2.  Lets Review Integers (you do not need to write this part down)

3. Integers -The set of positive whole numbers, negative whole numbers, and zero. -5 -4 -3 -2 -1 0 1 2 3 4 5 Positive Integers Negative Integers Origin

4. 1.1 Integers and Absolute Value Start writing this down

5. Absolute Value Absolute Value -The distance a number is from zero on the number line. -5 -4 -3 -2 -1 0 1 2 3 4 5 34 Evaluate the absolute value. 1) 2) 3) 4) So… Absolute value always results to be a positive number.

6. Compare Using or = ExamplesSteps: 1.Find the absolute value 2.Then compare 4 < 7 5=5

7. Order the Values from least to greatest exampleSteps: 1.Find the absolute value 2.Order 6,-7,8,5,-6 -7,-6,5,6,8,

8. Simplify when - Examples:Steps: 1.Find the absolute value 2.Multiply by -1 -1 (3) = -3 -1 (3) = -3

9. 1.2 Adding Integers

10. How do you add integers with the same sign? 1.Find the absolute values 2.Find the sum of the absolute values 3.Apply the sign of the integers to the sum (Don’t Write) Essential Question

11. Write this down: Same sign add and keep!!

12. Examples: 1.) -22 + (-16) 2.) -60 + (-13) 3.) 125 + 35 Add the integers. Same sign add and keep!! -38 -73 160

13. How do you add integers with different signs? 1.Find the absolute values 2.Subtract the smaller absolute value from the larger. 3.Use the sign of the integer with the greater absolute value. (Don’t write) Essential Question

14. Write this down: Different sign subtract Keep the sign of the larger number

15. Examples: 1.) -51 + 20 2.) 13 + (-13) 3.) 10 + (-18) 4.) 25 + (-26) Add the integers. -31 0 -8

16. Use the Commutative and Associative Properties to help find the sum Adding more than two terms

17. 264 Example: 180 +20 +64 Commutative property (180 +20) + 64 Associative Property 200 +64

18. Example -20 + (-15) + 30 + (-1) Could you use the commutative property? What would you add together first? -20 + (-15) + (-1) +30 commutative [-20 +(-15) + (-1)] + 30 Associative -36 +30 -6
