How to judge whether a number is a multiple of 1 1 in number theory?
The difference between the sum of odd digits and the sum of even digits of a number is a multiple of 1 1, so this number can be divisible by 1 1.

For example: 95863 1 102.

9+8+3+ 1+2=23

5+6+ 1+0= 12

23- 12= 1 1 is a multiple of 1 1.

So 95863 1 102 can be divisible by 1 1.
