Simplifying Absolute Value Expressions
To simplify an expression involving absolute value, determine the distance of the number inside the bars from zero:
- , because is three units from .
- , because is forty-four units from .
- , because is zero units from itself.
Since absolute value measures distance, the result is always the non-negative version of the number inside the bars. For a positive number or zero, the absolute value equals the number itself; for a negative number, the absolute value equals its opposite.
