1. Types of Numbers Whole numbers 0, 1, 2, 3, 4, 5, …
Natural numbers 1, 2, 3, 4, 5, …
Integers …-4, -3, -2, -1, 0, 1, 2, 3, 4…

2. Integers Opposites Absolute value
2 numbers the same distance from zero
Ex.: 8 and -8
Absolute value
How far a number is from zero (distance)
Shown as | 5 | or | -4 |
ALWAYS positive!!!!

3. Integers
Are all whole numbers and…
…their opposites

4. Comparing integers… +4 -5 < -3 |-3| > -1 7 |8| > -|-9|= ?
Numbers to the left on the number line are smaller than those to the right -5
< -3
|-3|
> -1 7
|8|
>
-|-9|= ?
What is the opposite of the opposite of the opposite of negative 4? +4

5. Graphing in 4 quadrants ordered pair (5, 4) origin (0, 0) coordinates
y-axis
ordered pair
(5, 4)
origin
(0, 0)
coordinates
x-axis
(x, y)

6. In your notebooks, graph these points:
Can you find a “rule” that compares x and y ?
