1. Read the topic carefully: Before answering the question, you should first read the topic carefully and understand the requirements and conditions of the topic. Sometimes, some key information may be hidden in the details of the topic. Only by reading carefully can we find clues to solve the problem.
2. Clear your mind: clear your mind when answering questions and clarify the steps and methods of solving problems. You can first break down the problem into several small problems, then solve them one by one, and finally merge the results.
3. Using formulas and theorems: Mathematics is a rigorous discipline, and there are many formulas and theorems that can be applied to solving problems. When solving problems, we should use these formulas and theorems flexibly to improve the efficiency and accuracy of solving problems.
4. Pay attention to units and symbols: pay attention to the conversion of units and the correct use of symbols when answering questions. Sometimes, the wrong unit or symbol may lead to the wrong answer.
5. Check the answer: After completing a question, carefully check the correctness of the answer. The accuracy of the answer can be verified by substituting numerical values, reverse derivation and other methods.
6. Do more exercises: Mathematics is a subject that needs constant practice. Doing more exercises can improve the ability and proficiency of solving problems. You can choose some classic exercises to practice, or you can take part in some math competitions to improve your level.
In short, the answering skills of junior high school mathematics need to be improved through continuous study and practice. Only by mastering the correct problem-solving methods and skills can we get good grades in the exam.
