Question: row echelon form

Question:row echelon form

imccool 12 Maple
I was given the matrix: A= 1 0 -2 -1 -1 1 1 0 1 1 -3 -2 0 -3 3 3 and told to reduce A to row echelon form using the AddRow function several times. I tried maple's help with no luck. Can anyone help me get started or at least clarify the AddRow function. Thanks, ian
