If the rules for 2 and 3 work, the number is divisibale by 5.
add all the digits together and see if it is divisible by nine.

There is no divisibility rule for 13 because it is a prime number. If you are thinking: why is there a divsibility rule for 2 and 3 then. Well, i don't know so go look it up on google.
Just carry out the division.
By tautology. If it did not work, it would not be a divisibility rule!
The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.
The number must be divisible by 13 and by 11.
if the difference of the sum at the alternate places is divisible by 11 then it is divisible by 11
If the rules for 2 and 3 work, the number is divisibale by 5.
What is the divisblity rule by 8
There is no easy rule for divisibility by 34.
add all the digits together and see if it is divisible by nine.
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
