Absolute Value of an Integer

Absolute value of an integer is its numerical value without taking the sign into consideration.

The absolute values of -9 = 9; the absolute value of 5 = 5 and so on.

The symbol used to denote the absolute value is, two vertical lines (| |), one on either side of an integer.

Therefore, if 'a' represents an integer, its absolute value is represented by |a| and is always non-negative.

Note:
(i) |a| = a; when 'a' is positive or zero.

(ii) |a| = -a; when 'a' is negative.

Examples on absolute value of an integer:

(i) Absolute value of - 7 is written as |- 7| = 7 [here mod of - 7 = 7]

(ii) Absolute value of + 2 is written as |+ 2| = 2 [here mod of + 2 = 2]

(iii) Absolute value of - 15 is written as |- 15| = 15 [here mod of - 15 = 15]

(iv) Absolute value of + 17 is written as |+ 17| = 17 [here mod of + 17 = 17]

Find the mod of:

(i) |14 - 6| = |8| = 8

(ii) - |- 10| = - 10

(iii) 15 - |- 6| = 15 - 6 = 9

(iv) 7 + |- 7| = 7 + 7 = 14
