The absolute value51 of a real number a, denoted | a |, is defined as the distance between zero (the origin) and the graph of that real number on the number line. Since it is a distance, it is always positive. For example, | − 4 | = 4 and | 4 | = 4. Both 4 and − 4 are four units from the origin, as illustrated below:Set Symbols.
