When this mathematical quantity is zero, a system of linear algebraic equations has no unique solutions, and, for a scalar, this value is defined to be the scalar itself.
When this mathematical quantity is zero, a system of linear algebraic equations has no unique solutions, and, for a scalar, this value is defined to be the scalar itself. One way to solve for it in a system of equations is to divide this result with the solution values in place of the coefficients of that variable by this result of the coefficient matrix of the variables in a process called Cramer's Rule. For 10 points, name this result which, for a 2 by 2 matrix, is found by subtracting the product of the numbers off the diagonal from the product of the numbers on the main diagonal.
