Krizna's Great Big Book of Integers

Chapter 1

This is what we did in class.
We learned how to solve different kinds integer problems,
We learned how to solve it in different ways we can use :

We learned about zero pairs too,
A zero pair is a number with answer of zero
"when subtracting something that isn't there use a zero pair"

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















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











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
