    Would anyone here know where I can see the worked method of this proof for determinants? Either online or a book. Thank you

    a11+/-b11 a12 a13
    a21+/-b21 a22 a23
    a31+/-b31 a32 a33

    =

    a11 a12 a13
    a21 a22 a23
    a31 a32 a33

    + / -

    b11 a12 a13
    b21 a22 a23
    b31 a32 a33

    If you're looking for a general determinant proof you have no idea how
    deep this rabbit hole can go, seriously...
    How have you defined the determinant?
