The real-world problem that fits the sum -22 + 9 is:
Quinn is playing a card game with his friends. He had -22 points at the start of his turn, but just hit 9 points. How many does he now have?
In this scenario, the initial score of -22 represents points that Quinn is behind, and the +9 represents points he gained, resulting in the calculation of -22 + 9 to determine his new score.
