SQL & PL/SQL :: Creating Multiple Functions Within A Package?

I'm trying to create multiple functions, add them then minus 1 in a package. I'm at my wits end as to what I'm not doing correctly as the package gets created fine but the package body is giving me compilation errors.

create or replace package addfunction as
function q1 (num1 IN NUMBER, num2 IN NUMBER) return number;
function q1 (num1 IN NUMBER, num2 IN NUMBER, num3 IN NUMBER) return number;
END;
/

[code].....

Warning: Package body created with compilation errors
