Desmos Scientific Calculator

Move beyond arithmetic with the Desmos scientific calculator! In addition to the basic operations, take advantage of a variety of built-in functions for exploring trigonometry, statistics, combinatorics, and more.
Or, define and evaluate your own functions -- all for free.

At Desmos, we imagine a world of universal math literacy where math is accessible and enjoyable for all students.
To that end, weve built a simple yet powerful scientific calculator that runs on the same blazingly fast math engine as our next-generation graphing calculator, but with a more streamlined set of features, for those times when you just dont need a graph.
Its intuitive, beautiful, and completely free.

Features:

Arithmetic: In addition to the basic operations, the scientific calculator also supports exponentiation, radicals, absolute value, logarithms, rounding, and percentages.

Trigonometry: Evaluate the fundamental trigonometric functions and their inverses, using either radians or degrees for angle measure.

Statistics: Compute the mean and standard deviation (sample or population) of a list of data.

Combinatorics: Count combinations and permutations and calculate factorials.

Other features:

- Works offline, no internet connection required.

- Create and evaluate your own functions using familiar function notation.

- Assign values to variables for later use.

- View multiple expressions at once.
Unlike many scientific calculators, all of your previous work remains visible on the screen.

- The ans key always holds the value of your last computation so that you never have to remember or copy a result.
If you change an earlier expression, the ans value updates automatically.

- Did we mention its free?,
