Express the distance between the numbers 2 and 17 using absolute value.And then, find the distance by evaluating the absolute value expression?

Step 1
Recall from childhood days:
The distance between two numbers M and N using absolute value = $|N-M|$
And $|A|=$
-A if $A\ge 0$
-A if A<0
Step 2
Hence, the distance between the numbers 2 and 17 using absolute value = $|17-2|$
Step 3
find the distance by evaluating the absolute value expression $=|17-2|=|15|=15$.
