Similarly, I feel helpless and angry at people like you. Let alone how many school-age children in our country can't afford to read or go to school for the time being. Let's talk about your school resources and your tuition (although your family doesn't have to pay tuition now, this tuition is paid by the state. Where did the country get the money? Can you enjoy or even waste it with peace of mind in exchange for taxpayers' money and national resources? ), you eat, wear and use, although these are all paid by your family's money, these money and materials are paid by people who have ardent hopes for you and people like you with their labor. Don't say these things are none of your business. In fact, these things are closely related to you. The reason is simple, because everything is closely related. Don't think this is superstition.
After reading this, I don't know if you understand my hard work for the final solution of this kind of problem, and if you have any sense of shame or responsibility with those who ask or want to ask the same question.
In fact, as far as things are concerned, it is foolish of you to do so. Let's not say that what you did violated the fundamental meaning of doing the problem, failed to live up to the fundamental intention of the questioner and the person who asked you to do the problem, and hurt those who had ardent hopes for you. Judging from the probability that you can get the desired result by asking this question, you are also extremely stupid. This question "Practice and test the answer in class", I want to ask, do you expect to get the answer with great probability? Let me help you analyze it. People who can give you satisfactory answers generally need to meet the following conditions: (condition 1), often surf the Internet and often browse the Q&A section of this website (let's just say so); (condition 2), be happy to answer other people's questions; (Condition 3). I have had or (recently) had the so-called "class-reaching exercises and tests" like you (math scores in the second volume of the eighth grade); (Condition 4). Have the answers attached to the book "Class Exercise and Test" (math scores in the second volume of the eighth grade), or be willing to copy the answers yourself; (5) It has the equipment to convert the answer into a format that can be spread on the Internet, or it is willing to manually input the answer into a computer and forward it to you, or it is willing to deliver the text carrier of the answer to you by mail or some other way .....; (Condition 6). The class-time exercises and tests that you have reached the standard (the math score in the second volume of the eighth grade) are exactly the same as those that people who can give you ideal results (the math score in the second volume of the eighth grade), which just matches. That's all I can think of for the time being. I hope you can think about it yourself. If you don't know probability, you can look up the basic knowledge about probability yourself.
Well, I don't want to say more. I'm glad if you can understand. It took me half an hour after all. I'll be glad if you can't understand or even think I'm meddling. Because it shows that you have read and thought carefully, which at least shows that you have an opinion, although this opinion may not be right. As long as you have your own opinions, you won't wait for a completely unreliable standard answer.
Thank you, until the end, this document is for people who have the same behavior as you. I hope I can refer to it and think about it.
