Dividing Integers
The way of reading the dividing integers is:
- How many groups of __ are in __?
- How many __'s go into __?
Partitive Division - The making of groups or parts.
Quotative Division - Sharing with groups.
The quotient of the two integers with the same sign der of Operations with Integers

Chapter 2:
Multiplying Integers.
In multiplying Integers you need to know the sign rule and how to multiply.
Sign Rule.
Ex's.
When you have an even number of negative factors, the product will be POSITIVE.
eg. (-4) x (-4) = +16
When you have an odd number of positive factors, the product will be NEGATIVE.
eg. (+5) x (-4) = -20
Ways of showing how to multiply integers:
Positive x Positive = Positive: (+2) x (+3) = +6 , (2) x (3) = 6 , (2) (3) = 6
or
2(3) = 6
or
2 groups of (+3)
Negative x Positive = Negative: (-2) x (+3), remove 2 groups of (+3)
Negative x Negative = Positive: (-2) x (-3), remove 2 groups of (-3)

Chapter 1: Grade 7 Integer Review:
Integers are "negative" and "positive" numbers. They can be represented as integer chips or on a number line. You get a "zero pair" when you have a negative and positive of the same number, example: -3 and +3 make 0.
Adding and subtracting integers:
(-3) + (+9) =
owe 3 have 9= +6
(+7) - (-9)
have 7 owe 9= 16
Chapter 2 multiplying integers:
Sign rules: When you have an even number of negative integers the answer is positive.
When you have an odd number of negative integers the answer is negative.
(3)x (7)= 21
3 groups of positive 7 the answer is positive 21
+++++++ +++++++ +++++++
(-4) x (+2)
remove 4 groups of positive 2
++ ++ ++ ++ = -- -- -- --

- How many (c)'s go into (d)?
(+9) ÷ (+3) =3
Partitive Division - The making of groups or parts.
(9) ÷ (3)=

Quotative Division - Sharing with groups.
The quotient of the two integers with the same sign is "Positive".
The quotient of the two integers with the different sign is "Negative".

Albert's Term 2 Reflection
What I learned in term 2 is about volume, surface area, and percent. Volume is a measurement of 3 dimensional space and tell how large it is, we got to learn to find the cubic squares in shapes. The surface area is the surface of the 2 dimensional space, the shapes we learned to find the surface area is a triangular prism, rectangular prism, and cylinder. What we learned about percents is about how to convert a number into a percent then into a fraction and decimal.
What I find easy to do is doing the test because I learned about it before. What I struggle in is remembering the formula for finding the surface area of a triangle because I used the wrong formula. In the next term I will try to work harder and study for a test.

Chapter 1 : Great Book Of Integers Review
In integers, when adding both positive and negative with the same number they will cancel each other out making the answer a zero.
In Integers you can have zero pairs.
Zero pairs is when you have positive and negative number that is the same.
ex. (+9) + (9-) = 0
I prefer using standard form because its easier to answer and easy to understand.
ex. +9 + -1 = -10
Sign Rule:
If there is even number of positive the product will be POSITIVE
If there is a odd number the product will be NEGATIVE.

Ivorys term 2 Reflection
In term 2 we learned about percent,surface area and volume.
We learned how to find percents and represent them as fractions and decimals. We also learned to show percents on a 100 grid and how to use percent with tax prices.
We learned how to find the surface area of rectangular prisms, triangular prisms and cylinders. To help us we made nets and 3D shapes to help us find the surface area.
In volume we learned how to find the cubic squares in a shape.
I found it very easy to do all this, my tests were nearly perfect without studying but I never did any homework. In class I would help others to understand what they needed to do but I hardly did any textbook work. I didn’t do the blog, I didn’t scribe, I didn’t comment and even though I’m doing it now, don’t expect me to keep doing it.
Next term I’m probably not going to be any different with my work habits, but truthfully, I hardly know myself so maybe I will. Old habits die hard.
