What is the absolute value of -10?

The absolute value of a number refers to its distance from zero on a number line, without considering direction. In simpler terms, it is always a non-negative number, as it reflects how far a number is from zero. For the specific case of -10, the distance from zero is 10 units. Therefore, the absolute value of -10 is represented as 10. This aligns directly with the definition of absolute value, which always yields a positive result or zero (for the number zero itself). Thus, 10 is indeed the correct answer.
