Absolute Value

The absolute value of a number represents its distance from zero on a number line and is always a positive value or zero. It is defined mathematically as |a| = a for non-negative numbers and |a| = -a for negative numbers. Examples include |4| = 4 and |-4| = 4, illustrating that both have the same absolute value.

Absolute Value

The absolute value is always a positive number except for zero, as zero
is neither positive nor negative. Absolute value refers to the distance
of a number from zero, regardless of direction. The distance is always
positive, as absolute value of a number cannot be negative. Use this term
to refer to the distance of a point or number from the origin (zero) of a
number line. In other word, it is the magnitude of a real number without
regard to its sign.

Mathematically it is defined as
|a| =a where ‘a’ is non-negative real no.
|a|=-a where ‘a’ is negative real no.

Examples

| -4 | = 4. This means that the absolute value of "-4" is "4" because "-4"
is four units away from zero. Put another way:

|4| shows that the absolute value of 4 is 4.


|-4| shows that the absolute value of -4 is 4.
