Not exactly trivia, but maybe fun ;-)

Not exactly trivia, but maybe fun ;-)

This is just a little something for fun:

Do the following:

1) Pick a three or four digit number

2) rearrange the digits any way you like

3) Using the original number and the new one you created, subtract the smaller one from the larger.

4) Circle one of the numbers in the answer. Don't circle a zero because it is already a circle.

5) Post the remaining digits of your answer (other than the one you circled) in any order that you like.

I will tell you what number you circled. (I have to rely on your honesty to tell me if I am correct or not ;-)

Ok, now

tell me how it works. I know that Bill knows;-)

I can explain the answer, but one of these days, I will have to do the math proof to see the whole thing.
