What are the Steps to Invert a 3x3 Matrix?

Inverting a 3x3 matrix involves a series of steps that can be broken down into manageable parts. The process starts with finding the determinant of the matrix, which is a scalar value that represents the "volume" of the matrix. If the determinant is non-zero, the matrix is invertible, and the inverse can be calculated using a formula that involves the matrix's elements. The resulting inverse matrix is a new 3x3 matrix that, when multiplied by the original matrix, yields the identity matrix.
