Problem
Let's consider two number sets: \(A = \{1, 2, 3, 4\}\) and \(B = \{3, 4, 5, 6\}\). What is the union of these two sets?
Solution
Step 1 ：The union of two sets is a set that includes all the elements from both sets. So we just need to list all the unique numbers from set \(A\) and \(B\).
Step 2 ：First, list down all the numbers from set \(A\): \(1, 2, 3, 4\).
Step 3 ：Then, add the numbers from set \(B\) that are not in \(A\): \(5, 6\).
