Matrix mul question

Name: Op 2012-02-21 4:17

Mom is in the ER with what I hope is not a stroke and I am waiting and working on homework because it's all I can do. No books and insufficient notes. Smart phone not making things easier. Appreciate any help.
I am multiplying matrices. Do transpositions alter any commutivity? It's a one by three times a three by three times a three by one( the outer ones are transpositions of each other).

It's not a stroke but it is sepsis and pneumonia. I worked on the problem and I figured since I got a single one dimensional solution that either order was not important or transposing then proceeding with the multiplication left to right was at least correct in this instance.

Matricies are not commutative.
