How many units must one move on the number line to go from 5 to 8?
Answer and explanation
Correct answer: 3 units
The distance between two numbers on a number line is the absolute value of their difference: \(|8-5|=3\) units. Therefore, one must move 3 steps to the right from 5 to reach 8. The value 13 is their sum, not the distance. In an exam, subtract the smaller number from the larger number to find the distance.
