Odd. I'm guessing it's also a prime number.

It can't be NEVER ODD OR EVEN. (I like that palindrome. "Weird Al" Yankovic taught it to me.)

I like knowing that you can tell if a number's divisible by 3 if the digits in it add up to 3, and that numbers whose digits add up to 9 can be divided by 9. I think those are among the few math things I figured out on my own. (I even figured out part of the pattern in numbers divisible by 7, but always heeded the math textbooks' note that it was easier just to divide by 7 than to see if the number possibly fit that pattern... Huh. Who knew I had stuff to say about math?)

I think not only if they add up to 3, but if the sum of the numbers is a multiple of three as well.

It's odd...but who are we to judge? I'm sure its friends find it charmingly offbeat.
