Again stolen from the Star:
"You find a scrap of paper on the floor with the following addition
on it:
161
134
145
___
503
it looks wrong. . . but is perfectly correct. Why?"
Don't ask ME! I'll post answer in a week.

This addition adds three base 7 numbers, and obtains a sum in base 7. -- ========================================================================== Bob Parnass, AT&T Bell Laboratories - ihnp4!ihuxf!parnass - (312)979-5760

The answer to that is easy. If you do any computing, it makes you think in bases other thn decimal, which this problem is. if you add up the right column and subtract the 'answer' from it, you most likely have the base that is needed for the rest of the problem. Just to check, use that base to figure the other columns out. This problem comes out to be: 161 7 134 7 145 7 ---- 503 7 QED

Well, I recieved about 22 replies, and guess what?! - they were all
correct (except for one guy who said I was crazy!)- the answer is
that it's in base-7 (as if you didn't know).
