Computing: Free Pascal Programming

Mathematics trainer: 3-by-3 linear systems.

Download Equations3 desktop application (Windows 64bit) Download Equations3 source code (Lazarus/Free Pascal)

Description: Generation of exercises concerning systems of linear equations in 3 variables. The application does exactly the same for three-by-three linear systems, what 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: radio groups, edit fields, (push) buttons with action depending on button's caption.
