Scientific Calculator

All the computational power of our graphing calculator, just without the graph -- welcome to the Desmos Scientific Calculator!

The main keyboard of our Desmos Scientific Calculator displays the numerical keypad, basic operations, and functionality for basic trigonometry, roots, fractions, exponents, and absolute value.

Our full Qwerty keyboard features punctuation and a pi character. You can also access more advanced trigonometric and statistical functions using our function keyboard.

In the Settings Menu of the Scientific calculator you can toggle on Complex Mode.

This adds the imaginary number 𝑖 to the keypad and switches all angles to radians.

In Complex Mode, you’ll also have access to the functions real( ), imag( ), conj( ), arg( ), and \(| |\) (for modulus).

Many of the functions on our three different keyboards also have shortcuts available. Type ans to use the previous result in a new expression. Use forward slash (or division) to enter a fraction. Try sqrt for square roots and nthroot for cube roots and more! You can also instantly convert decimal answers into fractions.

We have support for Braille in both UEB and Nemeth, as well as a reverse contrast mode to help visual accessibility. Click the wrench icon to access these features.
