About & Credits
This website is an independent educational calculator page built to help students practice graphing, algebra, statistics, matrices, fractions and scientific calculations in a browser.
Calculator runtime credit
The interactive calculator is loaded from publicly accessible TestNav calculator runtime files. This website does not host those emulator runtime files and does not claim ownership of them.
Open-source wrapper credit
The page structure was inspired by open-source browser wrapper examples for the TI-84 Plus CE HTML5 calculator, including the public GitHub project ading2210/ti84pce-html5. Any reused wrapper logic should keep the original license notice where applicable.
