5. Learning Goals
LG 703: Students will be able to apply and extend previous understandings of operations to multiply and divide rational numbers.

6. What are we doing today? Today I am working with integers.
So that I can divide integers with same and different signs.
I’ll know I’ve got it if I can accurately determine the product of the following expression:

7. Let’s Review Multiplication Rules
Multiply the integers
Count the negative signs to know if your answer is positive or negative.
Even number of negative signs = Positive Answer
Odd number of negative signs = Negative Answer

8. The Rules: Same as Multiplication!
Division can be written in two ways:
÷ or
Fraction (top divided by bottom)
We call the answer to a division problem a quotient
For 2 factors:
Like signs = POSITIVE
Unlike signs = NEGATIVE

16. An Important Note What if you’re given a problem like this? 10 – (-8)-2
Order of operations tells us to do division first, but in fraction form, we do everything on top first. 18 -2
The answer is -9

17. Exit Slip
