1. INTEGERS & ABSOLUTE VALUE

3. The set of integers is composed of the counting (natural ) numbers, their opposites, and zero.24
-49 -3 1 -1
-99 49
-24 12 3
-12 99

4. and decrease in value to the left (…-3, -2, -1, 0)
Beginning with zero, numbers increase in value to the right
(0, 1, 2, 3, …)
and decrease in value to the left (…-3, -2, -1, 0)

5. When comparing numbers the order in which they are placed on the number line will determine if it is greater than (>)or less than (<) another number.

6. If it is to the right then it is greater than that number.
If a number is to the left of a number on the number line, it is less than the other number.
If it is to the right then it is greater than that number.
-10 < < < < 10
-5 > > > > 5

7. Absolute value is the distance a number is from zero on a number line
Absolute value is the distance a number is from zero on a number line. We use |n | to indicate absolute value.
Example:
|-7| = 7

8. Application: Answer : 4 Example:
Jack Nicklaus is –4 after 36 holes of golf. How many strokes away from even par is he? (Par for a course is a score of zero strokes above or below.)
Answer : 4

9. Absolute Value is the distance a number is from zero on the x or y axis.
It doesn’t matter whether the number is left, right, north or south of the origin, its distance is always POSITIVE
