 Is Luke correct?

Luke's method is correct, and his answer is accurate. Here's how we can break it down:

The change in temperature from morning to afternoon can be found by subtracting the morning temperature from the afternoon temperature. So, we calculate:

\[
\text{Change in temperature} = \text{Afternoon temperature} - \text{Morning temperature}
\]

Given:
- Morning temperature = \(-10^\circ C\)
- Afternoon temperature = \(-2^\circ C\)

Now, we perform the subtraction:

\[
-2^\circ C - (-10^\circ C)
\]

This simplifies to:

\[
-2^\circ C + 10^\circ C = 8^\circ C
\]

So, the temperature rose by \(8^\circ C\). Luke's answer is indeed correct.

Would you like more details, or do you have any questions? Here are 5 related questions you might want to explore:

1. How would the change be calculated if the temperatures were in Fahrenheit?
2. What if the morning temperature was \(5^\circ C\) and the afternoon temperature was \(-3^\circ C\)?
3. How do negative numbers affect calculations in real-world problems like temperature?
4. What is the difference between absolute temperature changes and temperature changes that involve negative numbers?
5. How would we represent the same temperature change using the Kelvin scale?

**Tip:** When subtracting negative numbers, remember to "flip" the sign of the second negative number—it becomes addition!

In the morning, the temperature was -10°C. By the afternoon, it had risen to -2°C. What was the change in temperature from the morning to the afternoon? Luke subtracted -2 - (-10) and came up with an answer of 8°C. Is Luke correct?

Learn how to calculate the change in temperature from -10°C to -2°C and check if Luke's method is correct. This problem involves subtraction of negative numbers and properties of integers. Suitable for students in Grades 6-8.
