1. Choose a topic or concept: First, determine the mathematical concept or topic you want to study, such as algebra, geometry, probability, etc.

2. List main branches: subdivide a concept or topic into several main branches, such as subtopics, related formulas, theorems, etc.

3. Add detailed information: under each main branch, add more specific information, such as definitions, formulas, examples, etc. You can use keywords, charts or images to help you remember and understand.

4. Use colors and graphics: Use different colors and graphics to distinguish different topics or branches to increase visualization and readability.

5. Add Association: Add an association, such as an arrow or a line, to the mind map to show the connection and logical relationship between different concepts.

6. Simplify the organization: ensure that the mind map is concise and clear, and avoid too many details and redundant information. Delete unnecessary or duplicate branches and keep only the most critical and core content.

7. Review: Review the mathematical mind map regularly to consolidate memory and understanding. You can use different colors or marks to emphasize important concepts or formulas.

Through the above steps, you can make a simple math learning mind map to help you better understand and remember math knowledge.
