Explanation:
We need to explain the steps of adding and subtracting integers.
Note: Integers are the negative and positive whole numbers.
In order to add or subtract integers, we need to add same sign integers first and then we need to subtract opposite sign integers.
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.
