Abstract
Sarrus-s method is a rule to compute the determinant of a 3x3 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 3x3 matrix, by write out four entries of a 3x3 matrix. We expand the Hazrijaz-s method into fourteen method to compute determinant of a 3x3 matrix.
