5. Addition of Integers

6. • 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

8. • Add the opposite and refer to the addition
rules (change the subtraction to addition and
change the sign of the number being
subtracted)

9. Multiplication of
Integers

10. • 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
