The sum −22+9 is a mathematical operation that gives us a result of -13. It represents the addition of a negative number (-22) and a positive number (9).
In terms of a real-world problem that could be solved with this sum, let's consider an example:
Imagine you have a checking account with a balance of $22, but you owe $9 to a friend. The negative sign indicates that you owe this amount. To find out how much money you have left after paying your friend, you can use the sum −22+9.
To solve the problem:
1. Start with the initial balance, which is -$22.
2. Add the amount you owe to your friend, which is +$9.
3. Add the two numbers together: -22 + 9 = -13.
4. The result, -13, represents the remaining balance in your checking account after paying your friend.
So, in this real-world example, the sum −22+9 can be used to calculate the remaining balance in your checking account after paying a debt.
