If a number is a multiple of nine, its digit root (the sum of its digits until the answer is only one digit long) is 9 (for multiples of 3, this is the case if the digital root is 3, 6 or 9).
For 163, 1 + 6 + 3 = 10. 1 + 0 = 1 so the digital root is 1 and therefore 163 is not a multiple of 9.
However, for 162, 1 + 6 + 2 = 9 so the digital root is 9 so 162 is a multiple of 9 (18 x 9 = 162).
Negative 162 is bigger.

An infinite number, starting with these: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198 . . .
It signifies the number nine or multiples of nine: nothing more, nothing less.It signifies the number nine or multiples of nine: nothing more, nothing less.It signifies the number nine or multiples of nine: nothing more, nothing less.It signifies the number nine or multiples of nine: nothing more, nothing less.
The multiples of nine are numbers that can be divided evenly by nine. To find the multiples of nine up to 200, you would simply continue multiplying nine by whole numbers until the result exceeds 200. The multiples of nine up to 200 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, and 198.
