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 difference between the two sets \( A \) and \( B \). The difference \( A - B \) means we take all the elements in set \( A \) and remove any elements that are also in set \( B \). Similarly, \( B - A \) means we take all the elements in set \( B \) and remove any elements that are also in set \( A \).

### Step-by-step Solution:

1. **Identify the Sets**:
- Set \( A = \{1, 2, 3, 4, 5, 6\} \)
- Set \( B = \{2, 4, 6, 8\} \)
