We’ve moved on to the next phase of the rational expressions unit: Complex Fractions. Don’t be intimidated by their name! These are expressions that involve “nested fractions,” meaning the numerator and denominator of the expression are both fractions (or a sum/difference of fractions) themselves.
Remember the basic process for simplifying these beastly expressions:
There are several videos online you could watch with more examples. I recommend this one and its follow-up here. The video posted here is also good. If you want more, search for “Simplifying Complex Fractions”
We started a mastery quiz in class today, and we will spend some more time finishing it tomorrow. This will end up pushing our traditional quiz to Monday, October 29. Make a note.
We did some more work with adding/subtracting rational expressions today, this time with polynomial denominators. The key thing to remember with these is that we can only obtain a common denominator through multiplying. We cannot add/subtract denominators. See the notes and the video below for examples.
We spent some time practicing adding and subtracting rational expressions in class today with a game of survivor. Your homework is a review of all four operations.
We will have a mastery quiz on Wednesday, followed by a more traditional quiz on Friday.
We worked with adding and subtracting rational expressions today, modifying the usual “lowest common denominator” process to accommodate monomial denominators. We’ll do some more practice with this on Monday.
We reviewed multiplying rational expressions today (remember: you must simplify before you multiply) and then introduced dividing rational expressions, which is really just more multiplying.
Our first day of new content! Today we looked at solving absolute value equations, and noticing how they always have two solutions. Check the links below for the notes, today’s homework assignment, and a video with a few more examples.

Our first lesson of the first unit was on the Order of Operations, and how it can go wrong if you’re not careful! See below for links to today’s notes and homework assignments, as well as a short video discussing the proper order of operations
