How do I write the problem: How many different arrangements can I have of 2 couples? I know the answer is six. I don't know how to express.

I'm teaching myself linear algebra.  I'm trying to give myself a simple problem regarding combinations and permutations.  If I have two couples (boy/girl for illustration purposes) how can I write the problem so that I can "do the math" instead of brute force?
