Im Really not understanding what i need to do here! I've set the static from void to double, string, int etc and I don'

Program.cs 
using System;

class Program
{

    static return Multiply(double firstParam, double secondParam)
    {
        Console.WriteLine(firstParam * secondParam);
    }

    static void Main(string[] args)
    {
       return Console.WriteLine(Multiply(2.5, 2));
       return Console.WriteLine(Multiply(6, 7));
    }

}

Hey Paul,

static double Multiply(double firstParam, double secondParam)
{
    return firstParam * secondParam;
}

static void Main(string[] args)
{
    double a = Multiply(2.5, 2);
    double b = Multiply(6, 7);
    Console.WriteLine( a + b );
}

Your Multiply function need to be with a return type of double, at the moment you have "return", then inside of the function you need to use the keyword return to return those values in the function, hope this helps

That worked perfectly Telmo, Thank you very much. My mind was only going round changing the static element and i could't grasp in my mind to set double a, b to equals multiply. I think i will resit this module until i fully understand it. Once again, Thank you.
