MATRICES AND DETERMINANTS
The minor of element 4 is:
The minor of element 5 is:
Each element is given a sign based on its position in the original determinant.
The sign is positive (negative) if the sum of the row plus the column for the element is even
(odd). This pattern can be expanded or reduced to any size determinant. The positive and
negative signs are just alternated.
