C# C# Collections Arrays Jagged Arrays

Not sure why this working? I can't debug anything so I'm not really why this is not working.

Is the max factor correct the way I have it setup?

Math.cs
namespace Treehouse.CodeChallenges
{
    public static class MathHelpers
    {
        public static int[][] BuildMultiplicationTable(int maxFactor)
        {
            int[][] myTable = new int[maxFactor][];

            for(int i = 0; i < myTable.Length; i++)
            {
                myTable[i] = new int[maxFactor];

                for(int j = 0; j < myTable[i].Length; j++)
                {
                   myTable[i][j] = i * j;
                }
            }
            return myTable;
        }
    }
}

:point_right: Your array is a bit too small.

Since index numbers start at 0, if you want to fill the array with multiplication products based on values up to and including maxFactor, you'll need to size your arrays to one more than maxFactor.
