n=1 and how to come up with matrix
I would like to see a hint on the difference of n=1 vs n>1.
Also, please motivate how you come up with A. Talk about the kernel of A-B.
Done - do students know what a kernel is at this stage?

Better, but why so complicated? Show it for a 2x2 matrix, then say for larger n just add zeros.
