Division
Addition of Integers
•
When the signs of the numbers being added
are the same, add their absolute values--The
sign of the answer is the same as the sign of
the numbers added together
•
When the signs of the numbers being added
are different, subtract their absolute values--
The sign of the answer is the same as the
number with the largest absolute value
Subtraction of
Integers
•
Add the opposite and refer to the addition
rules (change the subtraction to addition and
change the sign of the number being
subtracted)
Multiplication
of
Integers
•
When the sign of the numbers being
multiplied are the same, multiply the
numbers--The sign of the answer is positive
•
When the sign of the numbers being
multiplies are different, multiply the
numbers--The sign of the answer is negative
Division
of
Integers
•
Same as the rules for multiplication of
Integers
