Code:
Sets:

Give the elements:
E ∪ F
How? ∪ = Union
Thanks 
E= {2, 4, 6, 8....} it is read as E is X such that X is an even integer (I am assuming it is a whole number as well, just in case).
F= {1, 3, 5, 7....} it is read as E is X such that X is an odd integer (I am assuming it is a whole number as well, just in case).
The union of two sets is the addition of all their elements.
Whereas, the intersection is only the common elements.
So, E U F= {1,2,3,4,5,6...∞}
However, E ∩ F= {∅}
