                               Examples:    Add :

 

1.  -9 + (-7) = -16

 

5.   6 + (-2) = 4

2.   –20 + 15 = -5

 

6.   (-21) + 21 = 0

3.   (-23) + (-7) = -30

 

7.   –3 + 8 = 5

4.   (+3) + (+5) = 8

 

8.   -9 + 6 = -3

9.  Add -9 and -5.  -9+-5=-14

 

 

10.  Add (-7), (+3), and (-12).  -7+3+(-12)=-19+3=-16 

 

Examples:      Subtract :
 

1.  

9 – (3) =

5.

-10 - (15) =

 93=6

 –10+(–15)= –25

 

2.

-7 – (5) =  

6.

-25 - (25) =

 –7 + (–5)= –12

 –25 + (–25)= –50

 

3.

21 – (19) =     

7.

3 - (-5) =

 21 + (–19) = 3

 3 + 5 = 8

 

4. 

- 5 - 4 =     

8.

9 - 3 =

 –5 + (-4) = –9

 – 3 =6

 

 

9.   Subtract (-5) from (10).
     10 – (–5) = 10 + 5 = 15  

 

 

10.   Subtract 4 from (-14).

–14 – 4 = –18
