The absolute value of a number can be considered as the distance between 0 and that number on the real number line.
Remember that distance is always a positive quantity (or zero).
The distance in the diagram above from +4 to 0 is 4 units and the distance from -3 to 0 is 3 units. These units are never negative values.

Absolute Value of an Integer:
The absolute value of an integer is the numerical value (magnitude) of an integer regardless of its sign (direction). It is denoted by the symbol ? ?. The absolute value of an integer is either zero or positive. Also, the corresponding positive and negative integers have the same absolute value.
The absolute value of -2 is ?-2? = 2.
The absolute value of 5 is ?5? = 5.
The absolute value of 0 is ?0? = 0
