Find the elements in A union B
Answer by CPhill(1959)   (Show Source):
You can put this solution on YOUR website! A ∪ B (A union B) includes all the elements that are in set A, or in set B, or in both. We simply combine the elements of both sets, making sure not to list any element twice.
* A = {z, y, x, w, v, u}
* B = {x, w, v, t, s, r}
A ∪ B = {z, y, x, w, v, u, t, s, r}
