"You're talking about this equation, so calculate, in fact, math problems, basically use the knowledge in the book to solve, you just need to memorize the example problems in the book, do more extensions, and practice the amount of questions. ”

Su Shunyu was rarely a little distressed: "The school teachers only teach the knowledge in the books, and they don't have any exercise book exercises. ”

"I'll give you a few. As soon as Lin Jin heard it, he understood that when he was studying, the most important thing was these exercise books and test papers.

Nowadays, it is not like in later generations, students are inundated with test papers, and now there are very few test papers, and they can't do any questions if they want to, so they can only look at the example questions in the textbook repeatedly.

So much so that a set of test papers for the college entrance examination is very important.

Su Yi listened beside him, and suddenly there was an extra way to make money.

Her eyes lit up slightly, and when Lin Jin gave the question and asked Su Shunyu to do it, Su Yi whispered: "Uncle, there is a way to make money, do you want to try?"

"What is the way to make money?" Lin Jin came over in an instant, he still wanted to study, but he didn't want to put pressure on his family, not to mention that he was going to get married, and he would have to support his family in the future, and it would be better to earn a little more money.

"Na, look, you are very good at reading, produce some primary school test papers, make sure it's no problem, big brother goes to school to do questions, those students with good grades will definitely want to buy it, and you will make money then." ”

"But we don't have a printing press, can we copy by hand?" Lin Jin was also moved by Su Yi's words, this is indeed a way to make money, now the state allows private individuals to do small business, but those who dare to do business are basically in the minority.

Everyone is unanimously optimistic about the iron rice bowl.

Su Yi said: "Uncle, when do you have time to take me to the scrap station, if you can buy a broken printing press from the printing house, my father will repair the machine, and when the time comes, everything will be solved, and you can print as much as you want." ”

"Think about it, an exercise book, uncle, you sell it for five cents a piece, the cost is two cents, and one book will make a net profit of three cents, you rent a bicycle, pull the exercise book to sell, sell one for three cents, ten copies for three yuan, and one hundred copies for thirty yuan, which is worth a month's wages. ”

"You don't have to rent a bike, let's go buy a discarded bicycle and my dad will fix it." Su Yi snapped his fingers, settled accounts with Lin Jin, and said: "Uncle, you go and sell exercise books to those parents, they want their children to be admitted to college, they will buy them, you go to the city to sell them, those people have money." ”

When Lin Jin heard this data, his heart was already moved, he reached out and rubbed Su Yi's little head, hugged her face and kissed her: "Xiao Yi'er, if my uncle makes money, I will buy you meat to eat, you are really my uncle's lucky star." ”

"Uncle, I gave you a way, I don't want meat, you sell an exercise book, just give me two cents. Su Yi has long thought about it, to make more money, only then can he have money to buy discarded electrical appliances in order to make more money.

"Okay, as long as I sell a copy of my uncle, I will share it with Xiaoyi'er. Lin Jin smiled and rubbed her head.

The corners of Su Yi's mouth hooked up a smile: "Thank you, uncle." ”

"Thank you, Xiaoyi'er is so smart, follow you, uncle, I may not be able to realize all my dreams. Lin Jin said that he would do it, borrowed a textbook from Su Shunyu, and began to write test questions.

"They're all out to eat. ”

It didn't take long for Su Shunlin to call for someone to eat.

At noon, the men still eat in the hall.

Lin Xiu took his children to eat in the kitchen, and Lin Jin was called over by Su Jinnian to drink and eat together.
