I think i figured it out. but not sure if i am right.
ok .
for all prime numbers it is 0;
for all non prime numbers it is
it is (#of prime decomposition terms -1 *2);
i know it sounds complicated..but for example:
4 = 2*2;
so two terms.
2-1 = 1; 1+1 =2;
8 = 2*2*2 ;
so now three terms.
3-1 =2; 2+2 = 4;
9 = 3*3;
so two terms.
2-1 = 1; 1+1 = 2.
so then 10 + 10 would be..
10 = 2*5
so two terms.
so 10+10 = 2.
is this right??

Think KINDI.
When I was a kid I coloured in the enclosed areas of numbers and letters.
The sums are a simple count of the number of enclosed areas to colour in.
eg
1+1 = 0 (there are no areas to colour in)
2+2 = 0 (again nothing)
3+3 = 0
4+4 = 2 (look 2 triangles to colour in)
5+5 = 0
6+6 = 2
7+7 = 0
8+8 = 4 (the number 8 has 2 enclosed reagions each making 4)
9+9 = 2
10+10 = 2 (the two 0 reagions)
That's what I think anyway....
