Multiplying and Dividing Intergers


Homework: page 291-292 #5-8 and #13-20
Rules:
1. do the number
find out the answer to the question

2. apply the rule
find out if it is a - or +

When the two integers are the same multiplied or divided they will always equal a positive
(+3) x or / (+7) = (+21)
(-3) x or / ( -7) = (+21)


When the two integers are different multiplied or divided they will always equal a negative

(-3) x or /(+7) = (-21)
(+3) x or / (-7) = (-21)

Remember: to put in Math game on new post
