Find the Absolute Value of a Number

The absolute value of a number is the positive value of that number. It tells you how far away from 0 a number is on the number line. The symbol for absolute value is a set of vertical bars.

Taking the absolute value of a positive number doesn’t change that number’s value. For example,

|3| = 3

|12| = 12

|145| = 145

However, taking the absolute value of a negative number changes it to a positive number:

|–5| = 5

|–10| = 10

|–212| = 212
