8888 = 8
8889 = 7
...
4444=?
4444=0
0=1 Btw

Hmmm,
If it were my puzzle...
given that 8888=8 and 9999=4, I would actually have 6666=8 and then 4444=4

Which is fine if it's your puzzle...I probably agree to a point

...except for the 6666=8? I'd go as far even to go as far as to say that the 4 is the only 'unique' number in the puzzle, and is the only one that is dependant on the handwriting of the puzzle 'owner'. (too much info?)
