Think

1 is to the right of 7 on the number line,

so 1 is greater than 7.

Compare. Write , =, or .

Think

9 is to the left of 8

on a number line, so

9 is less than 8.

Think

5 is to the right of  6

on a number line, so

5 is greater than 6.

Compare and Order Integers

Objective To compare integers, with and without a number line • To order integers

A meteorologist recorded temperatures in

Juneau, Alaska, over a 2-day period. The

temperatures are shown in the table at the

right. Which day had a greater high temperature?

To find the greater high temperature, you can use a

number line to compare the integers 6 and 5.

Any number on a number line is greater than any

of the numbers to its left.

Since 6 is to the right of 5 on the number line, 6 is greater than 5.

So day 1 had a greater high temperature.

You can also use the symbols , , and to compare integers.

Compare:  1  7

So  1 7.

You can also compare the absolute value of integers.

Compare: | 3| |5| Write , , or .

3  5

So | 3||5|.
