What should be paid attention to in the partial complement and complete set of senior high school mathematics set?
1, pay attention to the relativity of complete set and complement set. The complementary sets of relatively different complete sets in the same subset are different.

2. Complement set is the relationship between sets and the operation of sets.

3. Using venn diagram and number axis to understand the complete works and complement sets is intuitive and clear, which embodies the idea of combining numbers with shapes.
