in and had to light the fire!

"Teacher Jiang, Xiaoyu's learning progress has been too slow throughout the summer vacation. The summer vacation is almost over. If we don't hurry up, Xiaoyu will fail the small test at the beginning of the school year again."

Jiang Minke asked, "Then why didn't you stop Xiaoyu from going out?"

Zhou Yao had already thought of the words: "When I went to the toilet, Xiaoyu wrote a note and ran out. Xiaoyu never did this before. He never ran out without saying a word."

Zhou Yao's words had a hidden meaning. She was telling Jiang Minke that someone must have instructed Jiang Zhengyu to do this.

The suspicion of instructing Jiang Zhengyu to do this naturally fell on Ning He.

However, Jiang Minke didn't believe that Ning He would do this. Isn't she clear about her own son?

The way Xiaoyu looked greedy, he must have been trying to follow us.

Jiang Minke didn't say anything to Zhou Yao, but said that she would go to the market and bring Xiaoyu back.

Zhou Yao also quickly said, "I'll leave now and meet up with Teacher Jiang at the market."

…

When Ning He and her friends arrived at the market and set up their stalls, there was still some time before the workers got off work.

Ning He borrowed a table and chair from the man selling fruit nearby for Jiang Zhengyu to use for his homework.

And they are waiting for customers at noon.

Jiang Zhengyu opened his homework book and looked at the densely packed questions on it. He was dizzy.

Jiang Zhengyu scratched his head while holding the pen, frowning. He couldn't understand any of the questions.

Qianlin squatted beside Jiang Zhengyu and looked at him for a long time, but he didn't see him start writing.

"Brother Xiaoyu, why don't you start writing?"

Jiang Zhengyu frowned and said awkwardly, "I don't quite understand the question."

Qianlin glanced at the title in the booklet in shock: "I don't understand? How can I not understand this?"

"Isn't this just the simplest arithmetic problem?" Qianlin was shocked.

This exclamation also attracted Ning He's attention. She leaned closer to take a look and found that it was true.

The math problems of this era were relatively simple. They were all basic arithmetic problems. There were no questions that tested logical thinking, such as application questions.

But Jiang Zhengyu couldn't even solve the simplest arithmetic problem!

Qianlin pointed to a question and quickly gave the answer.

Jiang Zhengyu listened to Qianlin's answer and wrote it down.

Ning He shook her head helplessly. She called Qian Lin, "Lin Bao, this is Brother Xiao Yu's homework."

After receiving Ning He's reminder, Qianlin immediately shut up.

Without Qianlin's help, Jiang Zhengyu couldn't solve any of the problems.

Ning He walked to Jiang Zhengyu, bent down slightly, and looked at the questions in his booklet.

She told him patiently and gently, "These questions are not difficult. As long as you find the right method, you can solve them quickly."

Jiang Zhengyu looked distressed: "How can it not be difficult?"

As he spoke, he pointed to a question and said, "This question, one thousand minus five hundred and thirty-four, how do I calculate this? I can still calculate it for addition, but I can't figure out the subtraction no matter how hard I try."

Ning He glanced at it and suddenly smiled. She said to Jiang Zhengyu, "I'll teach you a formula that can be used for subtraction of hundreds, thousands, and tens of thousands."

When Jiang Zhengyu heard this, his eyes lit up instantly. He asked curiously, "What formula is so powerful?"

"The units digit of the number being subtracted adds up to ten, and the preceding digit adds up to nine."

Seeing that Jiang Zhengyu was still confused, Ning He patiently asked him, "Let me ask you, how many numbers can make ten when added to four?"

"Six!" Jiang Zhengyu answered quickly.

"So what does three add to make nine?"

"It's still six!"

"What's five minus nine?"

"Four!" Jiang Zhengyu's eyes lit up when he saw the number four hundred and sixty-six that Ning He wrote on the paper.

Ning He said to Jiang Zhengyu, "Now add five hundred and thirty-four and four hundred and sixty-six together, do they equal one thousand?"

Jiang Zhengyu instantly became alert. He calculated and found that it was indeed equal to one thousand!

"It's amazing! This method is so effective!" Jiang Zhengyu looked at Ning He with eyes full of admiration.

Ning He smiled and touched Jiang Zhengyu's head: "So you know how to do it now, right?"

Jiang Zhengyu nodded vigorously: "Yes, I understand!"

After he finished speaking, he picked up the pen and started to do the questions quickly.

Ning He withdrew his gaze, it was soon time for lunch.

Soon, a long queue formed at Ninghe's stall again, and customers who had bought breakfast in the morning expressed their praise for the tea eggs.

"Madam, your new tea eggs this morning are so delicious. Do you have any left? I want to buy a few more to take home!"

When the people in the queue behind heard that someone wanted to buy a few more, they became a little unhappy.

"No, if you buy a few more, the ones behind us won't be available."

"That's right, we haven't tasted it this morning, you have to let us have a taste!"

"Madam boss, you have to make sure everyone can buy it. This new product must be available to everyone. Otherwise, who will buy it next time?"

Ning He had already made sufficient preparations. She smiled and said to them, "Today, each person is limited to buying two eggs, so that everyone can buy one. If there are eggs left at the end, everyone can buy more."

Hearing Ning He's assurance that there would be enough tea eggs, they breathed a sigh of relief and lined up with peace of mind.

Fang Ming walked out of the factory and saw a long queue of people waiting for snacks, so he walked forward.

The workers who saw Fang Ming greeted him warmly.

"Teacher Fang, aren't you going to eat in the cafeteria at noon today?"

Fang Ming said to them, "It's my friend's food stall, so of course I have to come and support it more often."

When the workers heard Fang Ming say this, they suddenly reacted.

"No wonder Teacher Fang came here to help this morning. It turns out she's friends with the lady boss!"

"Since he is Mr. Fang's friend, of course we have to come along and show our support!"

Fang Ming said to them, "You don't have to be so deliberate in showing your support. They are all women and children setting up stalls outside, so it's inevitable that they won't be able to take care of everything. Please be more tolerant and be a little patient when queuing. We who work here know that it's not easy to make money, and it's the same for them. Give them some time and be more tolerant. Speed ​​is something that is learned through practice."

Ning He looked at Fang Ming in surprise. Fang Ming's words made Ning He look at him with new eyes.
