output 2,4,6
basic maths but i just seem to be able to get the correct numbers to get the output
 
using System;
namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            int a, b, c;
a = -1;
       b = -2;
       c = 2;
       
 b = 2 * a * b;
            a = (c - b) * 2;
            c = a + b;
            Console.Write(a + ", " + b + ", " + c);
        }
    }
}
