To prove that for all sets A and B, \( (A - B) \cup (A \cap B) = A \), we can follow these steps: ### Step 1: Understand the Notation - \( A - B \) (also written as \( A \setminus B \)) represents the elements that are in set A but not in set B. - \( A \cap B \) represents the elements that are in both sets A and B. - The union \( \cup \) of two sets combines all elements from both sets without duplication. ### Step 2: Express the Left-Hand Side ...
