Hi Brian-123
Type 1.1 in a spare cell, copy it, select your column and Paste, Special Values, Multiply. Then type 1 in a spare cell, copy it, select your column and Paste, Special Values, Add. That will increase the value of your cells by 10% then increase that value by 1.
Afraid I do not follow why you would then want to delete the column.
Hope this helps
regards
Derek
