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.

Keywords: matrix, determinant, Sarruss method
