Operations with Integers 
 
 
 
 
Addition → Sum 
Subtraction → Difference 
Multiplication → Product 
Division → Quotient 
 
Positive → Go forwards on number line 
Negative → Go backwards on number line 
 
Addition and Subtraction 
(Start at zero, then find the first number on the number line
...

 
Examples: 1) ­3 + 2 = ­1 
       2) 5 ­ 8 = ­3 
       3) ­5 + 10 = 5 
 
Cancelling Out Negatives and Positives 
Use ­9 + (­6) as an example
...
 Since the second integer is negative, and the process is addition, you can 
cancel it out and subtract instead
...
 Adding a negative → Subtract 
Ex: 4 + (­3) = 1 
2
...
 Adding a negative → Subtract 
Ex: 4 ­ 3 = 1 
2
...
 An 
example is 6 ÷ ­2
...
 
When you make it ­2 though, you must switch the answer’s symbol
...
  
 
One positive, one negative → Negative 
Two negatives → Positive 
Two positives → Positive 
 
Examples: 1) 5 ÷ ­5 = ­1 
       2) 3 × ­3 = ­9 
       3) ­2 × ­8 = 16 
       4) ­8 ÷ ­2 = 4
