If you haven't figured it out, here is my godson's answer. I just have to assume he's right because he is right about everything.

It uses the same symbol for all the possible numbers eg


0,9,18,27 ......


since you must take some number z = xy - (x+y) only a subset of numbers are possible. take the numbers in the 90's for instance


99 -> 99 - (9+9) = 81
98 -> 98 - (9+8) = 81
97 -> 97 - (9+7) = 81
.
.
.
.


See every time you subtract 1 from your starting number (xy_new) you also subtract one from your second number (x+y_new). since y_new = y-1.
