Determinant is a scalar value that can be calculated from the elements of a square matrix. The development of determinants took place when mathematicians were trying to solve a system of simultaneous linear equations. The shape of every determinant is a square. If a determinant is of order n then it contains n rows and n columns. For every square matrix A of order n x n, there exists a number associated with it called the determinant of a square matrix.
