Question

A segment is on a number line with endpoints at -2.5 and 6. What is the length
of the segment?

Answer 1

8.5

Explanation:

-2.5 - 6 = -8.5, but if -8.5 is the length of the line, then it wouldn't be possible to differentiate between the 2 points and find the length of the segment. So how do we tackle this issue? Simple, just count how many paces the segment has gone through from -2.5 to 6. Then, you'll find that the answer ends up being 8.5. I hope this helps :)
