    Exclamation Principal minors

    hi all,

    this looks obvious but i am not getting it. so L.P.Ms are 1,3,2. i started diagonally from the left :
    i got 1, 3...and then for the last i got :

    1(16) + 3( 1) + 5(3) = 14+3+15

    this isn't equal to 2!! what am i doing wrong?

    thanks
