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)



Grade 7 Integers.




(+) 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.
