TI-30XS Calculator Online
The classic classroom scientific calculator, free in your browser. No download and no account needed.
What Is the TI-30XS Calculator?
The TI-30XS is Texas Instruments’ classroom scientific calculator. Schools choose it for its clear fraction display and simple layout.
This online version mirrors the real device. If you know the handheld, you already know this tool.
TI-30XS vs TI-84
The TI-30XS is a scientific calculator. The TI-84 is a graphing calculator. The TI-84 costs more and does more — graphing, matrices, and programming. The TI-30XS covers everyday classroom math at a lower price.
What Can You Do With the TI-30XS Calculator?
Fractions and Decimals
Enter fractions exactly as written. Toggle to decimals with one key.
Powers and Roots
Square numbers, cube numbers, or use any exponent. Take roots just as easily.
Trigonometry
Sine, cosine, and tangent with degree and radian modes.
Logarithms
Base-10 log and natural log. Solve exponential equations fast.
Scientific Notation
Enter large and small numbers cleanly. Read results in proper notation.
Statistics
One-variable statistics for classroom data sets. Find mean and standard deviation.
Probability
Factorials, permutations, and combinations. Great for probability units.
Function Tables
Generate tables of values for any expression. Spot patterns quickly.

TI-30XS Calculator Examples
Fractions
Enter 3/4 + 1/2. The answer is 5/4, or 1.25 as a decimal.
Square Roots
Enter √(81). The answer is 9.
Trigonometry
In degree mode, enter cos(60). The answer is 0.5.
Scientific Notation
Enter 6.02 × 10²³ ÷ 2. The calculator handles the exponent cleanly.
Statistics
Enter {2, 4, 4, 4, 5, 5, 7, 9}. The mean is 5.
Degrees and Radians on the TI-30XS
Look for the DEG/RAD indicator on the display. Switch modes before trig calculations.
Geometry problems usually want degrees. Higher math often wants radians. When answers look wrong, the mode is the first thing to check.
TI-30XS Calculator Features
Clear two-line display shows your entry and answer together. Fraction keys keep exact values. Memory keys store numbers for multi-step problems.
The layout matches the physical TI-30XS. Students can practice here and use the same keys on the real device.
Who Uses the TI-30XS Calculator?
Middle school and high school students use it most. Teachers recommend it because every student gets the same layout.
It suits general math, pre-algebra, algebra, geometry, and basic science. It is also common in standardized test prep where graphing calculators are not allowed.
