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.

Yes, that’s correct! The scenario about the temperature change is a perfect fit for the sum \(-22 + 9\) because it deals with comparing two temperatures, one below zero and the other above zero, to find out how much warmer it has become.
