What is the absolute value of zero?

The absolute value of zero is 0. Absolute value represents the distance of a number from zero on the number line, regardless of direction. Since zero is exactly at the starting point, its distance from itself is zero. Mathematically, this is written as |0| = 0.This makes sense when you think about it - absolute value is always non-negative (positive or zero), and since zero isn't positive, the only possible value for |0| is 0 itself.
