Sure! Here's a real-life example word problem involving negative integers:
Scenario: A hiker starts from a campsite at an elevation of 500 meters above sea level. After hiking for a while, they descend down into a valley.
Problem: If the hiker descends 300 meters down into the valley, what will be the new elevation?
Solution:
1. Identify the initial elevation above sea level: 500 meters (positive integer).
2. Determine the descent into the valley: -300 meters (negative integer because the hiker is going down).
3. To find the new elevation, we need to add the descent to the initial elevation.
Initial elevation: 500 meters
Descent into the valley: -300 meters
Calculation: 500 + (-300) = 200
4. The new elevation after the descent into the valley is 200 meters above sea level (positive integer).
Therefore, the new elevation after the hiker descends 300 meters into the valley is 200 meters above sea level.
