Sarrus’s method is a rule to compute the determinant of a 3×3 matrix, by write out six entries of matrix (two columns or rows of matrix). Recently in 2014, Hajrizaj gave three new methods to compute determinant of a 3×3 matrix, by write out four entries of a 3×3 matrix. By position of copied entries from Hajrizaj’s methods, we do combination for four duplicate entries to get fourteen methods of computing determinant of a 3×3 matrix.
