Mono C#: Unexpected Symbol

So this is my first question on StackExchange. I'm a Programmer who uses many Programming Languages, so I'm a bit ashamed that I'm missing what could be happening here. I'm using Mono on Xubuntu 18.04, and whenever I try and compile the Code below, it throws back a bunch of errors about Variables I declared, and the else keyword. I followed along with a C# tutorial on YouTube, and it's driving me crazy trying to figure out where the error(s) are. Here's the code, which I edited a bit to personal taste:

using System;

class A_Better_Way

{
  static void Main(string[] args)

  {
    Console.Write("Enter a number:");

    double num_one = Convert.ToDouble(Console.ReadLine()); //Doubles allow the use of decimals

    Console.Write("Enter \"+\", \"-\", \"/\" or \"*\":");

    string operator = Console.ReadLine();

    Console.Write("Enter another one:");

    double num_two = Convert.ToDouble(Console.ReadLine());

    if(operator == "+" ) //If Statements: Easy as magic. Easy as Jiff.

    {
      Console.WriteLine(num_one + num_two);

    }

    else if(operator == "-")

    {
      Console.WriteLine(num_one - num_two);

    }

    else if(operator == "/")

    {
      Console.WriteLine(num_one / num_two);

    }

    else if(operator == "*")

    {
      Console.WriteLine(num_one * num_two);

    }

    else

    {
      Console.WriteLine("You fail at life.");

    }

    Console.ReadLine();

  }

}

Any help would be most appreciated. And, I'm glad to be here.

Welcome to SO!

operator is a keyword in C#, so you cannot use it as variable name. https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/operator

For a future, please specify error messages you got. It will help others to understand your problem and give an accurate answer.
