Not only does the tutor perform the arithmetic of row operations for you, but it will also give you hints when solving a system of linear equations with the Gauss-Jordan method or when finding the inverse of a matrix with row operations. When you are stuck on such a problem, and not sure how to proceed, you can request a hint guiding you to the solution. The more hints you ask for the more guidance you will receive. Eventually, when using the Gauss-Jordan method or when you are finding a matrix inverse with row operations, the tutor will tell you a correct row operation to use. If the problem is not solvable the tutor will tell you so. This way the techniques are continually reinforced and soon you will not need to ask for hints.
If you want more than hints, turn on the solver from the settings view. Now step by step solutions for Gauss-Jordan or matrix inverse problems will be given.
