Dividing Integers

2
Use the same rules as Multiplying Integers
Dividing Integers with DIFFERENT signs
--> the answer will be negative!
(+)÷(−) = −
positive÷negative=negative
Dividing Integers with the SAME sign
--> the answer will be positive
(+)÷(+)=+
(−)÷(−)=+
3
Division can look like...
this --> −10÷2=−5
or
this --> 2−10=−5
***they both mean "-10 divided by 2" (negative 10 divided by positive 2)
- the numbers have DIFFERENT signs
- so the answer is negative!
4
Fact Families with Integers
Multiplication and Division
- We will use what we learned about multiplying integers to now divide integers
- if you know a multiplication fact of integers, then you also know 2 division facts
5
Example: We know that
−3×−5=15
Then we also know...
15 ÷−3=−5
and
15÷−5=−3
