Divisibility by 11
Shqip
A number is divisible by 11, if the difference between sum of odds digits and sum of even digits is
0 or a multiple of 11.
For example:
34871903 (The number)
3+8+1+0=12 (sum of odd digits)
4+7+9+3=23 (sum of even digits)
23-12=11 (the difference)
The number is divisible by 11.
