   private void run()

        {

            double n1 = 0;

            double n2 = 0;

            double n3 = 0;

            Console.WriteLine("Input some numbers");

            n1 = double.Parse(Console.ReadLine());

            n2 = double.Parse(Console.ReadLine());

            n3 = double.Parse(Console.ReadLine());

            Console.WriteLine("Answer is {0}: ", Calculate(n1, n2));

            Console.WriteLine("Answer is {0}: ", Calculate(n1, n2, n3));



       

        }

        private double Calculate(double n1, double n2)

        {

            return n1 + n2;

        }

        private double Calculate(double n1, double n2, double n3)

        {

            return n1 + n2 + n3;

        }

Calculate() has parameters for adding two numbers or three numbers. If you hover over "Calculate(n1, n2));" you can use the up and down arrow key to switch parameters.

Note: this does not work return types. Having two calculate methods but each with a different return type will not work

Optional Parameters is a method that contains parameters that are not mandatory. To create optional parameters you need to give them a default value and they have to be declared after the mandatory parameters.

    

private double Calculate(double n1, double n2, double n3 = 0, string message = "The Answer Is ")

        {

            Console.Write(message);

            return n1 + n2 + n3;

        }

As you can see I did not do anything with the message parameter.

    

Console.WriteLine("{0}: ", Calculate(n1, n2, n3 = 10));

You can also fill parameters by using their name followed by a colon. You can do this out order.

    

 Console.WriteLine("{0}", Calculate(n2: n2, message: "Final Answer: ", n3: n3, n1: n1));

I did this because I finished the chapter on methods and thought making a tutorial would help me absorb what I learned :p. Hopefully this helps others as well.
