Integers

 

Operation of Integers
A. Basic Operation

1. Addition

(+)   +   (+)   =   (+)

(+)   +   (−)   =   (+) atau (−)

(−)   +   (+)   =   (+) atau (−)

(−)   +   (−)   =   (−)

2. Subtraction

(+)   −   (+)   =   (+) atau (−)

(+)   −   (−)   =   (+)

(−)   −   (+)   =   (−)

(−)   −   (−)   =   (+) atau (−)

 

3. Multiplication

(+)   ×   (+)   =   (+)

(+)   ×   (−)   =   (−)

(−)   ×   (+)   =   (−)

(−)   ×   (−)   =   (+)

4. Division

(+)   :   (+)   =   (+)

(+)   :   (−)   =   (−)

(−)   :   (+)   =   (−)

(−)   :   (−)   =   (+)

 

5. Exponent

\((+)^a = (+)\)

\((−)^a = (+)\) if a is even number

\((−)^a = (−)\) if a is odd number

 

B. Mixed Operation

Mixed operation on integers are solved according to the priority below:

1. Operation in parentheses

2. Operation in exponent

3. Operation of multiplication and division from left to right

4. Operation of addition and subtraction from left to right
