Directly on your graphing calculator.

Discover the first Python app on a calculator : an industry standard programming language you can use in class.

**Fractions, roots, trigonometry…**

Your calculator embeds an advanced math engine that can accurately compute most math expressions.

**Take the SAT and the ACT.**

The NumWorks graphing calculator is approved for use on the PSAT*, SAT* and ACT college entrance exams.

* Starting with the August 2018 administration.

**No registration, no installation.**

You can freely use the NumWorks graphing calculator emulator on your computer, your tablet or your smartphone.

Try it in your browserTrace colored graphs using the Functions app, read function values in a table and retrieve the derivatives.

Pick your law (binomial, uniform, exponential, normal or Poisson), fix your parameters and compute your probabilities as well as their inverse on a given interval. A graphical display helps you visualize your computations.

Solve your equations and linear systems. This app computes the discriminant and exact roots of quadratic equations and gives exact solutions of linear systems.

The Calculation app can work with matrices. Compute powers, determinants and inverses.

Sequences are defined just like in a textbook. Compute the sum of terms directly on the graph.

After entering your data, you can visualize the regression line and its equation directly on the graph.

Easily access the statistics computed on your data and identify key results at once.

You can both visualize your data and look up the values on the same screen.
