Speaking of tangents (sort of)...

I understand logically that NULL (as an unknown quantity) added or used in any other mathematical formula should = NULL.

But I still wish that SQL would use it as a zero since in the real world when we add 5 + NULL we want to see 5, not NULL. How often is NULL actually used as it is intended anyway in this context?
