In this paper we will present a new method to calculate of n×n (n ≥
3) order determinants. This method is based on Dodgson - Chio’s condensation
method, but the priority of this method compared with Dodgson
- Chio’s and minors method as well is that those method decreases
the order of determinants for one, and this new method automatically
affects in reducing the order of determinants in 2nd order
