Abstract
This article furnishes a new and simple matrix inversion method which makes full use of the condensation technique of the author of Alice's Adventures in Wonderland, Charles Dodgson. A special feature of this article is the adoption of Bhaskara's Law of Impending Operation on Zero in overcoming the problem of division by zero whenever zero appears as a divisor in the condensation technique of Dodgson.
Keywords: Matrix, determinant, division by zero, Bhaskara's law of impending operation on zero, inverse of matrices, Dodgson Condensation, Cofactor matrix
