The absolute value of 8 is 8.

In symbols: |8|=8

Explanation:

The absolute value of a number is its 'size'. For positive numbers the size is the same as the number. For negative numbers it is the corresponding positive number.

In symbols:

|x|=|x|=x when x0

Another way of thinking of it is to imagine numbers laid out in order, evenly spaced on a line with 0 at the centre, negative numbers on the left and positive numbers on the right, with 1 being a unit distance from 0. The absolute value of any number is then its distance from 0.
