There are always mistakes in elementary school math application problems, so it is useful to do more problems, because doing more problems can let you see many problems, and your thinking will be clear next time you encounter problems. If math application problems always make mistakes, in addition to doing more problems, we should also analyze the reasons for the mistakes. Maybe it's because I did the problem too quickly and carelessly, or maybe I didn't analyze the meaning of the problem well, so I can find a solution by analyzing my own reasons. Don't pay too much attention to speed when doing problems. You can take your time and do everything well. Sometimes I get poor grades in exams not because I can't, but because I can't do the right questions. When you do all the questions you know correctly in the exam, you can save time and reduce the occurrence of mistakes. In fact, it is common to make mistakes in math application problems in primary schools. It is very important to sum up experience and find out the reasons for making mistakes. Don't let the bad mood of doing wrong questions always surround yourself. When I was in primary school, I always made mistakes in doing math problems, mostly because of carelessness. Sometimes the numbers of the problems were wrong, and sometimes there were mistakes in simple calculations. At first, I felt very unhappy, because if I did something wrong, I would be told by the teacher. I don't care to take my time, because I have found a way to do the problem, so it is not easy to make mistakes. At first, I avoided making mistakes by doing more questions, because with more knowledgeable questions, I became more and more handy when using formulas. So it is useful to do more questions. Besides doing more questions, it is enough to sum up experience. Doing math problems has a great sense of accomplishment. Every time I work out the answer, nothing can replace that kind of happiness. Therefore, if you want to learn math well, the most important thing is to be able to calm down and do math problems. Don't make yourself unhappy because of a small mistake. You will get better and better after accumulating more experience. Moreover, the questions in primary schools are very simple, so it is not easy to make mistakes as long as you are careful.
