OK then.

 

First, if you add together the two digits of a two-digit number and take it off the number you first though of, you always get a multiple of nine. [This is because a 2-digit number is 10x plus y , so if you take off x+y, you get 9x -- but anyhow, trust me on this or try it out.]

 

All the multiples of 9 in the chart have the same symbol!

 

The clever bit is that the symbol changes each time you try -- but all the 9-times still have the same symbol as each other.
