TI-84 Plus Calculator Online Free

This TI-84 Plus calculator online is a free, browser-based simulator built for students taking AP Calculus AB/BC, AP Statistics, Pre-Calculus, Algebra II, College Algebra and the SAT / ACT / PSAT. It mirrors the TI-84 Plus key layout (2nd, MODE, MathPrint, STAT, TABLE, STO→) so you can practice the same keystrokes you'll use on the physical calculator.

The TI-84 Plus is the most widely used graphing calculator in U.S. high schools and colleges. Whether you're working through homework, reviewing for a midterm or practicing for the SAT, this simulator gives you the scientific power of the TI-84 — 100% free, no download, no account.

Which TI-84 variants does this simulator cover?

The simulator follows the standard TI-84 Plus key layout shared by all of these models:

• TI-84 Plus — the original 2004 model, still widely used
• TI-84 Plus Silver Edition (SE) — extra RAM, Flash apps
• TI-84 Plus CE — color screen, rechargeable battery (the current US version)
• TI-84 Plus CE-T — exam-mode variant sold in Europe / UK / AU
• TI-84 Plus C Silver Edition — short-lived color model

Color graphing and TI-Basic side-loaded apps from the physical CE are not part of the browser simulator, but the scientific, statistics and table workflows are identical.

What can this online TI-84 calculator do?

• Scientific operations — powers, roots, absolute value, factorials, scientific notation
• Trigonometry — sin, cos, tan, sin⁻¹, cos⁻¹, tan⁻¹ in DEG / RAD / GRAD mode
• Logs & exponentials — ln, log, 10^x, e^x (second-function 10^ and e^ on the log and ln keys)
• Statistics — 1-Var and 2-Var stats: mean (x̄), σ, sample standard deviation (sx), Σx, Σx², min, max, median, Q1, Q3
• Table mode — type Y₁ = … and generate an x-y table just like TABLE on a real TI-84
• Memory STO→ / RCL — 7 named variables (x, y, z, t, a, b, c) for chained calculations
• Combinatorics — nPr and nCr accessible via the 2nd layer
• Order of operations — parentheses, implicit multiplication, and MathPrint rendering of fractions and exponents

TI-84 Plus vs TI-83 Plus: Should I care?

If you have a TI-83 Plus sitting at home, almost everything you do on this TI-84 online simulator translates directly. The TI-83 Plus shares the same keystroke menus and TI-Basic programming model. The TI-84 Plus adds a faster Z80 clock, more Flash memory, a built-in clock, USB port and — in newer OS versions — MathPrint natural display. Most TI-83 Plus programs run on a TI-84 Plus unchanged.

TI-84 Plus vs TI-30XS MultiView: which one do you need?

What tests allow the TI-84 Plus?

The physical TI-84 Plus is approved for the SAT, ACT, AP Calculus (AB/BC), AP Statistics, AP Physics, AP Chemistry, PSAT, IB Math, GRE Subject (Math), Praxis, and most U.S. state standardized tests. It is not allowed on the GED (which restricts you to the TI-30XS). Always check your specific exam's calculator policy before test day, and bring your physical TI-84 Plus — phones and online simulators are never allowed during the actual exam.

How to use this TI-84 online simulator

1. Type or click numbers and operators to build an expression.
2. Press 2nd (top-left) to access the green secondary labels above each key.
3. Press MODE to cycle DEG → RAD → GRAD. Trig answers depend on this mode.
4. Tap the CALC / STAT / TABLE tabs under the screen to switch into statistics or function-table mode.
5. Press ENTER to evaluate. The result is right-aligned at the bottom of the LCD.
6. Use STO→ followed by 1-7 to store the current answer into x, y, z, t, a, b or c.
7. Click the 📋 button to copy the result to your clipboard.
