What is Determinants of n×n Matrices Explained about?

1) The determinant of an n×n matrix can be computed recursively by using determinants of smaller matrices. For a 3×3 matrix, the determinant is computed as a11 × M11 - a12 × M12 + a13 × M13, where Mij is the minor (determinant of the minor matrix). 2) Determinants are useful for computing volumes, determining whether a matrix is singular, computing the inverse of a nonsingular matrix, and solving systems of linear equations. 3) Technology like the TI-83/84 calculator, Excel, and online matrix algebra too
