An intuitive and powerful suite of free digital math tools, including a best-in-class graphing calculator, designed to help students and teachers visualize and explore mathematical concepts interactively.

Try it out

Desmos provides a collection of sophisticated yet accessible web-based math tools centered around its renowned graphing calculator. It empowers students from middle school to college and their teachers to visualize mathematical concepts, from simple equations to complex calculus problems, through dynamic and interactive graphs. The platform's unique value lies in making abstract mathematical ideas tangible and explorable, which fosters a deeper, more intuitive understanding. Beyond graphing, Desmos offers scientific and four-function calculators, as well as a geometry tool, all available entirely for free. This strict emphasis on accessibility and powerful visualization has made it an indispensable resource in modern math education.

Pros

  • The user interface is exceptionally intuitive, allowing for immediate graphing with a minimal learning curve.
  • Completely free core tools, including the graphing, scientific, and geometry calculators, removing all cost barriers.
  • Dynamic sliders allow for real-time exploration of how changing variables and parameters affects graphs.
  • Powerful graphing capabilities, supporting parametric, polar, and piecewise functions, inequalities, and calculus operations.
  • Web-based and cross-platform, working seamlessly on any modern browser across desktops, tablets, and smartphones.
  • Easy sharing and collaboration features allow users to save and send their work via a simple link.

Cons

  • Requires a consistent internet connection, as there is no official, full-featured offline desktop application.
  • While a 3D calculator exists, its features are not as robust or developed as the 2D calculator or specialized 3D software.
  • Lacks a Computer Algebra System (CAS), meaning it cannot perform symbolic manipulation like simplifying algebraic expressions.
  • Primarily a visualization tool, not a heavy-duty computational environment for complex programming or numerical analysis like MATLAB.

Key features

  • Interactive 2D function graphing (explicit, implicit, polar, parametric)
  • Sliders for animating and exploring graph parameters
  • Data tables and statistical regressions
  • Calculus tools for visualizing derivatives and definite integrals
  • Interactive geometry tool for constructions and transformations
  • Scientific and Four-Function calculators
  • Ability to save, share, and embed graphs
  • Accessibility features including screen reader support and high-contrast mode

Frequently Asked Questions

Top Alternatives to Desmos

GeoGebra

Choose GeoGebra for its integrated suite that combines graphing with dynamic geometry, spreadsheets, and a more powerful Computer Algebra System (CAS) for symbolic calculations.

WolframAlpha

WolframAlpha is superior for users who need a computational knowledge engine to solve complex equations symbolically and get step-by-step solutions, rather than just visualizing them.

Symbolab

Symbolab is a better choice if your primary goal is to get detailed, step-by-step solutions to a wide range of math problems, acting more as a problem-solver than a creative exploration tool.
