The document provides instructions and rules for adding, subtracting, multiplying, and dividing integers. It explains that when subtracting integers, you can change the problem to addition by "adding the opposite". It provides examples of applying the rules for adding, subtracting, multiplying, and dividing integers.

1. What did Usher do wrong? Find absolute value 6 – (-9) 6 + (-9) -9 is the largest so – + plus – means subtract -3

2. Human Number Line Adding look right Subtracting look left Positive walk forward Negative walk backward

3. 5 + 2

4. -2 + 4

5. 6-9

6. -3 – (-9)

7. 5 + (-4)

8. Subtracting Integers….. What are we really doing? ??!?!?

11. Subtracting Rules Change problem to addition by “adding the opposite” (+) - (+) = (+) + (-) (-) - (-) = (-) + (+) (+) - (-) = (+) + (+) (-) - (+) = (-) + (-) - 3 – (-5) 4 – 7 6 – (-9) -3 - 8

12. First ½ Sing to the tune of "Row Row Row Your Boat" Same sign add and keep Different sign subtract Take the sign of the farther number Then it'll be exact!

13. Is it an addition problem? Yes Look at the farthest number No Add the opposite Is the positive or negative number larger? Look at the fartheset number + is larger Final answer is positive - is larger Final answer is negative - Is the largest + Is the largest

16. Multiplying Rules + times - = - - times + = - + times + = + - times - = + -9(-10) 4 x -45 4 (30) (-9) •7

17. Dividing Rules + times - = - - times + = - + times + = + - times - = + -25 ÷ 5 -30 /-6 24/12 81 ÷ -9
