RE: Matrix Division on the 28C/S (and later)
AFAIK, the "/" key essentially inverts the matrix containing the equations then multiplies the inverted matrix by the array of values. The HP-48 manual does say that it uses 15 digit internal precision and is more accurate than inversion followed by multiplication.
