The problem that could be solved with the sum −22+9 is determining the net change in temperature.

To solve the sum −22+9, you simply need to add the two numbers together.

-22 + 9 = -13

Now, to address your question about a real-world problem that could be solved with this sum, one possible scenario could involve a person's monthly expenses and income. Let's suppose that a person's total monthly expenses amount to $22, while their monthly income is $9. In such a situation, the sum −22+9 would represent their financial status at the end of the month.

If we consider the expenses as negative and the income as positive, the sum −22+9 would indicate a deficit or shortfall in their budget. This means that they spent $22 more than they earned, resulting in a negative balance of $13 for the month. This shortfall could signify the need to find ways to either increase their income or reduce their expenses to achieve a balanced budget.
