If a number is divisible by eleven the difference between the sum of the digits in the even places and the sum of the digits in the odd places is 11 or 0.
EXAMPLE.
23485 is shown to be divisible by 11 because2 + 4 + 5 = 11
3 + 8 = 11
11 - 11 = 0
and
and 60852 is shown to be divisible by 11 because
6 + 8 + 2 = 16
0 + 5 = 5
16 - 5 = 11
