C# Exception Handling:Display Exception Message through Main Method : i have three methods(including main method) where exception handling is done for each. now i want to print the exception messages of other methods through main method.

**Note:** i want to use only one console.writeline() that to in main methods.

     using System;

namespace Execp
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Console.WriteLine(Arthimatic(10, 0));
                Console.WriteLine("Hello World!");
                Console.ReadKey();
            }
            catch (Exception ex)
            {
                Console.WriteLine( " Message " + ex.Message);
                Console.ReadKey();
            }
        }

        private static int? Arthimatic(int num1, int num2)
        {
            try
            {
                int? value = Divide(num1, num2);
                return value;
            }
            catch (Exception ex)
            {
                return null;
            }
        }

        private static int? Divide(int num1, int num2)
        {
            try
            {
                int num3 = (num1 / num2);
                return num3;
            }
            catch (Exception ex)
            {             
                return null;
            }
        }
    }
