To us younger types, it doesn’t require much thought. But to an older student who hasn’t had algebra in X years or ever:
((A-B)/B ) does not equal A-B/B
Two students in the night class had the same difficulty with this concept. While I do have some compassion for them, I lose a lot when the book clearly has it in the first form of ((A-B)/B) and instructed the students to type it in as so.
Order of operations isn’t a suggestion, it’s a rule.
EDIT: It’s now “a lot”
I just had a radical thought. One that explains why LOST happens. I’m putting it after the break, so if you feel froggy, jump.
So, I’ve decided something.
I’m committing to something ZOMGLOOKOUT.
There’s no longer going to be the crazy bitch group on my cellular device. As of now, it only holds one number. And no, you who called me tonight, it wasn’t yours. Yours will be added. The first number is there because she could be. The first number I’m adding tonight is going to be an ex-officio into the group. Cold Hard Bitch is our thing. Our inside joke. The reason I’ll still have to look down at the group to pick it up instead of just flipping the phone open and listening for the voice. You who called me tonight, yours will be next then. Not because you are one, but to remind me that I have to be one to you. You brought it on yourself. And I’ve extended the olive branch of friendship, and that’s all I can allow you to take from me anymore.
Also, to one person, if you still look here, be safe in Milwaukee. I really want to call you to say that in person, but I’m too much of a cold hard bitch to say the other things I need to.
