Multiplying Two Positive Integers
When multiplying two positive integers you multiply the magnitudes of
the factors and the sign remains positive.
Multiplying Two Negative Integers
When multiplying two negative integers you multiply the magnitudes of
the factors and the sign changes to positive.
Multiplying A Positive and a Negative Integer
When multiplying a positive and a negative integer you multiply the
magnitudes of the factors and the sign is negative.
Dividing Two Positive Integers
When dividing two positive integers you divide the magnitude of the
dividend by the magnitude of the divisor and the sign remains positive.
Dividing Two Negative Integers
When dividing two negative integers you divide the magnitude of the
dividend by the magnitude of the divisor and the sign changes to positive.
Dividing A Positive and a Negative Integer
When dividing a positive integer and a negative integer you divide the
magnitude of the dividend by the magnitude of the divisor and the sign is
negative.
