Multiplying and Dividing Integers
When you MULTIPLY: • Two positives equal a
positive
• Two negatives equal a positive
• One positive & one negative equal a negative
(+)(+)= +
(–) (–) = +
(+) (–) = –
(–) (+) = –
Dividing IntegersThe rules are the same as
multiplication
When you DIVIDE: • Two positives equal
a positive
• Two negatives equal a positive
• One positive & one negative equal a negative
(+)÷(+)= +
(–) ÷ (–) = +
(+) ÷ (–) = –
(–) ÷ (+) = –
