   +--------------------------+

   the numbers are:   6  9  4  6  2

   the math is:  sqrt(9) x sqrt(4) x 2 - 6 = 6
   
   observe...
      sqrt(9) = 3
      sqrt(4) = 2
      3 x 2 = 6
      6 x 2 = 12
      12 - 6 = 6

   more math:  sqrt((4 + 2) x 6) = (9 - 6)!

   observe...
      4 + 2 = 6
      6 x 6 = 36
      sqrt(36) = 6
      9 - 6 = 3
      3! = factorial(3) = 3 x 2 x1 = 6
