[It is mathematical convention to show only the negative sign and the plus sign.
How to remove the bracket. Multiply the "plus" sign [This is not shown explicitly] with minus sign.
The result is minus sign.
You are to add two signed numbers
One is negative another is positive.
Find the difference. It is
The forget the sign. Find the biggest number. Identify the sign of that number.
Place it before the result
