### Derec`s Great big Book of integers

Chapter 1 Grade 7 integer review A Zero pair is when you have a positive and a negative which when added creates 0

ex. (+8)+(-8) (+18)+(-18) (+22)+(-22)

(+) Positive means you have.

(-) Negative means you owe.

() The brackets are like training wheels.

The standard form of intigers is +5-5.
The pure standard form is 5-5

Chapter 2 Multiplying Integers

If the brackets are touching, you have to multiply

ex. (+5)x(+4) or (+4)x(+5) <- Standard Form.

You can use repeated edition to solve/answer.

ex. (+4)+(+4)+(+4)+(+4) or (+8)+(+8)

(+3)x(+5) =(+15) or 3 groups of 5 is 15

If the first number is a negative,you need to multiply the two numbers and then you have to remove .

Chapter 3 Dividing Integers

(+10)/(+2), 10/2, how many 2 are in 10?, how many 3's go into 10?

Paratative Division is when you divide into a part

Chapter4 Order of Operations with integers
You can solve (+4)x(-2)+(-8)/(+2) byy using BEDMAS.
(+4)x(-2)+[(-8)/(+2)]=(-12)
[(+4)x(-2)] + (-4)=(-12)
[(-8)+(-4)]=(-12)

1. Good job, Derec! I liked the way you explained your knowledge, but next time add some color to the important things.
