Understanding Absolute Value

The video tutorial explains the concept of absolute value, which measures a number's distance from zero on a number line. It demonstrates how to calculate the absolute value of both positive and negative numbers, emphasizing that the result is always non-negative. The tutorial provides examples, including the absolute values of -3, 3, -5, 12, and -129, and clarifies that while absolute values are typically positive, the absolute value of zero is zero, which is neither positive nor negative.

What does the absolute value of a number represent?

• Its value without any sign

• Its position on the number line

• Its negative counterpart

• Its distance from zero

How is the absolute value of a number typically represented?

• With parentheses

• With square brackets

• With vertical bars

• With curly braces

What is the absolute value of -3?

• -3

• 1

• 0

• 3

Why can't the distance between -3 and 0 be -3 units?

• Because distance is always positive

• Because -3 is not a valid number

• Because zero is not a number

• Because -3 is already positive
