where did I go wrong?

I keep getting an error CS0103 stating something to the effect that the word Math doesn't exist. What am I missing?

RightTriangle.cs 
namespace Treehouse.CodeChallenges
{
    class RightTriangle
    {
        public static double CalculateHypotenuse( double sideOne, double sideTwo)
        {
            double sideThree = Math.Sqrt((sideOne * sideOne) + (sideTwo * sideTwo));   
            return sideThree;
        }
    }
}

You forgot the "using System;" directive to give the code access to the System namespace (where Math is located).
