Lesson 12-1

Example 1 Compare Integers
Replace the • with <, >, or = to make a true sentence.
−3 • −8

Graph –3 and –8 on a number line. Then compare.  

Since −3 is to the right of −8, −3 > −8.

Example 2 Order Integers
Order –5, 8, −8, and 1 from least to greatest.

Graph the numbers on a number line.

The order from least to greatest is −8, −5, 1, and 8.

Example 3 Real-World Example
TEMPERATURE   Suppose the daily high temperatures for the past four days were −6°F, 12°F, −3°F, and 1°F. Order the temperatures from least to greatest.

First, graph each integer. Then, write the integers as they appear on the number line from left to right.  

The order from least to greatest is −6°, −3°, 1°, and 12°.
