TI-84 Calculator OnlineA TI-84 Plus CE simulator that works like the real thing
Press the same keys you would on the handheld: 2nd and ALPHA menus, Y= graphing with TRACE and CALC, the STAT list editor with regressions, and the DISTR probability functions. Type on your keyboard, and your work is saved in your browser.
TI-84 Plus CEOnline simulator
Type a calculation and press ENTER.
Y= enters a function · GRAPH draws it

What it can do
Built for real classwork, not just arithmetic
Every button below loads an example straight into the calculator above, so you can watch the keystrokes play out.
Y= and CALC
Graphing that traces
Enter functions in Y=, then use TRACE and the CALC tools for zeros, minimums and intersections. See the graphing guide.
STAT lists
Statistics from real lists
Type data into L1, then run 1-Var Stats or a regression. See the standard deviation guide.
DISTR menu
Probability distributions
normalcdf, invNorm, invT, binompdf and more from 2nd + VARS, with the same syntax as the handheld.
How to use it
Three ways students use this TI-84 calculator online
Learn the keystrokes
Follow a guide with the calculator open beside it. Menu paths like 2nd + + → 7 → 1 → 2 work exactly as written, so the muscle memory transfers to the handheld you use in class.
Check homework fast
Graph a function, press 2nd + TRACE and read the zero or intersection, or run a regression on your list data and compare it with your working.
Type instead of clicking
Your keyboard drives the calculator, which is much faster for long expressions.

Task calculators
Answer one question quickly
Focused tools built on the same engine as the simulator, so the answers match what the handheld prints — and each one shows the keystrokes or syntax to reproduce it yourself.
Quadratic equation solver
Exact roots, the discriminant, the vertex and the working
Gives surds such as (3+√5)/2 rather than rounding to a decimal
Matrix calculator
rref, inverse, determinant, multiply and transpose
Reports the handheld's own errors, such as SINGULAR MAT
Standard deviation calculator
Sx, σx, the mean and the five-number summary
Makes the sample and population choice explicit
normalcdf and invNorm calculator
Normal areas, percentile values and the z-scores behind them
Shows the exact syntax to type into DISTR
Linear regression calculator
Line of best fit with r, r² and a prediction for any x
Explains why r and r² are missing until diagnostics are on

Honest limits
What is simulated, and what isn’t
A calculator you can’t trust is worse than none. Here is exactly where this one matches the handheld and where it stops — anything missing says so on screen instead of inventing an answer.
✅ Works like the handheld
- 2nd and ALPHA layers, and the menu paths in our guides
- Y= graphing, ZOOM presets, TRACE, TABLE and the CALC tools
- STAT list editor, 1-Var/2-Var stats and seven regressions
- DISTR: normal, t, χ², F, binomial, Poisson, geometric
- Order of operations, fractions, MEM reset and error messages
⛔ Not simulated yet
- Stacked MathPrint templates (entry is linear, like Classic mode)
- Stat plots such as scatter and box plots
- TI-BASIC programs, apps and games
- Complex numbers (results are REAL mode only)
- Linking to another calculator, and Press-to-Test
📝 Before an exam
Exam boards require a physical, approved calculator. Use this to learn the keystrokes and check homework, then practise on the handheld itself. See how to reset memory before a test.
FAQ
Frequently asked questions
Yes. There is no account, subscription or download. Everything runs in your browser, so it also works on school Chromebooks, iPads, Macs and Windows laptops.
Yes. Digits, ., +, -, *, /, ^, parentheses and commas all work. Enter evaluates, Backspace is DEL, Esc is CLEAR, the arrow keys move the cursor and X types the X variable. Typing a letter enters that letter, so you can type sin( or L1 directly.
Yes. Your history, Y= equations, window settings and stat lists are saved in your own browser storage. Nothing is uploaded, and 2nd + + → 7:Reset clears everything just like the handheld.
The maths engine, menus, graphing, statistics, matrices and distributions behave like the handheld, and the keystrokes in our guides match. Not simulated yet: stacked MathPrint templates, the matrix EDIT grid, TI-BASIC programs, apps, stat plots and complex (a+bi) results. Everything that is missing says so on screen instead of guessing an answer.
Work out the answer, then press MATH and choose '1: ▶Frac' and ENTER. It also works on a whole expression: type 3/4+2/5, then MATH 1 and ENTER to get 23/20. See our fractions guide.
Exponents are applied before the negative sign, so -5² means -(5²) = -25. To square a negative number use parentheses: (-5)² = 25. Use the (-) key for negatives and the - key for subtraction.
- is subtraction between two numbers (8 - 3). (-) next to ENTER makes a number negative (-5). Pressing - at the start of an empty line inserts 'Ans-' instead, which is why it looks wrong.
The calculator is in radian mode, so it reads 30 radians. Press MODE, highlight DEGREE and press ENTER. The angle mode is always shown in the status bar at the top of the screen. You can also type 30° using 2nd + APPS (ANGLE).
Press GRAPH, then 2nd + TRACE to open CALC. Choose '2: zero', '3: minimum', '4: maximum' or '5: intersect' and answer the Left Bound, Right Bound and Guess prompts with the arrow keys or by typing an x value. Full walkthrough in our graphing guide.
Press STAT and choose '1: Edit…', type your values into L1, then press 2nd + MODE to quit, STAT, arrow to CALC and choose '1: 1-Var Stats'. Read x̄ for the mean, Sx for sample standard deviation and σx for population. See the 1-Var Stats guide.
Press 2nd + VARS for the DISTR menu. It includes normalpdf, normalcdf, invNorm, invT, tpdf, tcdf, χ² and F functions, plus binomial, Poisson and geometric distributions. Syntax matches the handheld, for example normalcdf(-1.96,1.96).
Usually the window doesn't match the curve: press ZOOM and choose '6: ZStandard' to return to -10 to 10, or '0: ZoomFit' to fit the y range. Also check in Y= that the '=' sign is highlighted — press ENTER on it to switch a function back on.
Xmin must be smaller than Xmax and Ymin smaller than Ymax. Press WINDOW and fix the values, or press ZOOM '6: ZStandard' to reset them.
Pressing DEL on the L1 heading removes the column from the editor. Press STAT and choose '5: SetUpEditor', then ENTER; reopen STAT '1: Edit…' and L1 to L6 are back with their data.
CLEAR once clears the line you are typing; press it again to clear the screen (press the up arrow to scroll back through earlier work). To erase everything, press 2nd + + for MEM, choose '7: Reset…', then '1: All RAM' and '2: Reset'. Our reset guide covers the handheld too.
That usually means a deeply discharged battery. Charge it from a standard 5V phone-style charger for 20-30 minutes, then press the small recessed reset button on the back for a couple of seconds. Details in our power and battery guide.
No. Exam boards require a physical, approved calculator and do not allow laptops, phones or browsers in the exam room. Use this to learn the keystrokes and check homework, then practise on the handheld before test day.
The TI-84 Plus and TI-84 Plus CE are accepted on the SAT, PSAT, ACT and AP exams because they have no computer algebra system or QWERTY keyboard. IB requires an approved model placed in exam mode, and the approved list changes — check your exam board's current list before test day. CAS models such as the TI-89 are not allowed on the ACT.
The TI-84 Plus CE simulator on this page and the full-screen graphing calculator are the finished tools. There are also beta versions of the TI-30XS MultiView, TI-83 Plus and TI-89 Titanium that are still being built out.
