  For small matrix (n ( 4), the determinant can easily be calculated by Laplace expansion that requires the definitions of minor and cofactor. Minor: The minor Mij of the element aij of the determinant D of order n is a new determinant of order n-1 obtained from D by deleting the ith row and jth column from D. Example: D = ( M13 = ; M22 = Cofactor

  Property 4 – Interchanging Two Rows or Columns Negates the Determinant. This is related to the factor (- 1)I(() that appears in the definition of the determinant. Proposition 6. If one interchanges two rows of a determinant, this negates its values. Similarly if one interchanges two columns. Proof.

  In order to see that a product has the same sign in both det(A) and det(AT), let's look at a typical product in a 4(4 determinant . One such product is (– 1)3a14a21a32a43. This product is multiplied by (- 1)3 since in three pairs of subscripts the second numbers are in the opposite order as the first numbers.
