Every square matrix has a determinant but computing a matrix that is larger than2 x 2 can be difficult. Most students learn the Laplace expansion and Gaussian method for computing these determinants. These methods are effective but are prone to many mistakes especially when fractions show up in the Gaussian method. Alice's Adventure in Wonderland's author, Lewis Carroll, invented a method to compute the determinants for these large matrices. It is named after his given name, Charles Lutwidge Dodgson. The Dodgson Condensation comes across some issues when working with zeroes in the matrix. This talk will cover the original method, theorem and solution for the zero issue. Then it can be determined whether the Dodgson Condensation is an easier method for computing these determinants.
