Calling functions through Delegates

    class A
    {
        //Declared the Multicast Delegate(Void Return type)
        public delegate void MyDelegate(int a,int b);
        public static void Main(string[] args)
        {
            B b = new B();
            MyDelegate Handler;
            Handler = new MyDelegate(b.Add); //Added address of first function.
            Handler += new MyDelegate(b.Subtract); //Added address of first function.
            
            Handler(3, 4); //Calling functions.
            Console.ReadLine();
        }
        
    }
    class B
    {
        public void Add(int a, int b)
        {
            Console.WriteLine("Sum is:{0}",a + b);
        }
        public void  Subtract(int a, int b)

            Console.WriteLine("Difference is:{0}", Math.Abs(a - b));
