Step-by-step explanation:
We need to explain the steps of adding and subtracting integers.
Note: Integers are the negative and positive whole numbers.
<em>In order to add or subtract integers, we need to add same sign integers first and then we need to subtract opposite sign integers.</em>
For example, if we are adding/subtracting -23+12-5+11, we would add same signs inegters -23 with -5 and 12 with 11.
On adding -23 and -5 we get -28.
On adding 12 and 11 we get 23.
Now, we need to subtract -28+23 as signs are different.
On subtracting, we get -5.
