### The Constant of Kaprekar

**Date:** September 13, 2024

**Speaker:** Jeff Rushall (NAU)

**Abstract:** The constant of Kaprekar is a weird and magical number that pops up that when one rearranges the digits in almost any 4-digit number and then does some arithmetic. All who come to FAMUS will verify with their own 4-digit numbers that the constant is indeed magical. I’ll say a bit more and try to leave the audience as amazed and bewildered about the constant as I am.

The faculty guest is Sarah Watson. [PDF of Flyer]
