SQL & PL/SQL :: SUM Product By DATE By LOCATION

I am trying to query a Oracle database table that contains sample records like the one below...

DATE LOCN PROD1 PROD2
09/12/2011 L1 6 2
09/12/2011 L2 3 7
10/12/2011 L1 4 1
10/12/2011 L2 3 3
11/12/2011 L1 2 2
11/12/2011 L2 2 0
12/12/2011 L1 4 1
12/12/2011 L2 5 0

I am trying to use the Oracle Sum() to get a grouping by DATE, LOCATION, SUM(PROD1+PROD2) for DATE periods 10/12/2011 and 11/12/2011. Below is the desired end result.

DATE LOC1 LOC2
10/12/2011 5 6
11/12/2011 4 2
