Absolute Value

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always a non-negative number.

Absolute value is represented using vertical bars, for example, |x|.

The absolute value of -7 is 7, written as |-7| = 7.

The absolute value of 0 is 0, written as |0| = 0.

The possible values of x are 5 and -5.

Absolute value represents distance, which is always a non-negative quantity.

Yes, the absolute value of a positive number is the same as the number itself.

The absolute value of |-3| is 3, written as |-3| = 3.

To solve |x| = 4, set up two equations: x = 4 and x = -4.

It means that x is within a distance of a from 0, or -a < x < a.
