Real Life Example of Adding Two Negative Integers
In daily life, a common scenario where we have to add two negative integers is when we are calculating financial debts. For example, if a person owes $50 to one friend and $30 to another friend, the total amount of money owed would be the sum of these two debts, which would involve adding two negative integers.

Property of Adding Two Negative Integers
When adding two negative integers, the property that applies is the addition of integers with like signs. In this case, since both integers are negative, we follow the rule that when adding integers with the same sign, we add their absolute values and keep the negative sign.

Explanation
- In the example mentioned above, adding $50 and $30, both being debts, involves adding two negative integers.
- We first find the absolute values of the integers, which are 50 and 30.
- Then, we add these absolute values, 50 + 30 = 80.
- Since both integers are negative, the sum will also be negative. Therefore, the total debt would be -$80.
By understanding the concept of adding two negative integers in real-life scenarios like calculating debts, we can apply the property of adding integers with like signs to arrive at the correct sum. This helps in better financial planning and management by accurately calculating and tracking debts or expenses.
