Raelynn's Great Big Book Of Integers

Chapter 1 Grade 7 Integer Review:

Integers are natural numbers (positive or negative) or zero.


















Brackets are like training wheels.
For example; (-2) + 5 + (-7)

A zero pair are any of the same number that has a positive and a negative that will equal to zero. For example: -2+2 = 0

Examples of Standard forms:
4-5+6=5
-5-6=
4-5-7=

Questions and Answers:
-3-(-7)=4











-3-7=-10











3-7=-4










3+7=10










-3+7=4

The great Big Book of Integers Chapter 2:
(+2)x(+3)= +6

(+2)x(-3)= -6












(-2)x(+3)= -6












(-2)x(-3)= +6












Chapter 3; Dividing Integers

Partitive Division is to divide something into parts. An example for it is;

Sign Rule:

• The quotient of two integers with the same sign is: positive when even amount of "-" signs.
• The quotient of two integers with different signs is: add number of "-" means negative.

Quotative Division involves taking a set of size a and forming groups. (Sharing with groups)
eg.

Multiplicative Inverse to solve 6 ÷(-2)=;

Chapter 4; Order of Operations with Integers
We solve this using B.E.D.M.A.S. (brackets, exponents, division, multiplication, addition, and subtraction)

(+5)x(-3)+(-6)÷(+3)=
(+5)x(-3)+(-2)=
(-15)+(-2)= -17
