    That would be the union of set A and set B wouldn't it?

    Right but union in math really just means the same thing as it does in English 'to join'.

    What do you get when you join A and B?

    Think of it like this A U B is like saying A joined with B. If A was a set of red marbles and B was a set of blue marbles what would the set of A U B consist of?

    blue and red

    Correct. Joining them does not change their form to purple or something. We still have red and blue marbles. So apply that to a small set of numbers A={1,3,5} and B={2,4,6}. Now what is A U B?

    Right now expand that to a larger set A={all even numbers} and B={all odd numbers}. Now what is A U B?

    Right or {all numbers}. Now just apply the appropriate terminaology (i.e. that used in your question), and you have your answer.

    If A={negative even integers} and B={negative odd integers} what does A U B contain?
