Adding integers in real-world situations is a common task that can be applied in various contexts. Here are several examples of how this might occur:
-
Financial Transactions: When managing a budget, you might add your expenses (negative integers) and income (positive integers). For example, if you earn $500 and spend $200, you can add these integers to see your net gain: \[ 500 + (-200) = 300 \text{ (net gain)} \]
-
Temperature Changes: In weather forecasting, you might need to add temperatures that are above and below freezing. For instance, if the temperature rises from -5°C to 3°C, this can be calculated as: \[ -5 + 3 = -2°C \]
-
Sports Scoring: In games like basketball, points can be added to calculate total scores. If Team A scores 2, 3, and 4 points in different plays, you would add these together: \[ 2 + 3 + 4 = 9 \text{ points} \]
-
Elevation Changes: When hiking or driving, you might be interested in elevation changes. If you ascend 150 meters and then descend 50 meters, you can add these changes to find your net elevation gain: \[ 150 + (-50) = 100 \text{ meters} \]
-
Population Changes: In demographic studies, you might add populations from different regions. If Region A has 1,200 residents and Region B has 800 residents, you determine the total population as follows: \[ 1200 + 800 = 2000 \text{ residents} \]
-
Construction Projects: When calculating materials needed for building, you may add quantities together. For instance, if you need 25 bricks for one wall and 30 for another, the total would be: \[ 25 + 30 = 55 \text{ bricks} \]
-
Travel Distances: When planning a trip, you might add up distances from different legs of the journey. If you drive 120 miles and then another 80 miles, your total distance traveled is: \[ 120 + 80 = 200 \text{ miles} \]
In each of these examples, adding integers helps you make informed decisions and accurately assess situations based on numerical data.
