Best ResponseYou've already chosen the best response.1correct!!!! just one small tip so you can save some time.....for example if you're having a test or exam the time is fixed and you want to this in the fastest possible way....try to multiply the first row with 2 , 4 and 3 at once and add to the other rows in one step...you'll save some precious moments....:D

Best ResponseYou've already chosen the best response.4i tend to divide off the other rows to get a 1 in the lead and then do the adding; but that can make for some scary fractions to deal with
