Sharing and transparency

We believe in education and collective intelligence so we're providing you with all our know-how to invite you to be part of the first collaborative calculator.

A collaborative project

NumWorks is the first open graphing calculator: all our engineering effort is made available online under a Creative Commons license.

Each device can be completely customized, and the community can build improvements that will be collectively shared in software updates.

All our blueprints and 3D plans are public. Devices can be easily repaired, and using some off-the-shelf electronic components you can even try to build your own 3D printed calculator.
