Throwing a NullReferenceException

This code won't let me move on from the problem and it's throwing a NullReferenceException.

Program.cs 
using System;

class Program
{
    static void Multiply(double first, double second)
    {
        Console.WriteLine(first * second);
    }
    static void Main(string[] args)
    {
         Multiply(2.5, 2);
         Multiply(6,7);

    }
}

It looks like the only change made to the provided code so far is different parameter names, which is not part of the assignment. You'd see the same error if you just submit the original code unchanged.

This first part of the task is to change the Multiply method so it will "return the multiplied value instead of printing it". The instructions give you a head start by pointing out that "Its return value type should be double" (instead of "void").

Then, you will need to modify the Main method to make use of the return values, and to add them together instead of printing them individually.
