Please help me with the task: Set the droid to self-destruct.

Hello, I’m working on this task:

Change 2 math operations to get the correct result. Do not change anything but 2 math operations in this task. Oh, you might need to know that C# first appeared in the year 2000.

Here is my code:

public class KillTheDroid
   public static void Main(string[] args)
       int half = 1005 - 5;
       int secondHalf = 500 / 2;
       int answer = half + secondHalf;


Can anyone please help me to solve it?
