To prove that for all sets A and B, \( (A \cup B) - B = A - B \), we will follow these steps: ### Step 1: Understand the Left-Hand Side (LHS) The left-hand side of the equation is \( (A \cup B) - B \). This represents the elements that are in the union of sets A and B, but not in set B. ### Step 2: Define the Union of Sets The union of sets A and B, denoted as \( A \cup B \), includes all elements that are in A, in B, or in both. ...
