Query: Proposed method to reduce the determinant of order n   This paper presents a theorem which solves the problem of reduction of the
determinant order by means of a transformation of it, into other determinant
whose each element are a determinant of second order. This implies that, if the
process continues, desired result is obtained by solving always determinants of
second order. It also assesses the degree of efficiency compared to the method
by minors and with the method of Gauss, as well as the ability to reflect small
variations in the data. This method should have a good impact also in the area
of teaching mathematics, due to its ease of assimilation and application.
