Chapter 1

(+4) + (-2) = +2

Positive (4) and Negative (2) = positive 2

have 4 and owe 2 = have 2

Standard Form: 4 - 2 = -2

Making zero pairs:

-16 = +16, -5 = + 5, +6 = -6, -2 = +2,

-10 = +10, +3 = -3, +11 = -11, -9 = +9

Chapter 2 Multiplying Intergers :

Sign Rule:

Even: When you have an even amount of Negative factors, the product is Positive.

Odd: When you have odd amount of Negative factors, the product is Negative.

(+2)x(-3)=

2 groups of (-3)= -6

- - -

- - -

(+2)x(+3)=

2 groups of (+3)= +6

+++

+++

(-2)x(+3)=

remove 2 groups of (+3)= -6

- - -

- - -

(-2)x(-3)=

remove 2 groups of (-3)= +6

Chapter 3 Dividing Intergers

Sign Rule:

If you have no negative or an even amount of negative signs in a division question, the quotient is positive.

There are 2 types of division:

Partitive Division:

Making parts

EX:

6/2=3

6/-2=-3

Quotative Division:

Sharing you total with groups

EX:

(-6)/2=-3

(-6)/-2=+3

(+5) x (-3) + (-6) / (+3) first you always follow BEDMAS so division is first in the question

after you do the multiplication and finally you do the addition.

example.

(+5) x (-3) + (-6) / (+3) = ( -17)

(+5) x (-3) + (-2)

(-15) + (-2)

(-17)
