adding fields containing NULL values

Hi all!

Let's say I have a table like:

employee date sallary extras
--------------------------------------
Name1 01-31-1999 5000.00 NULL
Name1 02-29-1999 5000.00 500.00
Name1 03-31-1999 5000.00 NULL

I would like to get something like:

employee date total
-----------------------------
Name1 01-31-1999 5000.00
Name1 02-29-1999 5500.00
Name1 03-31-1999 5000.00

Umfortunately 'select employee,date,sallary+extras as total' doesn't give the
desired result because 'somevalue + NULL' is considered to be NULL.
Is there any solution for my (small) problem?

BTW: I'm running PostgreSQL V 6.5.1
