A determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's.
