Applying a list of 2D paramters to a mathematica function

         I have (for simplicity) something like this:

         f[x_, y_] := x+y;

         I want to use this function for a variety of parameters in a list:

         indices = {{a,b}, {c,d}, {e,f}, ..}

         so that I get

         {a+b, c+d, e+f, ..}

         Doing the intuitive thing (for me)

         f /@ indices

         results in

         {f[{a, b}], f[{c, d}], f[{e, f}], ..}

         but what I want is

         {f[a, b], f[c, d], f[e, f], ..}

         and that's not what I'm getting. I have tried using Flatten, pure 
functions (Slot # and &), different Map functions, nesting at parameters 
(like {1} and {2}), and other things but I just can't seem to get what I'm 
after. Any help please?

         Thank you,

Curry
