9. Adding Integers
Different Signs

10. Adding Integers! READY? OK!
If the signs are the same, you add the numbers and keep the same sign!
If the signs are different, you find the difference and keep the bigger sign!

11. How do you subtract integers?
Subtracting Integers
How do you subtract integers?
ADD THE OPPOSITE!

12. Multiplying Integers NO

13. Dividing Integers NO

14. Rational Numbers
Any number that can be written as a ration/fraction; decimals are terminating
Example
2/5
1/4
Non-Example
1/3
2/3

15. Ordering Rational Numbers
Order numbers from least to greatest
Put these numbers in order from least to greatest:
, .06, .12, .6, .78, .59
½, ¾, 3/5

16. Adding, Subtracting, Multiplying, Dividing
Fractions with like denominators
EX: 3/7 + 2/7
Fractions with unlike denominators
EX: 1/6 + ¾
Decimals
EX: / .6

17. PEMDAS P E M D A S
EX: (-2 + 4) – 3 – 8 ÷ 4 x =

18. ABSOLUTE VALUE |6| = |-5| = |0| = A number’s DISTANCE from zero…
The symbol for absolute value is | |.
|6| =  |-5| =  |0| =
