# Set Intersection/Examples/3 Arbitrarily Chosen Sets of Complex Numbers

## Example of Set Intersection

Let:

 $\ds A$ $=$ $\ds \set {3, -i, 4, 2 + i, 5}$ $\ds B$ $=$ $\ds \set {-i, 0, -1, 2 + i}$ $\ds C$ $=$ $\ds \set {-\sqrt 2 i, \dfrac 1 2, 3}$

Then:

$B \cap C = \O$

and so it follows that:

$A \cap \paren {B \cap C} = \O$
