Is there a rule for division by 11?
Yes there is. For big numbers it's usually harder to divide. So let's say you want to see if 346 is divisible by 11. First, you add up every other digit in the number.
3 + 6 = 9
4 + 0 = 4
Then you subtract the smaller answer from the bigger one.
9-4=5
If the answer you get is divisible by 11, then the whole number is. Therefore, 346 is not divisible by 11.
