**Chapter 1 Grade 7 Integer Review**

(+4)-(-4)

You have 4 (+4) and you owe 4 (-4)

(+4)-(-4)=0

This is a zero pair.

Make zero pairs

-6=+6

-10=+10

-19=+19

-16=+16

-11=+11

-14=+14

-63=+63

**Chapter 2**

(+2)x(+3)=+6 or two groups of (+3)=6

(+2)x(-3)=-6 or two groups of (-3)=-6

(-2)x(+3) (+3)x(-2)=-6 or remove 2 groups of (+3) use zero pairs

(-2)x(-3) or remove 2 groups of (-3)=6

sign rule:

Even:when you have a even number of **negative** factors the product is positive.

Odd:when you have a odd number of **negative** the product is negative**Chapter 3****Dividing integers**

There are 2 types of division.

Partitive division:

Partitive division is **making parts.**

6÷2=3

6÷-2=-3

Quotative division:

Quotative division is **sharing your total, with groups**.

(-6)÷2=-3

multiplicative inverse helps when you cant explain how to divide:

6÷(-2)**Chapter 4**

How to solve this question,

(+5) x (-3) + (-6) ÷ (+3)=

(+5) x (-3) + [(-6) ÷ (+3)][division]

[(+5) x (-3)] + (-2)[multiplication]

(-15)+(-2)[adding]

=-17
