INTEGERS AND ABSOLUTE VALUES
Absolute value of an integer :
The absolute value of an integer is the numerical value of the integer irrespective of its sign the symbol ‘| |’ is used to represent the absolute value of an integer. Thus |+8| = +8 , |-8| = 8
This shows that the absolute value of an integer is either equal to or greater than the integer but never less than the integer
Let ‘a’ be a real number
|a| = +a, if a is +ve
|a| = 0 if a= 0
|a| = -a, if ‘a’ is negative Ex : |5| = +5 |-5| = +5
