The real-world problem that could be solved with the sum \(-22 + 9\) is:
The temperature was −22°F yesterday. Today the temperature is 9°F. How much warmer is it today compared with yesterday?
This scenario involves calculating the difference in temperature, which is effectively finding the total change in temperature from \(-22\) to \(9\). In this case, the sum represents how much warmer it is from the previous day's temperature to the current one.
