Coverage upgraded from the uploaded guidebook structure
The docs now cover the official guidebook-style learning path: key features, keyboard, home screen, menus, modes, expressions, graphs, tables, matrices, probability/statistics, variables, equation solving, apps, test-mode concepts and errors. The website pages are original summaries and workflows, not copied manual text.

Documentation FAQ
Is this an official TI manual?
No. This is original educational documentation for this independent website. It is not an official Texas Instruments manual.
Why use the guidebook structure?
The guidebook structure shows what users expect to learn: keyboard, menus, modes, expressions, graphing, statistics, matrices, variables and troubleshooting. Our pages explain those topics in original, web-friendly language.
Why create many docs pages?
Detailed documentation improves user value and gives Google stronger topical coverage beyond one calculator page.
