Abstract
A concise analytical formula is developed for the inverse of an invertible 3 x 3 matrix using a telescoping method, and is generalized to larger square matrices. The formula is confirmed using randomly generated matrices in Matlab

Comments
Corrected a few typos throughout. Emphasized in the last section, that indices of matrix elements in an inverse expression may be treated as generalized discrete functions
