The error is in your code, you are explicitly telling oracle that the bind variables are varchar2, so why would Oracle evaluate it?

Try this ...

DECLARE

nnum1         NUMBER;
nnum2         NUMBER;
nresult       NUMBER;

BEGIN
    BEGIN
    nnum1 := 0;
    EXECUTE IMMEDIATE

        USING nnum1, OUT nresult;
        dbms_output.put_line(TO_CHAR(nresult));
     END; 

    BEGIN
    nnum1 := 1;
    nnum2 := 1;
    EXECUTE IMMEDIATE

        'begin SELECT :1 + :2 INTO :0 FROM dual; END;'
        USING nnum1, nnum2, OUT nresult;
        dbms_output.put_line(TO_CHAR(nresult));
     END; 

END;
/
