Absolute Value

The positive value for a real number, disregarding the sign.





The absolute value of a negative number is obtained by multiplying the number by -1

If a number r is denoted |r|

|r|=r for r≥0

|r|=-r for negative r

|r| is the distance from number r to the origin. In this form, the definition applies to complex numbers that are identified with points in the plane.
