title: Using variables in multiple methods
body: <p>I am trying to use my three variables (num1, num2 and oper) in each of my methods but I can't find a way to do this anywhere in my book or on the internet. I realize there is much to be done before my program is ready and I will get it cleaned up as I learn. Right now I just need to know the code for importing the variables to different methods, I don't need the code fixed or improved. I hope this makes sense, I'm very new to this so forgive my ignorance and bear with me. Thank you very much for reading!</p>
  
  <pre><code>public class SimpleCalc
  {
      public double SimpleCalc(double num1, double num2, string oper)
      {
          Console.Write("Enter first integer: ");
          num1 = Convert.ToDouble(Console.ReadLine());
  
          Console.Write("Enter operator (+,-,*, / or %)");
          oper = Convert.ToString(Console.ReadLine());
  
          Console.Write("Enter second integer: ");
          num2 = Convert.ToDouble(Console.ReadLine());
  
          if (oper == "+");
          return addNumbers();
  
          if (oper == "-");
          return subtractNumbers();
  
          if (oper == "*");
          return multiplyNumbers;
  
          if (oper == "/");
          return divideNumbers;
      }
  
      public double addNumbers()
      {
          Console.Write("The answer is: ", num1 + num2);
      }
  
      public double subtractNumbers()
      {
          Console.Write("The answer is: ", num1 - num2);
      }
  
      public double multiplyNumbers()
      {
          Console.Write("The answer is: ", num1 * num2);
      }
  
      public double divideNumbers()
      {
          Console.Write("The answer is: ", num1 / num2);
      }
  }
