        {
            int i = Calculator.Add(1, 2);
            double d = Calculator.Add(1.2, 3.2);
            string s = Calculator.Add("ab", "cs");
        }

        static class Calculator 
        {
            public static T Add<T>(T t1, T t2)
            {
                dynamic d1 = t1;
                dynamic d2 = t2;
                return (T)(d1 + d2);
            }
