namespace Consts
{
   public class PI
   {
      public static double value = 3.14159;
      private PI() {}  // private constructor
   }
   public class three
   {
      public static int value = 3;
      private three() {} // private constructor
   }
}
namespace MyMath
{
   public class Routine
   {
      public static long Add( params int[] args )
      {
         int i = 0;
         long Answer = 0;
         for( i = 0; i < args.Length; i++)
         {
            Answer += args[i];
         }
         return Answer;
      }
      public static long Subtract( int arg1, int arg2 )
      {
         long Answer = 0;
         Answer = arg1 - arg2;
         return Answer;
      }
   }

class MyApp

      long Result = 0;
      Result = MyMath.Routine.Add( 1, 2, 3 );
      Console.WriteLine("Add result is {0}", Result);
      Result = MyMath.Routine.Subtract( 5, 2 );
      Console.WriteLine("Subtract result is {0}", Result);
      Console.WriteLine("\nThe value of PI is {0}", Consts.PI.value );
      Console.WriteLine("The value of three is {0}", Consts.three.value );
