Ok, maybe a dumb question, but anyway:
if I have some matrices equation like this: AB = BC if I want to multiply both sides by some matrix Z can I stick it in the middle? AZB = BZC I know I can do these two: ABZ = BCZ ZAB = ZBC but can I do the middle too? Thanks!

Have you tried some examples to see if it works?

but the proof worked out nice, so I am wondering if I am actually not doing it right. Good point. I just rely on the fact that people here know everything and know it off top of their heads, so it would save me trouble But usually, I make an effort before I ask here. I am just pressed for time: reviewing before finals.
