Question 1149703
.
<pre>

The distance  " d "  between the numbers  -4  and  2  in number line is


    d = | 2 - (-4) | = | 2 + 4 | = |6 | = 6.


The same distance can be calculated in other way


    d = | (-4) - 2 | = | -6 | = 6.


The answer is the same, independently on the way you calculate it . . . 


    * * * Providing that the way you calculate it, is correct (!) * * *

The general rule is:  the distance between two numbers in number line is <U>ABSOLUTE VALUE of their difference</U>.
