What is the distance of a number from zero on number line?

The distance of a number from zero on a number line is referred to as its absolute value. It is always a non-negative value, regardless of whether the number itself is positive or negative. For example, both -5 and 5 have an absolute value of 5, indicating they are each 5 units away from zero. The formula for calculating absolute value is |x|, where x is the number in question.
