I finally figured out Order of Operations!!
All this time, and the order of operations was a mystery to me. I almost always got them wrong, and when I didn't, I had no idea how I did it.
You're kind of forced to face your own demons and step waaaayyy outside your comfort zone in order to help your child. I've learned more about grammar than I even knew existed. (Shh. Yes, I'm a writer, but I didn't know what it was called when I left a participle dangling!)
But now I know that and the order of order of operations:
Multiplication or Division next, worked left to right if there's more than one.
Addition and Subtraction next, worked left to right.
I know, I know. I'm probably the only grown-up out there who did NOT know how to work these problems, but there it is. Yay for me!
