Answer 1

You can use a simple expression like this:

(n<0?"":"+") + n

The conditional expression results in a plus sign if the number is positive, and an empty string if the number is negative.

You haven't specified how to handle zero, so I assumed that it would be displayed as +0. If you want to display it as just 0, use the <= operator instead:

(n<=0?"":"+") + n
