### Jieram's Great Big Book of Integers

Chapter 2
Grade 7 Integer Review

An Integer is what is more commonly known as a Whole Number. It may be positive, negative, or zero, but it must be whole. You can use Integers on a number line or using integer chips.

Integer Chips

If you're Subtracting something that isn't there use a Zero pair.

1) -4 - (-8) = +4
2) -7 - (-9) = +2
3) -3 - (-7) = +4

Number Line

Chapter 2

Multiplying Integers

Sign Rule
If the product of two integers with the same sign the answer would be Positive
Example: (+2) x (+5) = +10

If the product of two integers with the different sign the answer would be Negative
Example: (+2) x (-5) = -10

Chapter 3

Dividing Integers

Partitive Division is when you divide it into parts

Qoutative Division - Sharing with group

Chapter 4
Order of Operation with Integers

To solve problem like these:

-24+[(-8)/(+4)]=

(+5) x (-3) + (-6) ÷ (+3)=

You'll have to use BEDMAS
Brackets, Exponents, Division, Multiplication, Addition, and Subtraction
