Answer 1

Answer:

3. The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

4. Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is positive.
