Abstract. In this paper, We present a new method to compute the determinant of a 4 × 4 matrix, that is very
simplest than previous methods in this subject. This method is obtained by a new definition of fraction and also by
using the Dodgson’s condensation method and Salihu’s method.
Keywords: 4 × 4 matrix, determinant, Dodgson’s condensation, Salihu’s method
