I'm confused

In this code in the for loop I need to get the average of the tongue lengths and I don't know how. Please Help

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {

            for(int i = 0; i < frogs.Length; i++)
            {
              frogs / frogs.Length;
            }

        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }
}

Hi Michael, let me help, meaning, I assume you don't want the answer, right? First of all this line: frogs / frogs.Length; does not mean anything hanging in there, an operation not assigned to any variables. Do you understand this?

Then let's think first what we have to do, forget about the code: you have to calculate and average, right? this is the sum of each item, divided by the total number of items. What you can achieve with the for is add up each of the length values to a variable that you will declare, you can call it "totalLengths" or whatever.

If you understand this far then you got it.

I'm sorry I still don't understand how to add all the indexes up.
