when you're multiplying two matrices together does it affect the answer at all if you swap the columns around in one of the matrices?

Sometimes it does. Such as the square of a matrix.E.g. A(BC) equals (AB)C but AB does not equal BA.
Apologises for misunderstanding the question. Glad to feel I can make mistakes and not have my gut knotted.HallsofIvy said:And that has what to do with the question?
