Re: Little puzzle

When you add together the digits in a number and keep doing so until there is a single digit you eventually get the remainder of the original number divided by 9 (or 9 if the remainder is zero).  In the past this property was a way of checking sums and I myself occasionally use it when doing addition with pen and paper. Describing the technique is much more complicated than using it.
  23870        2+3+8=13, 1+3=4+7=11,1+1+0=2 (23870/9=2652 r 2)
+87745       8+7=15,1+5=6+7=13, 1+3+4+5=13,1+3=4 (87745/9=9749 r 4)
=111615    1+1+1+6+1=10,1+5=6 (111615/9= 12401 r 6)  which equals the sum of the remainders of the numbers being added (2+4)
It's the way I tell 'em. Shocked
Apologies to anyone who read this message when I first posted it. It originally contained errors which (hopefully!) I have now rectified. Embarrassed
