### Kristopher's Great book of intergers

CHAPTER 1

1) -6-(-4)= -2
2) -10+6= -4
3) 6-7= -1
4) 6-7+2= 1
5) 14-(-3)= 17
6) -3-(-7)= 4

7) -3-7= -10

8) 3-7=4

9) 3+7= 10

10) -3+7= 4

CHAPTER 2

(+2)x(+3)=(+6) 2 groups of (3), +++ +++=(+6)

(+2)x(-3)=(-6) 2 groups of (-3), --- ---=(-6)

(-2)x(+3)=(-6) remove 2 groups of (3), --- ---=(-6)

(-2)x(-3)=(+6) remove 2 groups of (-3), +++ +++=(+6)

CHAPTER 3

What is Partitive Division? Partitive Division is where you know the total number of groups.

6/2= 3

-6/(-2)=3

Multiplicative inverse is when you use a multiplication to figure out your quotient.
6/(-2)=
(-2)x(-3)=6
(-3)x(-2)=6
that means 6/(-2)=(3)
SIGN RULES
In a division question with an even amount or no negative signs the quotient will be positive.
EX: 6/2=3 or -6/(-2)=3

In a divition question with an odd number of negitive sign the quotient will be negative.
EX: -6/2=(-3) or 6/(-2)=(-3)

CHAPTER 4

Order of Operations with Intergers
[(5)x(-3)]+[(-6)/(3)=
(-15)+[(-6)/(3)]=
(-15)+(-2)=(-17)
