Integers

100

Adding Integers 

-6 + -12

-5 + 14

23 + -8

34 + -74

Adding Integers 

-6 + -12 = -18

-5 + 14 = 9

23 + -8 = 15

34 + -74 = -40

200

Subtracting Integers

-35 - -49

-20 - 18

-15 - -15

48 - -52

Subtracting Integers

-35 - -49 = -35 + 49 = 14 

-20 - 18 = -38 

-15 - -15 = -15 + 15 = 0 

48 - -52 = 48 + 52 = 100

300

Multiply the following

-8 x -20

-5 x 13

9 x 14

12 x -2

86 x 0

-8 x -20 = 160 * multiplying two negatives gives us a positive answer  

-5 x 13 = -65

9 x 14 = 126

12 x -2 = -24

-86 x 0 = 0 * zero times anything will always be zero 

400

Dividing Integers 

144 / - 12

-180 / 3

-81 / -9

100 / 5

144 / - 12 = -12

-180 / 3 = -60

-81 / -9 = 9

100 / 5 = 20

500

Identify if the following answers are incorrect, answer the following in your own words:

Why? What should be the correct answer?

-25 / 5 = 5

-13 + -24 = 11

-13 - -14= -17

-15 x -15 = 0

- 13 + - 12 = 1

All of the following were incorrect, in your own words answer: 

Why? What should be the correct answer?  

-25 / 5 = 5  

-13 + -24 = 11  

-13 - -4= -17   

-15 x -15 = 0   

- 13 + - 12 = 1
