### Ivan's Great Book Of Integers.

Chapter One:

(+4) + (-2) = +2
Positive (4) Negative (2) = Positive 2
Have 4 Owe 2 = have 2
Standard Form : 4 - 2 = 2.

Making A Zero Pair:
An example of a zero pair is (+1) + (-1).
A negative and a positive can make a zero pair because it is oppisite from each other.

Chapter Two Multiplying Integers:
Sign Rule:
Even: When you have an even amount of negative factors, the product is positive.
Odd: When you have an odd amount of negative factors, the product is negative.

(+2)x(-3)=-6
2 Groups Of (-3)=-6

(+2)x(+3)=+6

(-2)x(+3)=-6
Remove Two Groups Of (+3)=-6

(-2)x(-3)=+6
Remove Two Groups Of (-3)=+6

Chapter Three Dividing Integers:
Sign Rule: If you have no negative or an even amount of negative signs in a division question, the quotient is positive.

2 Types Of Division:

Partitive Division:
making parts

EX.
6/2=3
6/-2=-3

Quotative Division:

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

Chapter Four Order Of Operation:

Brackets
Exponents

Division
Mutiplication
Substracting

(+5)x(-3)+(-6)/(+3). First you always follow BEDMAS, so division is first in the question, after you multiply, and do the adding.

EX.
(+5)x(-3)+(-6)/(+3)=-17
(+5)x(-3)+(-2)
(-15)+(-2)
