1. Integers

2. Integers Integers are positive (+) and negative(-) numbers.
Negative Integers represent a loss or a decrease. (Ex. -5, -18, -345, ...)
Positive Integers represent a gain or an increase. ( Ex. +3, +25, +467, ...)

3. Positive Integers + 25 +6 +3 +5
Emmit Smith gained 25 yards on his last play.
The elevator went up 6 floors.

6. -3 and +3 are opposites because they are both 3 units from zero
Opposite Integers
3 units
3 units -3 +3
Integers that are the same distance from zero are OPPOSITE integers.
-3 and +3 are opposites because they are both 3 units from zero

7. Absolute Value I 2 I = I - 4 I =
The absolute value of a number tells how far an integer is from zero.
The symbol for absolute value is I I
I 2 I = I - 4 I =
2 units from zero
4 units from zero

8. Absolute Value Find the absolute value of : I - 25 I I 43 I I - 768 I
Find the absolute value of :
I - 25 I I 43 I I I
= 768
= 25
= 43

11. Comparing Positive Integers are like money you have.
The higher the positive number the richer you are.
Negative Integers are like money you owe. The higher the negative number the poorer you are

12. Integers on a Number Lin e
smaller
bigger
Which is greater? or +2
Which is greater? +5 or +3
Which is smaller? -4 or -10
Which is smaller? -6 or 0
Positives are always greater than negatives.

13. Opposites
Positive integers have an opposite Negative integer.
Opposites are the same distance from 0 on the number line in opposite directions.
Ex.
opposite of _______
opposite of _______
opposite of _______
opposite of _______
+16 -4
+67
-35

14. Order The number line can also help you put integers in order.
If the numbers are written down as they would appear on the number line, they will be in order from least to greatest.
Order from least to greatest.

15. How did you do?
-7, -4, -2, 0, +1, +5, +6
Good Job!!!!!
