### Mark's Great Big Book of Integers

Chapter 1 Grade 7 Integer Review

If something
is not their, use a zero pair!

Standard - 7 - (-3)=

Chapter 2

Chapter 3

Dividing Integers

Partitive division is creating groups of numbers.

(-6)/(-2)= +3 (-6)/2= (-3)

Quotative division is sharing numbers in groups.
(-6)÷2=

Multiplicative Inverse - Rewriting a division question to a multiplication question. It helps you when you cant find a way to use quotative division or partitive division to solve an answer.
Example :
6÷(-2)=(-3) Since I can not share 6 with (-2) groups, I use the Multiplicative Inverse
(-2)x(-3)=6
(-3)x(-2)=6

Chapter 4
Order of Operations with Integers

To solve (+5) x (-3) + (-6) ÷ (+3)= you would have to use BEDMAS
first you would divide the answer using square brackets.
Remember, square brackets are the first thing you do.
From then, you would keep shortening the question until you get an answer
Ex. (+5) x (-3) + (-6) ÷ (+3)=
[(+5) x (-3)] + [(-6) ÷ (+3)]=
(-15)+(-18)=
+33
