Mathematics is the most important subject, so we should not give it up. First, read the textbook carefully, understand every knowledge point above, and ask the teacher if you don't understand. Second, make a good title. After you finish, check your answers carefully, cross out the wrong ones, think hard, and ask your classmates and teachers if you really don't understand. If you have any questions, you must understand them and never delay them! The problem will only drag on, don't take chances! Third, for some mistakes, you can prepare a set of mistakes and write your own ideas and correct solutions.

The problem processes are compared with each other to find out their own mistakes in order to correct them in time. We should develop good problem-solving habits at ordinary times. Fourth, fill in the blanks. Filling in the blanks is the key, so we should pay attention to strengthening the training of this part of the paper. The fifth question is graded according to the steps. You can write several steps, but if you can't write them, at least set an unknown number, and it's not bad to make an equation group. The steps should be clear and the handwriting should be neat.
