This scalar-valued function possesses a kind of linearity called n-linearity, and is often defined recursively using cofactor expansion along any row or column. Given two vectors, it can be used to calculate the area of the parallelogram determined by those vectors. For any matrix A, A is invertible if and only if this quantity is nonzero. FTP, identify this quantity, which for a 2x2 matrix with r
