Combining Two Opposites

The video tutorial explains the concept of opposites and absolute value using a number line. It demonstrates how adding a number and its opposite results in zero and how absolute value represents the distance from zero, always being positive. The tutorial includes examples and word problems, such as temperature changes, to illustrate these concepts. Viewers are encouraged to practice solving similar problems.

What is the result when you add a number to its opposite?

• The number itself

• Zero

• Negative of the number

• Double the number

What does the absolute value of a number represent?

• The sum of the number and its opposite

• The distance from zero on a number line

• The negative of the number

• The number itself

If the absolute value of -7 is calculated, what is the result?

• 7

• 14

• 0

• -7

What is the sum of the absolute values of -8 and +8?

• 32

• 0

• 16

• 8

In the context of temperature, what does the absolute value help determine?

• The lowest temperature

• The average temperature

• The total temperature change

• The highest temperature

If the temperature in Anchorage rises from -15°F to +15°F, what is the total increase?

• 45°F

• 15°F

• 30°F

• 0°F

How do you calculate the total temperature change from -5°F to +5°F?

• Subtract the lower temperature from the higher

• Add the absolute values of both temperatures

• Add the temperatures directly

• Multiply the temperatures
