FOR ADDING INTEGERS
Addition of two positive numbers
(+a)+(+b) = (a+b) ex: 3+4=7 2+11=13
Addition of a positive number and a negative number
(a+(-b)) = (a-b) ex: 4+(-5)=(-1) (-5)+7=2
Addition of two negative numbers
(-a)+(-b) = -(a+b) ex: (-2)+(-4)=(-6) (-5)+(-8)=(-13)
i dont understand your question.
