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?

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.
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.
