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

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:

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

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

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
