i fixed it.
my bad.
i dont know what to say about that, im that that good at math.
use constructive counting and just have patience and try, that's how i do it.
is it 100, it is posted like this: $10#$10, thats like 10 or something!
There are 45 ways. There is a formula for it, if you want to know, please ask me.
i got the same answer as mathproblem solver101 9z(z^2-3z+3)
thanks melody!
