Our calculator's interface matches the real calculator, so students can practice before exams, learn menu navigation, understand graphing functions, and complete assignments faster.
The calculator looks and behaves exactly like a TI-84 Plus, making it easy for students and teachers to switch between real and online versions.
No installation needed to do calculations.
Always up and available for users.
Handles all levels of math and statistics calculations.
Great for algebra, geometry, calculus, physics, chemistry, and engineering.
Simple enough for beginners and powerful enough for advanced users.
Yes — every calculator on this site is 100% free to use. No signup, no download, no time limits, and no premium version.
No. All calculators run directly in your web browser on phones, tablets, laptops, and desktops.
The emulator recreates the TI-84 Plus CE interface, buttons, and menus so you can practice exactly as you would on the physical device. Learn more on our TI-84 calculator page.
Visit our TI calculator blog for step-by-step tutorials on graphing, statistics, matrices, probability, and more.
Yes. You can enter several functions in the Y= menu (Y1, Y2, Y3, etc.). When you press GRAPH, the calculator will display all of them on the same coordinate plane. This is especially useful for comparing equations, analyzing intersections, and visualizing relationships between functions.
Absolutely. The STAT menu works exactly like the physical TI84. You can enter lists, run one-variable or two-variable stats, and perform regressions such as linear, quadratic, exponential, and power regression. The results are identical to a real TI-84 Plus.
Some browser versions allow you to right-click and save the canvas or take a screenshot. While the emulator itself does not have a built-in “save graph” button, you can easily capture your graph using your device’s screenshot tool.
Yes. The TABLE and TBLSET functions work exactly like on the real calculator. You can set the starting value, the increment, and view x- and y-values for any function entered in the Y= menu. This is very helpful for homework and function analysis.
Yes. You can switch between Degree and Radian modes in the MODE menu. Trigonometric functions will then calculate results according to the mode you selected.
Yes. The MATRIX menu supports creating, editing, and performing all of these matrix operations.
Yes. It allows solving linear, quadratic, polynomial, and trigonometric equations. You can use:
The Equation Solver is under the MATH menu.
Graph → CALC → Intersect for roots.
Numeric solve methods via custom expressions.
While the TI-84 doesn’t support an official “piecewise” input, you can graph functions piecewise by entering multiple conditions using the inequality and logic features. The online version supports this the same way the physical calculator does.
Yes. The STO→ key works normally. You can store values to variables (A, B, C, etc.) and recall them whenever needed, just like on a real TI-84 Plus.
Yes. Under MATH ⇒ PRB, you can use:
nPr
nCr
! (factorial)
random integers
random decimals
Yes, our online TI-84 emulator supports MathPrint formatting for fractions, exponents, roots, logs, summations, and integrals.
Yes. The calculator supports:
Numerical derivative (nderiv)
Numerical integral (fnInt)
These tools work under the MATH menu and operate just like the physical one.
No. Online calculators are usually not permitted during official exams. You can use it for studying, practicing menus, learning TI-84 navigation before the exam, and completing homework efficiently.
Yes. You can enter data into L1, L2, L3, etc., and generate scatter plots, histograms, box plots, and regression equations. All list-based graphing tools are available in our tool.
Most online TI-84 tools include a “reset” or “reload” option. If something becomes unresponsive, simply refresh the browser tab. The calculator reloads instantly with default settings.
Open the free TI-84 emulator and follow our complete manual to master every feature.
