**Chapter 1 Grade 7 Integer Review**

**Questions:**

-6- (-4)=-2

-10+6=-4

6-7-2=1

14- (-3)=17

**Multiplying Integers**

**This question is saying to add two groups of positive 3's**

**This question is saying to add two groups of negative 3's**

**This question is saying to take away 2 groups of positive 3's, I used zero pairs to do that.**

**This question is saying to take away 2 groups of negative 3's, I used zero pairs to do that.**

**Sign Rule ( negative signs )**

**Even= When you have an even number of negative factors the product is Positive**

**Odd= When you have an odd number of negative factors the product is negative**

**Dividing Integers**

**If you have no negative or an even number of negative signs in a division**

**question the quotient is positive**

**Ex ( 6**

**÷ 3 =2 )**

**6**

**÷3=2 <--- share 6 with 3 groups ( quotative division or sharing your total with groups )**

**6**

**÷ 3=2 <--- how many groups of 3 are in 6 ( Partitive division or making parts )**

**When you have an odd number of ( - ) signs in a division question the quotient is negative**

**sign rule for division**

**6÷2=3 <---- how many 2's are in 6?**

**-6÷ (-2)= 3 <--- if there is an even amount of negatives the answer is positive**

**(-6)÷2= -3 <---- if there is an odd amount of negatives the answer is negative**

**6÷(-2)=**

**-3 <---- if there is an odd amount of negatives the answer is negative**

**Order of Operations with Integers**

**(+5) x (-3) + (-6)**

**÷ (+3)**

**[(+5) x (-3)] + [(-6)****÷ (+3)]**

**-15+ (-2)= -17**
