Most students are careless when reviewing questions, and it is easy to misread a certain condition in the questions.

Therefore, when students usually do math problems, they can specially prepare a notebook to copy 2-3 problems, and check them with the original questions after copying. To some extent, this can help students avoid mistakes in examination.

Secondly, the topic is right, and it is also a problem that needs to be solved if the problem is not clearly examined. I suggest that students can use the method of mind mapping in the course, list the known conditions of the topic in detail, deduce the knowledge points of investigation, and solve the problem step by step.

Second, the handwriting is clear and neat.

The handwriting is clear, even on draft paper, it should be written neatly. In particular, decimal points, carry points and abdication points should be clearly written and eye-catching. Formulas should be arranged neatly and orderly to prevent mistakes due to scribbling.

Third, check carefully and insist on calculation.

After you finish the problem, check it carefully to see if the result is reasonable, and then check it again. It's best to write a check, don't perfunctory. It is suggested that students can take a two-way test from the middle step, so that they can easily find their own mistakes.
