Let's begin by recalling the definition of the absolute value.
Absolute Value of a Number
It is a distance between the number and 0 on a number line.
In other words, the absolute value of a number is the non-negative value of that number. The absolute value of a number a can be written as |a|.
|a| = a and |- a| = a
We want to find the absolute value of -5. To do this, we will plot this number on a number line and measure its distance.
The distance from the point to 0 is 5 units. Therefore, the absolute value of -5 is 5.
|- 5| = 5
