Maths trainer: 3-by-3 linear systems (Equations3).


Description: Generation of exercises concerning systems of linear equations in 3 variables.The application does exactly the same for three-by-three linear systems that Equations2 does for two-by-two systems. If there is a unique solution to the equation, just enter the values for x, y and z; if there are no or an infinity of solutions, check the corresponding radio button.
Use the "Start" button to begin the test; push "Solve" to check your answer, "Next" for the next exercise. If the chosen number of exercises have been done, push "Evaluation" to display your success percentage. Use "Restart" to do another test.

Free Pascal features: Basic and extended controls: radiogroups, edit fields, (push) buttons with action depending on button's caption.
