Here’s what we learned today – we’re just applying the distributive property again, but it’s important that we practise the skill. I’m posting this a bit late, but remember that you should have spent 15-20 minutes on these tonight.
When each outcome in a sample space is equally likely,
for each .
For any event ,
We often say something like, “We get the probability by counting the number of ways the event can happen and dividing by the number of ways anything can happen.”

We’ve learned how to multiply monomials, such as:
(page from that day: 06 – Multiplying Monomials)
We’ve learned about the Distributive Property of Multiplication over Addition:
Today we worked on Fractice and then practised adding and subtracting polynomials, such as:
Here’s the homework for tonight: 08 – Adding and Subtracting Polynomials
Tomorrow we’ll be multiplying polynomials by other polynomials. Should be fun :)
We started to talk about probability today. We saw that playing the lottery doesn’t seem like a great idea, and we learned a bunch of notation and terms. Here’s a summary, along with a couple of things we’ll be starting with tomorrow.
We started learning about the Exponent Laws today (we didn’t quite finish). Here’s a note to go along with our learning today (including a bunch of practice work).
We spent some time looking at parts e) and f) from your first quiz, then we practised a bit more substituting-and-evaluating. Picture Day took up the last half hour of class, though, so no homework tonight :)
