title: Double data type calculator C#
body: <p>Hello I am fairly new to C# programming and I need some help with my calculator. I'm try to use double data members and method, but when I use it nothing happens. Could someone explain what I am doing wrong? </p>
  
  <pre><code>static void Main(string[] args)
      {
          Double FirstOperand;
          Double SecondOperand;
          Double Result;
  
          FirstOperand = Convert.ToDouble(Console.ReadLine());
          Console.Write("What is your first number?");
          SecondOperand = Convert.ToDouble(Console.ReadLine());
          Console.Write("What is your second number?");
          Result = FirstOperand + SecondOperand;
          Console.Write("Result is {0}", Result);
      }
  </code></pre>
