I am going over some of my notes, and I cannot understand unions, here is the selection I am having trouble with

View attachment 7601

How does the union of four different sets equal just one of the sets? Should the union of 4 sets be the four different sets instead of one.

I am missing something fundamental to unions and intersections.

Thanks for your help!
