Multiplying Integers
Multiply the numbers as usual, then apply the sign rule: matching signs give a positive answer, different signs give a negative answer.
What You'll Learn
Multiply the numbers first, ignoring the signs.
Matching signs (both positive or both negative) give a positive answer.
Different signs give a negative answer.
Negative 3 times negative 4 equals positive 12.
The same sign rules apply to dividing integers.
