I was bored at work today (it being Monday morning) and I started thinking about my badge number.
It's nine digits long and contains all nine digits from 1 to 9. Remarkably, the whole number is divisible by 9 (no remainders!). If you remove the last digit from the number, it is divisible by 8. If you remove the next number, it is divisible by 7. And so on... Right down to the last number, which is, of course, divisible by 1.
What's my badge number?
I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!
