They also add up to a multiple of 9.
If the digital sum of a number does not add up to 9 then it is not a multiple of 9 as for example 153 is a multiple of 9 because 1+5+3 = 9
So there is a rule about multiples of 9 in general: something is a multiple of 9 if and only if its digits add up to a multiple of 9. 6+4 = 10, so it is not a multiple of 9. There's also a neat trick to remembering the multiples of 9 below 99 with your fingers, but you can look this up if you're interested.
No. Numbers divisible by 9 have digits that add up to a multiple of 9. 2+3+6=11, which is not a multiple of 9.
That they add up to 9
