Chapter 1 - Grade 7 Integer Review

Integers

- Number lines

- Integer chips

- Zero pair

- Positive and negatives ( + and - )

- "When subtracting something that isn't there, use a zero pair."

-6 - (-4) = -2

-10 + 6 = -4

14 - (-3) = 17

-3 - (-7) = 4

-3 - 7 = 10

3 -7 = 4

3 +7 = 10

-3 +7 = 4

Chapter 2 - Multiplying Integers

(+2) x (+3) = 6

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

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

(-2) x (-3) = 6

Chapter 3 - Dividing Integers

When you have an off number of negativ e signs in a division question, the quotient is negative.

If you have no negative or even number of negative signs in a division question, the quotient is positive.

Here is an example from our notes:

6 / 2 = 3

-6 / (-2) = 3

Quotative Division or sharing your total with groups.

Here is an example of what we did in class:

Chapter 4 - Order of Operations with Integers

(+5) x (-3) + (-6)/ (+3)

First, you make a box around (+5) x (-3) so it's 5 groups of negative 3.

That would equal -15.

Then, you put a box around (-6) / (+3)

How many groups of positive 3 would be in negative 6?

Negative 2.

So, -15 + -2 = -17.
