Best ResponseYou've already chosen the best response.1can you give an example? I know there are row operations 1. you can swap rows 2. you can multiply a row by a number 3. you can add 2 rows to create a new row that will replace the one of the old rows.

Best ResponseYou've already chosen the best response.1that's just REF  row echelon form... if you want RREF (reduce row echelon form) you must have 0's above and below the 1 [similar to an identity matrix]

Best ResponseYou've already chosen the best response.1dw:1434517367302:dw that 0 isn't doing anything wrong... as long as you don't have a 0 in the main diagonal...which breaks one of the rules... you must have a 1 on the top left corner
