Let `A = {1, 2, 3, 4, 5, 6}`, `B = {2, 4, 6, 8}`. Find `A - B a n d B - A`.

Explanation

To solve the problem, we need to find the sets \( A - B \) and \( B - A \) given the sets \( A = \{1, 2, 3, 4, 5, 6\} \) and \( B = \{2, 4, 6, 8\} \).

### Step 1: Find \( A - B \)

The set \( A - B \) consists of elements that are in set \( A \) but not in set \( B \).

1. **Check each element of \( A \)**:
- **Element 1**: 1 is in \( A \) and not in \( B \) → Include 1.
