Example 1 Compare Integers
Example 2 Order Integers
Replace the  with < or > to make –9  –5 a true
sentence.
Write the problem using a circle
for the comparison
-9
-5
We know that 9 is larger than 5
but when they are negative the
inverse is true
We can see this on a number line
Answer:
–9 < –5
Plot - 9
Plot - 5

Replace the  with < or > to make –3  –6 a true
sentence.
