TI-30XS Calculator Online
The simple scientific calculator, minus the pocket.
A free TI-30XS style emulator for quick homework math. Trig, logs, roots, and powers on one clean keypad — nothing to install, works on your phone.
Try: sin(30) or 2+2*3
Click the calculator, then type on your keyboard — digits, + − * / ^ ( ) work, Enter calculates.
Why the TI-30XS style works
The TI-30XS MultiView is the calculator most students meet first. It is not a graphing calculator — it is a straightforward scientific calculator, and that simplicity is the point. Fewer menus means fewer mistakes.
Our online version keeps that spirit. Every function sits on the main keypad: sine, cosine, tangent, both logarithms, square and cube roots, and powers. You never hunt through a second-function menu.
Good for these classes
Middle school math: fractions-style arithmetic, percents, and basic exponents. Everything here is one tap away.
Algebra and geometry: square roots, the Pythagorean theorem, and SOH-CAH-TOA trig. Just remember to set DEG mode for geometry.
Chemistry and physics: scientific notation, logarithms for pH, and quick unit-conversion arithmetic. The history panel is handy when a problem has five steps.
TI-30XS vs TI-84: which do you need?
Think of it this way. The TI-30XS style is a fast, simple tool for calculations you could almost do by hand. The TI-84 is a full workstation with graphing, statistics, and programming.
For daily homework in algebra or geometry, this page is usually enough — and faster. When your teacher says "graph it" or "run a regression," hop over to our graphing calculator or the full TI-84 emulator.
Tips for fewer wrong answers
Close your parentheses. A missing ) is the most common reason a TI-style calculator gives a weird answer. Get in the habit of typing the closing parenthesis every time.
And double-check DEG vs RAD before trig. Geometry homework wants DEG. If your answers are off by a lot, that toggle is almost always the culprit.
