What is the other option to do division of 11?

Answer 1

Hello!!
If the difference of sum of odd and even numbers should be "0" or "11"

Answer 2

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2-7+2-8 = -11. Since -11 is divisible by 11, so is 2728.
