WebTo calculate a determinant you need to do the following steps. Set the matrix (must be square). Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero. Multiply the main diagonal elements of the matrix - determinant is calculated. Webthe value of determinant is = a (ei − fh) − b (di − fg) + c (dh − eg). Note: (i) The number of elements in a determinant of order n is n 2. (ii) A determinant of order 1 is the number itself. Properties of Determinants There will be no change in the value of the determinant if the rows and columns are interchanged.
