Abstract
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 con-densation method,but the priority of this method compared
with Dodgsun-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
