I am trying to subtract 1 from each position in my number, example position
1=0, position 2=9, position 3=7. 0-1 = -1, 9-1=8, 7-1=6. If the number in
any positon is a zero(0), then I want the new number to become a 9, instead
of a -1. I'm sorry I didn't make that clear in my first post.

Just add 1000. Or, if the number of digits being subtracted can vary, add
10^numdigits
