Description

Is your telephone number prime ? Or your Birthday ??
N2x3x5x7x will show the prime factors for any number up to 10,000,000,000. It will also convert any number from/to any base 2 to 16.
Use N2x3x5x7x, with its unique spiral keyboard, to explore the natural numbers and see if you can find primes, or perhaps a surreal pattern...
