A real-world problem that could be solved with the sum -22 + 9 might involve financial transactions. For example:
Scenario: Imagine you have a bank account balance that is currently overdrawn by $22, which means you are $22 in debt. If you receive a payment or deposit of $9 into your account, you can express the situation with the equation -22 + 9.
Problem Statement: You were $22 overdrawn on your bank account. After receiving a payment of $9, how much do you still owe?
Solution: The calculation -22 + 9 = -13 shows that you are now $13 overdrawn after the payment.
This context illustrates how the arithmetic expression relates to a real-life financial situation.
