Really? I thought the last 2-3 questions were dodgy compared to typical VCAA standard. Still accessible but definitely harder than previous years.

yeah, if A has it's two non zero integers on different rows, there are four non zero integers in AB
if A has it's two non zero integers on the same row, there are two non zero integers in AB

q8 Matrices was fun
I thought question 8 was quite interesting how something like that could happen.
