Absolute Value for Beginners

The video tutorial explains the concept of distance, emphasizing that it is always non-negative. It then introduces absolute value, illustrating how it represents the non-negative distance on a number line. The tutorial further explores how absolute value affects equations, particularly in eliminating negative values, and uses examples to clarify these concepts.

Why can distance never be negative?

• Because it is always measured in a curved line

• Because it is always measured in a straight line

• Because it is always measured in a zigzag line

• Because it can be measured in any direction

What does absolute value represent on a number line?

• The negative distance from zero

• The positive distance from zero

• The distance from the lowest number

• The distance from the highest number

If a point is at -3 on a number line, what is its absolute value?

• 3

• -3

• 6

• 0

What is the absolute value of the expression 2 - 5?

• -3

• 5

• 3

• 7

How does absolute value affect negative numbers?

• It halves them

• It leaves them unchanged

• It turns them into positive numbers

• It doubles them
