In mathematics, the absolute value or modulus of a real number , denoted , is the non-negative value of without regard to its sign. Namely, if is a positive number, and if is negative (in which case negating makes positive), and . For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3.

The absolute value of a real number is the distance of the number from \ (0\) on a number line. The absolute value of \ (x\) is written as \ (\left|x\right|.\) For example, \ (\left|5\right| = \left|-5\right| = 5.\) This is a special case of the magnitude of a complex number.
The absolute value of a number \(a\), denoted \(|a|\), is the distance from a to 0 on the number line. Absolute value answers the question of "how far," and not "which way." The phrase "how far" implies "length" and length is always a nonnegative quantity .
Absolute Value means ..... how far a number is from zero: "6" is 6 away from zero, and "−6" is also 6 away from zero. So the absolute value of 6 is 6, and the absolute value of −6 is also 6 . Absolute Value Symbol. To show we want the absolute value we put "|" marks either side (called "bars"), like these examples:
