Robin's Great Book of Integers

Chapter 1

(10)+(-7)=3
have 10 and owe 7
Bracket: These are put in for us for training us for grade 8.

Zero Pairs: This when a positive and negative are put together to make a Zero Pairs

1+(-1)=0

Chapter 2
Sign Rules

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.

(2)x(2)=4
(+4)x(+4)=+16
3(5)=15

(3)(3)=6 *Standard form*

(3)x(3)
3 Groups of 3= 9

(3)x(-3)
3 groups of (-3)=-9

(-3)x(-3)
Remove 3 groups of 3

-

(-3)x(=3)
Remove 3 groups(-3)

Same as the other picture.

Chapter 3
Sign Rules

If you have no negative or an even number of negative signs in a division question, the quotient will be a positive.

There are 2 types of division:

Partitive division

Partitive division is making parts.

Example:
3divided by 2= 1

Qualitative division:

Qualitative division is sharing your total, with groups.

Example:
(-3) divided by 2= -1
