Understanding Absolute Value Concepts

This video tutorial explains the concept of absolute value, which is the distance of a number from zero on a number line. It uses examples to show how to calculate absolute values and graph them. The lesson also covers real-world applications, such as using absolute values in financial transactions. Additionally, it discusses comparing absolute values and concludes with a preview of the next lesson.

What is the absolute value of a number?

• The number itself

• The number squared

• The negative of the number

• The distance from zero on a number line

How is the absolute value of -3 represented?

• |-3|

• -3

• |3|

• 3

If a number is 4 jumps away from zero on a number line, what is its absolute value?

• 0

• 4

• 2

• -4

What is the absolute value of 0?

• 0

• 1

• -1

• Undefined

In real-world situations, why are absolute values often used instead of negative numbers?

• They represent distances or changes without direction

• They are more accurate

• They are easier to calculate

• They are always larger

If a $30 gift card is used for a $10 purchase, what is the absolute value of the change in balance?

• $10

• $20

• $30

• $40

Which statement is true about the absolute value of negative numbers?

• It is always greater than positive numbers

• It is always negative

• It is always positive

• It is always zero

What is the absolute value of -5 compared to 3?

• Cannot be determined

• Equal to 3

• Less than 3

• Greater than 3

Why can the absolute value of a negative number be greater than that of a positive number?

• Because positive numbers are smaller

• Because absolute value measures distance from zero

• Because negative numbers are larger

• Because it is a mathematical rule

What does the absolute value of a number represent in terms of jumps on a number line?

• The number of jumps to the nearest integer

• The number of jumps to the right

• The number of jumps to the left

• The total number of jumps from zero
