Comparing and Ordering Integers

Integers are the set of positive whole numbers, their opposites, and zero.

Two numbers that are the same distance from 0 on a number line, but in opposite directions, are opposites.

Example:

Find the opposite of 3 .

The opposite of 3 is + 3 , or 3 , because 3 and + 3 are each three units from 0 , but in opposite directions.

You can compare and order integers by graphing. Numbers increase in value from left to right.

Comparing Integers

Compare 5 and 2 using < , > , or = .

Since 5 is to the left of 2 on the number line , 5 < 2 .

Ordering Integers

In golf, the person with the lowest score is the winner. Rank the players at the right by ordering their scores from lowest to highest.

Player
Score
T.Woods
7
V.Singh
4
E.Els
+ 5
P.Mickelson
3
R.Goosen
+ 6

Graph the scores on a number line.

From lowest to highest scores, the players are T.Woods, V.Singh, P.Mickelson, E.Els, and R.Goosen.
