2. Formulate problem-solving strategies: According to the type and difficulty of the topic, we need to formulate problem-solving strategies. For example, if the topic is a proof, we may need to use induction or reduction to absurdity. If the topic is calculation, we may need to use algebraic or geometric methods.
3. Implement problem-solving strategies: In this step, we need to solve problems according to our own problem-solving strategies. This may require us to do some calculations or use some mathematical tools and methods.
4. Check the answers: Finally, we need to check whether our answers are correct. This may require us to read the questions again or use different methods to verify our answers.
5. Reflection and summary: No matter what the result is, we need to reflect and summarize. We need to think about whether our problem-solving process is effective, whether our strategy is appropriate, and what we can improve.
