doesn’t matter what we multiply the vector [1 1 1] by, it will never result in the vector [2 1 2] . Moving to the third column we can see that [3 3 3] is just 3 times the first vector [1 1 1] . We have encountered our first column that is a linear combination of another! And lucky last, vector [4 2
