Exact keystrokes for the jobs students actually need: resetting memory before a test, graphing a function, running 1-Var Stats, fixing errors and getting out of Press-to-Test. Every guide works with the simulator on the home page.
The complete TI-84 guide is the one to read first — it covers arithmetic, fractions, graphing, statistics and the menus in one place. After that, most students need one of three things:
Master Guide
Master your TI-84 Plus or CE from scratch: basic arithmetic, stacked fractions, powers, trig angle modes, graphing Y=, 1-Var stats, regression and quick reference cheat sheet.
Troubleshooting
Clear memory, fix frozen screens, or prepare your TI-84 Plus / CE for SAT, ACT and AP exams with this step-by-step reset guide.
Troubleshooting
Quick methods to clear your home screen, purge calculation history and delete stored variables on TI-84 Plus & CE.
Graphing
Master the Y= editor, plot single or multiple functions, set appropriate Window boundaries and use Zoom presets.
Statistics
Enter list data into L1, run 1-Variable Statistics and read mean (x̄), sample standard deviation (Sx) and population standard deviation (σx).
Algebra
Use MathPrint fraction templates (n/d), convert between fractions and decimals (▶Frac / ▶Dec) and simplify improper fractions.
Hardware
Proper key sequence to power down your TI-84, save battery life and troubleshoot calculators that refuse to shut down.
Hardware
Which games run on a TI-84 Plus CE, what each one needs, and how to get them onto the calculator — including what changed in OS 5.5 and how to work around it.
Hardware
Side-by-side comparison of screen quality, processing speed, rechargeable battery, exam approval and pricing.
Troubleshooting
Turn off the flashing exam LED, restore locked programs and safely exit Press-to-Test mode using TI Connect CE or a calculator-to-calculator cable.
