This gave the impetus for the development of determinant theory. With the help of determinants, one can determine whether a linear system of equations can be solved unambiguously and can state the solution explicitly with the help of Cramer's rule. Here, the difference between two or even several wines is compared and determined by means of ratio calculation (proportion).
