### Brandon's Great Big Book of Integers

Chapter 1

Questions for class
-8 - (-4) = -4
-10 + 8 = -2
8 - 7 + 2 = 3
17 - (-3) = 14
- 5 - (-7) = 2

- 2 - 5 = -7

3 - 7 = -4

5 + 5 = + 10

-5 + 6 = - 1
Chapter 2
Multiplying Integers
(+4)x(
+2) = 8

Make 4 groups of positive 2

Make 4 groups of negative 2

(+4)x(-2) = -8

(-4)x(+2) = -8
Remove 4 groups from positive 2

(-4)x(-2)= 8

Remove 4 groups of negative 2

Chapter 2

Dividing Integers

Even = When you have a even number of negative factors your product is positive.

Odd = When you have a odd number of negative factors your product is negative.

Partitive Division - when you use groups to find your quotient.

6 ÷ 2 = 3

(-6) ÷ (-2) = 3

Quotative Division - Sharing numbers in groups

(-6) ÷ 2 = - 3

Chapter 4

Order of Operations

(+6) x (-2) + (-6) ÷ (+2)= ?

1) Always do multiplication and division first
2)
Put square brackets around (+6) x (-2) ex. [(+6) x (-2)]
3)
Put square brackets around (-6) ÷ (+2) ex. [(-6) ÷ (+2)]
4) Solve (-12)+(-3) = + 15
