Multiplying and
Dividing Integers
The ‘good guys’ against the
‘bad guys’
Positive numbers are the
‘good guys’
When
something
Good happens
To the good guy,
The outcome is
Positive.
Positive numbers are the
‘good guys’
When
something
Good happens
To the good guy,
The outcome is
Positive.
Positive Outcomes
A positive times a positive is a
positive.
(+)5 * (+)7 = (+)35
Negative numbers are
the ‘bad guys’
When something
Bad happens
To the bad guys
The outcome is
Positive.
Positive Outcomes
A negative times a negative is
a positive.
(-)4 * (-)3 = (+)12
Negative Outcomes
When
something
Bad happens
To the good guy
The outcome
Is negative.
Negative Outcomes
A negative times a positive is
a negative.
(-)3 * (+)8 = (-)24
Negative Outcomes
When
something
Good happens
To the bad guy
The outcome is
Negative.
Negative Outcomes
A positive times a negative is
a negative.
(+)6 * (-)7 = (-)42
Division
The same rules work for
division.
(+)24 ÷ (+)6 = (+)4
(-)25 ÷ (-)5 = (+)5
(-)48 ÷ (+)6 = (-)8
(+)36 ÷ (-)9 = (-)4

So the next time you are
trying to remember how to
