  <p>I don't understand why <code>Console.WriteLine(Сalculate)</code> does not output. Thank you for answer.<br>
  The code here:</p>
  
  <pre><code>public static double Calculate(string userInput)
  {
      var parts = userInput.Split(' ');
      var sum = double.Parse(parts[0]);
      var rate = double.Parse(parts[1]);
      var time = double.Parse(parts[2]);
      return sum * (1 - Math.Pow(rate/ rate, time)) / (1 - rate/ rate);
  }
  
  static void Main()
  {
      Calculate(Console.ReadLine());
      Console.ReadKey();
      Console.WriteLine(Сalculate);
      Console.ReadKey();
  }
  </code></pre>
