Understanding Absolute Value

This video introduces the concept of absolute value, explaining it as the distance from zero. Using examples of people living on a street and a cruise ship, the video illustrates how absolute value is calculated for both positive and negative numbers. The absolute value of a number is always non-negative, representing its distance from zero, regardless of direction.

What is the primary concept of absolute value introduced in the video?

• The direction from zero

• The distance from zero

• The speed towards zero

• The time taken to reach zero

In the school example, if you live 3 miles to the left of the school, what is your position relative to the school?

• Positive 6 miles

• Negative 3 miles

• Positive 3 miles

• Zero miles

What does the absolute value of a negative number represent?

• The distance from zero

• Twice the number

• The negative of the number

• The number itself

If your position is at -3 miles, what is the absolute value?

• 3 miles

• -3 miles

• 0 miles

• 6 miles

What is the absolute value of a positive number?

• The negative of the number

• Zero

• The number itself

• Twice the number

In the cruise ship example, what is the position of the pool relative to sea level?

• Negative 20 feet

• Zero feet

• Positive 80 feet

• Negative 80 feet

What is the absolute value of the engine room's position if it is at -20 feet?

• 40 feet

• 0 feet

• -20 feet

• 20 feet

How is the absolute value of a position below sea level calculated?

• By adding the position to zero

• By taking the negative of the position

• By ignoring the negative sign

• By doubling the position

What does the absolute value of 80 feet represent in the cruise ship example?

• The total height of the ship

• The depth below sea level

• The distance from sea level

• The height of the engine room

Why is the absolute value important in understanding positions?

• It calculates the time taken to reach a point

• It measures the distance from a reference point

• It indicates the speed of travel

• It shows the direction of movement
