| Mathematical geniuses. There are only so many combinations. Unless of course you can't add.
For example 11 to 19.
11-(1+1)= 9.
12- (2+1) = 9
with 20 to 29
20 - (2+0) = 18
21 - (2+1) = 18
and so on. 30 to 39 gives 27. 40 to 49 gives 36. 50 to 59 gives 45 etc etc
And the symbol for 9 18 27 36 and 45 are always the same as each other.
