What are you doing? Sometimes you are multiplying by two, sometimes dividing by two. This is really confusing. THERE IS ONLY ONE MATRIX TO CONSIDER. I think you are paying more attention to the latex than the problem.

I've been trying to do the calculations in my head, so it's a little tricky for me to get the matrix straight...

Not matrices, matrix. There's only one. I don't know why you are trying to multiply it by two. A(A(P)) is not the same as 2*A(P).

The multiplication by 2 was "accidental", I got mixed up with another similar question I was doing.
