The Online Enclopedia of Calculations

Number Reference is an open source project to computationally compile an encyclopedia of calculations with an emphasis on:

  • Accessibility
  • Discoverability
  • Accuracy


Our vision is to provide and explain computations for as many possible integers as possible.

To fulfill the project's primary objective of accessibility, the project's content is available for free, non-commercial on the world wide web and all textual explanations will be translated across languages.

The Logo

The logo is the symbol of infinity and serves as a humble reminder that there are always more numbers.
