interface is attractive and easy to use
Using JavaScript, it generates a random nonsingular 3-by-3 linear system. The corresponidng augmented matrix is populated from the system, and the user is directed to apply Gauss-Jordan elimination to find the unique solution. The appication provides a means for the user to apply each of the three elementary row operations after providing the appropriate coefficients. The interface is attractive and easy to use.
Students cannot enter their own problem
Easy to use and enter data for row operations. Students cannot enter their own problem. There is a"glitch"; the list of operations is not cleared when a new problem is initiated.
