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 change in temperature, where the initial temperature is negative, and the new temperature is positive, leading to the sum \(-22 + 9\).
