Really understand the method of solving problems, review in class after finishing a topic, retell the idea of solving problems, and copy the wrong book for the wrong topic. After a period of hard work, the problem-solving error rate will be reduced and good study habits will be developed. Learning mathematics is simple: what you can do is right, and what you miss won't be wrong again.

1. Pay enough attention to calculation.

I have always thought that calculation problems are much easier than the analysis of application problems, and I have a solid understanding of some laws and laws, so calculation is a breeze. So I was either overconfident or unable to concentrate when calculating, and the results were full of mistakes.

2, according to the general order.

First of all, make clear the meaning of the question and see if there are any special requirements such as simple method and keeping several decimal places; Secondly, observe the characteristics of the topic and see if there are several simple algorithms for operation; Third, determine the operation sequence. On this basis, the relevant rules and laws are used for calculation. Finally, carefully check whether there are any mistakes, omissions or miscalculations.

3. Develop the good habit of careful calculation.

Some students make mistakes because they are not careful in calculus. The data is unclear and the identification is wrong. When drafting, you can't arrange the vertical tables in a certain order, which leads to the adhesion between the top and bottom, the misalignment of the same numbers, which is not convenient for inspection and easy to read the wrong data. I suggest that everyone must form the good habit of writing numbers vertically.
