If any two rows/columns of a square matrix A of order n(>2) are identical; then its determinant is 0.

Let A be a square matrix such that each element of a row/column of A is expressed as the sum of two or more terms.Then; the determinant of A can be expressed as the sum of the determinants of two or more matrices of the same order.
