  1. well, in that first column I would like to see
    1
    0
    0

    so I would multiply row 1 by 2
    subtract the result from row two
    and put that result where row 2 is

    then I would multiply row 1 by 3 instead of by 2 and subtract the result from row three, placing the result in row three.
