Understanding Absolute Values

This video tutorial explains the concept of absolute values, which represent a number's distance from zero on a number line, always as a positive value. It covers how to calculate the absolute value of both positive and negative numbers, and explores the concept of negative absolute values, where the result is the opposite of the absolute value. The tutorial uses examples to illustrate these concepts, emphasizing that the absolute value is always positive unless specified otherwise.

What is the absolute value of a number?

• The number squared

• The negative of the number

• The distance from zero

• The number itself

How is the absolute value of a number represented?

• With parentheses

• With square brackets

• With vertical bars

• With curly braces

What is the absolute value of -4?

• 4

• 8

• 0

• -4

If the absolute value of a number is 3, what could the original number be?

• Only 3

• -3 or 0

• 3 or -3

• 3 or 0

What does a negative sign outside the absolute value indicate?

• The absolute value is positive

• The result is negative

• The number is zero

• The number is squared

What is the result of -|6|?

• 6

• 12

• -6

• 0

What is the opposite of the absolute value of -8?

• 8

• -8

• 0

• 16

How many units is -8 from zero on the number line?

• 16 units

• 0 units

• -8 units

• 8 units

What happens to the result when there is a negative sign outside the absolute value?

• It becomes positive

• It becomes negative

• It becomes zero

• It remains the same

What is the key takeaway about absolute values?

• They are always negative

• They are always positive

• They can be either positive or negative

• They are always zero
