Beat the computer at Sudoku - just add one number

 The computer solution to this puzzle involves calculation of the position of four different numbers     ( 1, 4, 2 and 9 )  under two scenarios. How the computer determined the starting and finishing squares further complicates its solution.

Can you add a number ( not necessarily a 9 ) by a much simpler method which only involves calculating the position of two numbers?
