Adding Rational Numbers in the Real World: Decimals

The video tutorial explains how to calculate temperature changes over time by adding rational numbers. It covers the addition of negative numbers and the process of determining the total temperature change from 5:00 PM to midnight. The tutorial also demonstrates how to find the final temperature at midnight by adding numbers with different signs, emphasizing the importance of absolute values and sign determination. The lesson concludes with a real-world application of these mathematical concepts.

If the temperature at 5:00 PM was 85.2 degrees Fahrenheit, what is the temperature at midnight?

Explain how to find the temperature change when the signs of the addends are different.
