Absolute value of a number is equal to the numerical value of the number without considering sign of the number. Absolute value is defined as the distance or length between two points. The length of a quantity is always positive. We cannot measure a length in a negative scale. So, the absolute value cannot be negative. The absolute value of a number is always positive for example, absolute value of 1 is 1 and absolute value of -1 is also 1.
|1| = 1
|-1|= 1
|1| = 1
|-1|= 1
