# Pre-Algebra: Absolute Value

The absolute value of a real number is its numerical value without regard to its sign. So, for example, 3 is the absolute value of both 3 and −3.

The absolute value is closely related to the notions of magnitude, distance, and norm in various mathematical and physical contexts.

Absolute value of a number is the distance from the number on the number line to zero

Example:

|-7| = 7

| 7 | = 7
