4.3 Absolute or Numerical Value of an Integer

Numerical or absolute value of a directed number is a distance
from zero to that number on the number line. We shall make it
clear with an example.
Usman and Haris walked away 3 meters from the same place but
in the opposite directions. Who covered more distance? We display
this distance on the number line.

From the above number line we can observe that Usman and Haris version: 1.1
are at the same distance from the starting point 0. So, we can
say that the numerical or absolute value of 3 and –3 is the same
because it gives us only distance but not direction.
We can write it as: |+3| = 3
and |- 3| = - (- 3) = 3

Example 1: Find the numerical values of the following integers.
(i) – 4 (ii) 22 (iii) – 9

Solution:
(i) | - 4| = - (- 4) = 4 a Numerical value of – 4 is 4.
(ii) |22| = 22 a Numerical value of 22 is 22.
(iii) |- 9| = - (- 9) = 9 a Numerical value of - 9 is 9.
