the integers in each set from least to
greatest. A. 2, 3, 1 B. 4, 3, 5, 2
Graph the integers on the same number line.

Additional Example 3 Problem Solving
Application
In a golf match, Craig scored 2, Cameron scored
3, and Rob scored 1. Who won the golf match?

• The answer will be the player with the lowest
  score. List the important information
• Craig scored 2.
• Cameron scored 3.
• Rob scored 1.

11
Additional Example 3 Continued
You can draw a diagram to order the scores from
least to greatest.
Draw a number line and graph each players score
on it.



Robs score, 1, is farthest to the left, so it
is the lowest score. Rob won the golf match.
12
Additional Example 3 Continued
Look Back
Negative integers are always less than positive
integers, so neither Craig nor Cameron won the
golf match.

Check It Out Example 3
In a golf match, Melissa scored 6, Trista scored
3, and Alyssa scored 1. Who won the golf match?

• The answer will be the player with the lowest
  score. List the important information
• Melissa scored 6.
• Trista scored 3.
• Alyssa scored 1.

Check It Out Example 3 Continued
You can draw a diagram to order the scores from
least to greatest.
Draw a number line and graph each players score
on it.



Tristas score, 3, is farthest to the left, so
it is the lowest score. Trista won the golf match.
15
Check It Out Example 3 Continued
Look Back
Negative integers are always less than positive
integers, so Melissa cannot be the winner. Since
Tristas score of 3 is less than Alyssas score
of 1, Trista won.
