Desmos Scientific Calculator - Scientific calculator & functions

Explore mathematics beyond basic calculations with the Desmos scientific calculator! This tool not only allows for fundamental operations but also includes a wide range of built-in functions for delving into trigonometry, statistics, combinatorics, and more. You can even define and evaluate your own functions at no cost.

At Desmos, we envision a future where everyone has access to mathematical knowledge, making learning math both accessible and enjoyable for all students. To achieve this, we have developed a user-friendly yet powerful scientific calculator, powered by the same incredibly fast math engine as our advanced graphing calculator, but featuring a simplified set of tools for occasions when graphs are unnecessary. It's designed to be intuitive, visually appealing, and completely free to use.

Features:

Arithmetic: Beyond simple calculations, the scientific calculator also handles exponentiation, roots, absolute values, logarithmic functions, rounding, and percentages.

Trigonometry: Calculate key trigonometric functions and their inverses, utilizing either radians or degrees for angles.

Statistics: Determine the mean and standard deviation (for both sample and population) from a dataset.

Combinatorics: Count permutations and combinations, as well as perform factorial calculations.

Other attributes:

- Operates offline without needing an internet connection.

- Build and assess your own functions, using familiar notation.

- Assign values to variables for future reference.

- View multiple equations simultaneously. Unlike many scientific calculators, all prior calculations remain visible on the display.

- The “ans” feature retains the outcome of your last calculation, eliminating the need to memorize or jot down results. If you modify an earlier expression, the “ans” value updates accordingly.

- And remember, it's completely free!

About Desmos Studio

Desmos Studio is a Public Benefit Corporation with a goal of helping everyone learn math, love math, and grow with math. We believe that everyone has an inner mathematician and that some people haven’t been given the opportunity, encouragement, or tools to discover theirs. Learn more about our guiding principles.

Our free suite of math tools, including our Graphing Calculator, is used annually by over 75 million people around the world. Those tools help people represent their ideas mathematically, connect different representations dynamically, make conjectures, and then develop entirely new ideas. They also result in some pretty spectacular art.

We partner with the world's most popular curricula and learning software, and with the majority of U.S. state-level assessments and digital college entrance exams.

About Desmos Classroom

Desmos Classroom is now part of Amplify Education! Learn more.

Desmos Classroom invites, celebrates, and develops student brilliance through free digital classroom activities, thoughtfully designed by teachers for teachers. Those activities are guided by our pedagogical philosophy and help students to explore concepts deeply, collaborate with their peers on problem-solving, and apply knowledge creatively as mathematicians.

In 2020, we turned those experiences into a core middle school math program, combining a problem-based curriculum from Illustrative Mathematics, scalable support models from Amplify, and Desmos Classroom's intuitive technology and humanizing pedagogy.
