3(x-1) = 5x +3 -2x
3x -3 = 5x +3 -2x
3x -5x +2x = 3 +3
0x = 6
x= 6(1/0)

Richard Catto — Yes, yes, I got the sigma now. Thank God for Excel, right? OMG. I just went to those links. Induction? Now my eyes are bleeding! What are you doing to me? Oh, yeah. I started this.

If you want to really do your head in, you can find lots of crazy math arithmetic series summation proofs by searching. Here’s two I found:

I also hope you haven’t forgotten l’Hôpital, because that would be tragic. Haha.

Richard Catto’s last blog post..Driving Miss Daisy

Ricardo Bueno — OK, but don’t be mad at me if her head explodes.

Jay — Oh no! More leakage! I’m laughing at your latest post. What’s with all the cheese posts these days?!

Jay’s last blog post..Something special in the cheese department

I just wanted you to know that you *really* cracked me up with this one! I’m going to show problem to Johanna and see what she comes up with Hehe…

Ricardo Bueno’s last blog post..Social Media Is…

Fancy’s last blog post..My kid is pretty cool, sometimes

Lee — Yes, but you did it anyway and that makes you an egghead. Take it as a compliment!

BabaBooey — God, I thought you said “magnets.” Which didn’t make sense to me, but neither does “magenta.” Oh, my head hurts again. Remind me to never do another math post, will ya?

Shieldmaiden96 — At least you have bad poetry to show for your efforts now. That’s more than anyone can say for algebra, no?

Richard Catto — Huh? Wha? n squared plus n divided by 2? Stop hurting my head!!!

Elle — I shall look for your eyeball. Will you look for my brain matter? I think some leaked out when I wrote this.

Joe — I couldn’t agree with you more. Pie is the solution to all math problems.

Steve — I suspect that’s what she did. It takes a truly smart teacher to check the answers of his or her students, wouldn’t you think? Oh, man. People! Stop putting equations in your comments. My head’s gonna explode!

Steve — Listen, pal. I said no more equations! I’m not even looking at that, much less try to digest it, and you can’t make me.

Emma in China — You and most everyone else here. You’re in very good company.

lala — Yeah, I never thought I’d get asked to do algebra either. But now I went and confirmed to my husband that I know something about it. Stupid, stupid me.

Daisy the Curly Cat — Yes, but you can count your legs. I saw you do it on your blog today. So you are a little bit smart with math.

Jaffer — That girl needs a blog.

Jeff — I bet you think I really have more cats, but never talk about them for fear you will mock me mercilessly. You’ll never know.

Dan Brantley — Funny! That’s alright. Lots of us stink at lots of things and some of us just stink. What’s that smell?

Tiggy — n is for nevermind, just think of puppies and cotton candy.

Chris — I’m thrilled I was right about the equation. I did take the student’s grade level into consideration. I figured she’d never see weirdo numbers until college. Algebra was fun for me in school, but now? Not so much.

kpasa — That’s why we have two sides of the brain. One for math and one for everything else. If you think that picture is different, wait til you see the one I plan for Thanksgiving. Glad you stopped back and got caught up!

Carla — I cracked up loudly when I read your comment. Oh, please do write about that experience. I’m seeing lots of zits and braces.

Grant — A-ha! An expert among us. Yes, please do run it by a mathematics professor if you think of it. I ran it by an economist and he’s the one who thought perhaps irregular numbers might make it solvable, but even he was doubtful. Oh, and you’re an egghead. (And GO Phils! I’m sorry they lost their last game, but it ain’t over yet!)

Babs beetle — Oh, you’re so funny! Save yourself. Get in a happy place, curl up with a book and a warm kitty and forget this ever happened. I swear I’ll never post math again.

Regan — I think you need to hold an online class for those of us who’ve been away from math for more than 20 years. Can you swing that?

klc — Now, missy. Go back and check your work. You removed the -3 and the +3 from either side of the equation. Fatal error. Of course, math is easier if you just remove numbers that get in the way. English majors rule!

JD at I Do Things — Indeed. Pie solves all of life’s problems. Chocolate French Silk pie sounds like the perfect antidote to this post. (scribbles something pie-ish on shopping list)

Preston — I bet you’d be surprised at your residual math prowess. I couldn’t believe I even got an answer while still on the phone with my husband. It surprised me. Yes, this was a fun and thinking post. But I promise I won’t have very many more cerebral posts. I can’t take it.

brooke — Smarty pants! You’re probably learning this stuff right now, aren’t you?
