Whenever you see a 
(union) of two sets, find all the elements that are in either or both sets. When you see a 
(intersection) of two sets, find all the elements that appear in both sets.
For example,
 (A \cup B) \cap C = ({1,2,3} \cup {3,4,5,6}) \cap {3,5,7} = {1,2,3,4,5,6} \cap {3,5,7} = {3,5})
(make sure to follow the order of operations; do the parentheses first)
Sorry the { } symbols didn't appear, they are used everywhere in LaTeX to denote lots of other things, e.g. 
is inputted as \sqrt{49}.
