Comparing and Ordering Integers
Additional Example 1: Comparing Integers Use the number line to compare each pair of integers. Write < or >.
A. –
B –5
C. –1 –4
–5 –4 –3 –2 –
–2 < 2
–2 is to the left of 2 on the number line.
3 > –5
3 is to the right of –5 on the number line.
–1 > –4
–1 is to the right of –4 on the number line.

Comparing and Ordering Integers
Try This: Example 1
Use the number line to compare each pair of integers. Write < or >.
A. –
B –3
C. –3 –4
–5 –4 –3 –2 –
–2 < 1
–2 is to the left of 1 on the number line.
2 > –3
2 is to the right of –3 on the number line.
–3 > –4
–3 is to the right of –4 on the number line.

Additional Example 2: Ordering Integers
Order 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.
–3 –2 –
Then read the numbers from left to right: –2, –1, 3.
Graph the integers on the same number line.
–6 –5 –4 –3 –2 –
Then read the numbers from left to right: –5, –3, 2, 4.

Try This: Example 2
Order the integers in each set from least to greatest.
A. –2, 2, –3
B. 6, –2, 5, –3
Graph the integers on the same number line.
–3 –2 –
Then read the numbers from left to right: –3, –2, 2.
Graph the integers on the same number line.
–6 –5 –4 –3 –2 –
Then read the numbers from left to right: –3, –2, 5, 6.

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? 1
Understand the Problem
The answer will be the player with the lowest score. List the important information:
Craig scored +2.
Cameron scored +3.
Rob scored –1.

Make a Plan
You can draw a diagram to order the scores from least to greatest.
Solve 3
Draw a number line and graph each player’s score on it. • • •
–3 –2 –
Rob’s score, –1, is farthest to the left, so it is the lowest score. Rob won the golf match.

Additional Example 3 Continued 4
Look Back
Negative integers are always less than positive integers, so neither Craig nor Cameron won the golf match.

15. Understand the Problem

Comparing and Ordering Integers
Try This: Example 3
In a golf match, Melissa scored +6, Trista scored –3, and Alyssa scored –1. Who won the golf match? 1
Understand the Problem
The answer will be the player with the lowest score. List the important information:
Melissa scored +6.
Trista scored –3.
Alyssa scored –1.

Make a Plan
You can draw a diagram to order the scores from least to greatest.
Solve 3
Draw a number line and graph each player’s score on it. • • •
–6 –5 –4 –3 –2 –
Trista’s score, –3, is farthest to the left, so it is the lowest score. Trista won the golf match.

17. Try This: Example 3 Continued
Course 1

Try This: Example 3 Continued 4
Look Back
Negative integers are always less positive integers, so Melissa cannot be the winner. Since Trista’s score of -3 is less than Alyssa’s score of -1, Trista won.
