What is the result of subtracting a negative number from a negative number?

Back

When you subtract a negative number, it is equivalent to adding its absolute value. For example, -2 - (-2) = -2 + 2 = 0.

If the temperature is 71°F and it drops 5°F, what is the new temperature?

Back

The new temperature is 71°F - 5°F = 66°F.

Front

If the temperature then rises 8°F from 66°F, what is the final temperature?

Back

The final temperature is 66°F + 8°F = 74°F.

Front

How do you calculate the change needed to return to the original temperature from a new temperature?

Back

To return to the original temperature, subtract the new temperature from the original temperature. For example, 71°F - 74°F = -3°F, meaning it needs to fall 3°F.

Front

What does the expression (-4) - 6 represent on a number line?

Back

It represents moving 4 units to the left from 0, then moving an additional 6 units to the left, landing at -10.

Front

How do you find the distance between two negative integers on a number line?

Back

To find the distance, subtract the smaller integer from the larger integer and take the absolute value. For example, the distance between -12 and -20 is |-12 - (-20)| = |-12 + 20| = |8| = 8.

Front

What is the significance of integers in real-world contexts, such as temperature and elevation?

Back

Integers can represent quantities that can be above or below a reference point, such as temperature above or below freezing, or elevation above or below sea level.

Front

What integer represents the highest elevation in the world?

Back

The integer that represents the highest elevation in the world is 29,035 feet, which is the height of Mount Everest.

Front

What integer represents the lowest elevation in the world?

Back

The integer that represents the lowest elevation in the world is -413 feet, which is the depth of the Dead Sea.

Front

How do you interpret negative integers in terms of elevation?

Back
