Numbermatics - the number explorer

Curious what makes numbers tick? Numbermatics reveals everything you could want to know about the integers.

Discover the secrets of prime numbers and composites and peek into the hidden structure of numbers from one to (almost!) infinity.

Numbermatics includes a wide range of mathematical data and numerical statistics, plus trivia, fascinating facts and other useful info. We hope our experimental graphics and visualizations help users explore and understand how numbers are put together. With our number link buttons you can even use this site as a primitive calculator or prime number explorer.

We are currently serving data on around 9.0 x 1019 integers. That's over a quintillion numbers! We hope to bring you more numbers soon.

As a school-friendly resource, we hope the Numbermatics project will be a useful addition to educational and STEM contexts. Suitable for students studying a curriculum at school, in college, taking exams, at university, on a course or STEM (Science, Technology, Engineering and Math) contexts.

To start your journey, enter a number in the box above or jump to a random number. We can also recommend the number 42.

The information we have on file includes mathematical data and numerical statistics calculated using standard algorithms and methods. We are adding more all the time.
