3. Positive Numbers
Most numbers you have seen so far have been greater than or equal to 0.
Numbers greater than 0 are called positive numbers.
They are represented by a + to show they are positive.

4. Negative Numbers Numbers less than 0 are negative numbers.
Negative numbers are always shown with a minus (-) sign.
You will also see them with parentheses to keep the negative sign with the correct number.
Example 4 + (-3)

5. Number Lines
On a number line, the further right the number is, the greater it is.
Example 5 and 8:
The 8 is further to the right so, it’s greater than 5
On a number line, the further left it is, the less it is.
Example -11 and -9
The -11 is further to the left so it is less than -9.

6. Zero is the Starting Point
Zero is not negative or positive.
Positive numbers are always greater than negative numbers.
Example 7 and -3
Negative numbers are always less than positive numbers.
Example and 44

7. Write each number as an integer:
Ethanol freezes at 114° C below zero
Matt is 59 inches tall.
Kathy lost 4 pounds.
Dave has a debt of $24.
Julia hopped 5 ft. backwards.

8. Compare these integers.
-7 _____ -10
Hint: Which integer is closer to zero?
It is greater than the other integer.
-6 _____ 13
-3 ______ 3
6 ______ -6
-55 ______ -32

9. Opposites The opposite of any negative number is its positive number.
You get to zero when you add them together.
Example: The opposite of -76 is 76
The opposite of 13 is -13
