What is Absolute Value?
The absolute value of a number (denoted by |x|) is its distance from zero on the number line, regardless of direction. Key properties:
Always returns a non-negative value
|x| = x if x ≥ 0
|x| = -x if x < 0
Practical Applications of Absolute Value
Distance calculations in mathematics
Error margin computations in statistics
Voltage measurements in electronics
Vector magnitude in physics
Frequently Asked Questions
Can I calculate absolute value of fractions?
Yes! Enter fractions as decimals (e.g., 0.5 for 1/2) or use parentheses for complex expressions.
How does absolute value work with negative numbers?
The absolute value of any negative number is its positive equivalent. Example: |-5| = 5
What’s the absolute value of zero?
|0| = 0, as zero has no distance from itself.
Can I use this calculator for algebraic expressions?
While primarily for numerical values, simple expressions in parentheses can be evaluated.
