Hi warren,

While your method works to an extent I wouldn't use it because it can cause
problems with logical comparisons.

Try my formatting method in c1 and your method in d1 then do a logical
compare back to the 2 original numbers in a1 & b1

Your method in d1 evaluates as false
=D1=B1-A1

The format method in c1 evaluates as true
=C1=B1-A1

Dear Excel experts,

I am comparing the values of cells in two columns: if difference B1-A1 is
<0, then the minus sign logically appears before the value.

But how can I make a "+" sign appear when difference B1-A1 0?

A thousand of thanks for your help!
