Efficient Algorithms for Zeckendorf Arithmetic
Article by Ahlbach, Connor and Usatine, Jeremy and Pippenger, Nicholas
In collection: Easily explained
We study the problem of addition and subtraction using the Zeckendorf representation of integers. We show that both operations can be performed in linear time; in fact they can be performed by combinational...

I wonder if some crazy mathematician ever thought of talking to a number as if it was a friend... (Because numbers are friends?)

Genuinely assumed this was about Prince William and really couldn't work out what the banks could possibly be doing.
