"SpletThe determinant of the square sub-matrix of the order one is the minor of the entry e 22 and it is denoted by the M 22. M 22 = e 11 . ∴ M 22 = e 11. Therefore, the minor of the element e 22 in the matrix A is e 11. Thus, the minor for each entry in the second order square matrix is evaluated in the mathematics. " - The leading principal minors
