I am new to C#, sorry if this is duplicate. I am simply trying to add two variables together but I get the error from the title
An object reference is required for the non-static field, method, or property 'Program.x'
Here is code
using System;
namespace HelloWorld
{
  class Program
  {
    int x = 3;
    int y = 10;
    static void Main(string[] args)
    {
        int mathResults = x + y;
        string results = mathResults.ToString();
        Console.WriteLine("Hello World!");    
    }
  }
}
Could someone please explain WHY I am getting this error? Thank you!
