It's a multiple of 9 but there are still different symbols.
Only multiple of 9 between 9 and 81
(that is, 9,18,27,36,45,54,63,72,81)
would have the same symbol. Other multiple of 9 such as 90 or 99 don't need to be the same symbol because they will never be shown..... ;)
Reason:
The smallest possible answer is if you pick
10, which results in 10-1=9.
The largest possible answer is if you pick 99, which results in 99-18=81. |
