Understanding Union and Intersect
- Practice reading three-circle Venn diagrams and identifying which regions are shaded
- Write set notation using union (∪), intersection (∩), and difference (−) to describe shaded areas
- Combine multiple set operations in one expression, like B∪(A−C)
- Understand the difference between union (everything in both), intersection (only the overlap), and difference (in one but not the other)
