That was really fun to do. Ignore the self-appointed critic down there. He has to find fault with everything. =) The rest of us liked it a lot!

Definitely 8. 0 is not a counting number.

As it is not clear what system it is, it is not possible to answer the question. If 10-, then 0 and 8. If 16, then 0,8,A,B,C,D,E,F etc etc...
