Let's solve each problem step by step. The task is to
find the distance between two marked points on a number line. Distance is always
positive, so we take the
absolute value of the difference between the two numbers.

Key Concept:
Distance between two points on a number line is the
absolute value of their difference:
$$
\text{Distance} = |a - b|
$$
This ensures the result is always positive, regardless of order.
