I used the formula =IF(A1=0,9,A1-1) to get this.  Notice that the top
and bottom numbers return to itself.  How do I do it on the + side?
Going past 10 is when it takes me for a loop.  I can understand the
simple -1 because 0 and 9 are the only two varibles but when adding it
goes up to 18.

This is what I am trying to achieve.

Each digit is treated differently than what you see in the example
above (all of the digits in that one are -1) but what I am trying to
achieve is for the first digit (4)+1, the second digit (9)+2, the third
digit (6) +3, and the fourth digit (3)+4.

When it goes above 10 is when it takes me for a loop.  Any help will be
appreciated.  Thanks.
