What Is the Desmos Scientific Calculator?
The calculator on this page is Desmos's own free, official Scientific Calculator, embedded directly here. Desmos Studio is the company behind it, and the same tool is used in classrooms and on state math assessments across the US (North Carolina and Virginia, among others, use Desmos calculators in their official testing programs). No login, download, or account is required to use the embedded version above.
What You Can Calculate With It
- Basic arithmetic: addition, subtraction, multiplication, division, and percentages.
- Powers and roots: squares, higher powers, square roots, and nth roots.
- Fractions: enter and simplify fractions directly, without converting to decimals first.
- Trigonometry: sin, cos, and tan, with a toggle between radians (RAD) and degrees (DEG).
- Absolute value and pi (π): both available as one-tap buttons.
- Previous answer (ans): reuse your last result in a new calculation without retyping it.
Frequently Asked Questions
What's the difference between the Desmos scientific calculator and the Desmos graphing calculator?
The scientific calculator (embedded above) handles arithmetic, trigonometry, roots, and similar one-off calculations. The graphing calculator is a separate Desmos tool for plotting functions, visualizing equations, and working with sliders and animations. They're built for different tasks.
Does the Desmos scientific calculator handle matrices?
No. Matrix operations are a separate Desmos tool, the Matrix Calculator, where you can build a matrix and run operations like addition, multiplication, and finding an inverse or determinant. The scientific calculator above is built for everyday arithmetic and trig, not matrix work.
Can I download the Desmos scientific calculator for PC?
The calculator above runs directly in your browser, so there's nothing to install on a PC or Mac. Desmos also publishes official scientific calculator apps for Android and iOS if you want an offline mobile option.
What is the "Desmos Scientific Calculator NC" version?
That's North Carolina's official state-testing version of the Desmos scientific calculator, used for middle school math assessments (grades 6-8) and NC Check-Ins. It's a restricted version of the same tool: it doesn't allow custom function definitions and uses an alphabetical keypad instead of the standard layout, matching what students see during the actual test.
