Default Why is a negative times a negative a positive?

We got into this big discussion at lunch last Friday. Apart from saying "because it just is" or "those are the rules", no one at work could really explain this. I have to mention that I work in a Computer company with a lot of smart engineers. We also had some statisticians at the table as well as some Business Intelligence Data Analyst types.

So anyone have a good way to explain why this is?
