Nine has special significance for an accountant. And it has nothing to do with lives.
When you add a column of numbers twice and subtract their sums, if they are off by a factor of nine it means you have a transposition error. I think that is amazing.
It would always make me pause and reflect each time I found it to be so. And apparently, I have a touch of dyslexia because I found it to be true often. Or maybe I was subconsiously finding ways to test the theory. Try it for yourself. 96-69 = 27, divisible by 9.
