Solve Equations In New Ways

Equations can be rather scary, but these apps help you find the solution in all new ways.


Point, scan, and solve equations easily


Scan and solve

For those who want a fast and thorough way to solve equations on their homework assignments.

Photomath is a smart calculator app that does something unique and special, and is an invaluable tool for students. Just launch the app, point your camera at your equation, scan it, and Photomath will come up with the answer. But that's not all — rather than just give you an answer without showing you how it arrives to that solution, you'll get detailed step-by-step explanations of how to arrive at that answer. At the moment, Photomath has full support for arithmetics, fractions, decimal numbers, linear equations, equation systems, and some functions like logarithms. While you can have Photomath solve more complex problems like integrals, trigonometry, and derivatives, these don't have support for step-by-step explanations just yet.

Why we love it

We remember how tough equations can be in school, and wish we had something like this around back then. Being able to take a photo of the equation and then have it explain how to get the answer is super helpful.

Quick Graph+

Quick Graph+

KZ Labs

"The app you need to survive the next semester"
-- Gizmodo

Quick Graph+ is the best graphing calculator available on the AppStore!

Top 10 Education app in over 100 countries!
Featured on the App Store in more than 130 countries.

It is a powerful, high quality, graphic calculator that takes full advantage of the multitouch display and the powerful graphic capabilities of the iPad and iPhone, both in 2D and 3D.

"It's ok to write yet another graphing app, so long as it is the best one. And this is"
-- Review by RightyC1

It features a simple, yet intuitive interface that makes it easy to enter and/or edit equations and visualize them in mathematical notation. It's also capable of displaying explicit and implicit equations as well as inequalities in both 2D and 3D, in all standard coordinate systems: cartesian, polar, spherical and cylindrical, all with amazing speed and beautiful results, which can be copied, emailed or saved to the photo library. It also includes an evaluate feature, in order to evaluate equations at specific points, as well as a library where you can store commonly used equations.

Quick Graph+ differs from the free Quick Graph in that it already includes the advanced feature set which gives you access to all the features, such as implicit graphs and tracing. Keep in mind that for explicit graphs, you need to specify the dependent variable, since just typing "x^2" without the y=, will assume the expression to be "x^2=0" and it will be displayed as an implicit graph.

- VGA Output.
- 2D - 3D equation plotting.
- Library for commonly used equations.
- Wireframe and solid visualization.
