## Determinant | Algebra | Chegg Tutors

A determinant is a scalar number that is calculated from a square matrix. A determinant is different from a matrix in that a determinant has a numerical value, whereas a matrix does not. Determinants play an important role in finding the inverse of a matrix and determining whether systems of linear equations are solvable. There are two ways to write a determinant: “det A” or |A|. The determinant of a 2×2 matrix is the product of the elements on the main diagonal minus the product of the elements off the main diagonal.

|a b|
|c d| = ad – bc

There are numerous formulas for calculating determinants for larger matrices.
