The integers consist of positive and negative

in adding integers you must give importance to the sign:

examples:

1. 1+1 = 2
2. -1+-1= -2

if there has a different sign but same in number the sum is ZERO

examples:
1. -10 + 10 = 0

if there has a differ. sign but differ. also in number you mus subtract it and the number that has the greatest value that will be the sign:

examples
1.  -10 + 9 = -1
2. -15 +25 = 10

The signed numbers are all part of the integers.
Positive numbers and negative numbers are the signed numbers.
When adding integers, for example -30+18=?, you look at the numbers, find out which number has a bigger absolute value (in this case it's -30), subtract like whole numbers (30-18=12) and then the sign of the number which has the bigger absolute value will be used.
So, -30+18=-12
When subtracting integers:
Ex. -20-5=?
You change the subtraction sign to the addition sign and then you make the 5 to -5.
So, it will be -20+-5=-25
