We will be talking about the Order of Operations on Wednesday. Many of you are already familiar with this, so it may be a review for some of you, but that's okay! Fun, random fact: My favorite planet is Neptune.
So... what do I mean when I say "order of operations???" I'm talking about the order in which we solve a math problem. "Operations" refers to the math operations we use, such as addition, subtraction, multiplication, etc. There are very specific rules we must follow in order to arrive at the correct answer, and this order of operations should be used whenever you do math - not just when a problem says "Use the order of operations to solve." :) Another fun fact: Christmas lights make me happy.
We use the acronym "PEMDAS" to remind us of the order of operations:

**Notice that MD and AS are grouped together! We'll talk about why tomorrow!**
A great way to remember the order of operations is to remember "Please Excuse My Dear Aunt Sally" - the acronym fits this phrase. We're also going to talk a little bit about Aunt Sally tomorrow ;) Final fun fact: My TWO favorite movies are "It's a Wonderful Life" and "Interstellar."
Okay. Now that you've read a little preview for tomorrow's lesson, prepare for the drill by making sure you've read this post in its entirety and have found the three facts about Ms. J.!
