Magic Numbers

I found a flash site back in May 2006 that does a little trick with numbers. It is called the Flash Mindreader, if you are interested, below is the data needed to solve the presumed magic. Good Luck!

			public void ShowMagicNumbers()
			{
			    for (int i = 1; i < 100; i++)
			    {
			        int mod;
			        mod = i % 9;
			        if(mod == 0)
			        {
			            Response.Write(i);
			        }
			        else if(mod == 8)
			        {
			            Response.Write(i);
			        }
			        else
			        {
			            Response.Write(i);
			        }
			    }
			}
			public void GetMagicNumbers()
			{
			    for (int i = 10; i < 100; i++)
			    {
			        Response.Write("Original Number = " + i);
			        string j, k, l, r;
			        int a, b, c, m;
			        j = i.ToString();
			        k = j;
			        l = (k.Remove(1,1));
			        r = (k.Remove(0,1));
			        a = Int32.Parse(l);
			        b = Int32.Parse(r);
			        c = a + b;
			        m = i - c;
			        Response.Write("Magic Number = " + i + " - (" + a + " + " + b + ") = " + m);
			    }
			}
