Headfuck!

I'm not what you'd call thick, but my particular type of intelligence has GAPING gaps and vast blindspots......I present here for your amusement, the following conundrum, first told to me by my granny, now sadly (for us, she'll be having a ball wherever she exists now) departed......in all my years I've never fully bent my head round this, I've even resorted to computers and failed.

Obviously I've updated it a wee bit. the original being old sounding in the 70's.

Two sisters,Mary and Sadie go to their local branch of Dixons to get Sadie's granddaughter one of those mp3 player things. They spy a nice looking one for £30, and since Mary is sort of the wee girl's favourite great aunt, and since they're both poor pensioners, they decide to go halfers on it. Each of them stumps up the £15 and they depart with the player. As they leave the shop the manager approaches the sales gimp and says "did you charge them £30 for that? they were meant to be reduced this morning, you didn't update your till!!!!". In an act of kindness not normally asociated with this fool-from-cash-separation emporium, the manager orders the gimp to give chase and return overspent fiver to the auld dears.

The gimp scoops five pound coins into his sweaty paw and bolts out the door. Just before he catches the ladies, three pound coins slide out of his greasy mit and plop straight down a drain grating.

Being too lazy to go back, and thinking the old girls will never know any better, he runs on up to them and gives them a pound each, saying that it had been reduced by only £2.

The thing is..... this means they paid £15-£1=£14 each=£28

but £28+£3 down the drain=£31!!!!!!!!!

go figure.

(cept Nora, she'll probably know and give me an inferiority complex)

The actual cost is £25 not £30, so £28 - £3 = £25.

Or put into English, the old dears have coughed up £14 each. That is £28 in total. The £3 that was lost is part of that £28, hence the subtraction not addition.

EDIT: Do I win £41?

So I had the 3 quid in the wrong logical place all this time?

It will take time for my brain to accept this, AND the fact that I was outsmarted by a 60+ farm girl

It actually baffled one of my maths techers, but the same idiot suffered a mental seizure when presented with this pathetic "proof"......

x=0 y=0 so x+y=0 2x+2y=0 so x+y=2x+2y

now divide by x+y

x+y=2x+2y

x + Y

and you get

1=2

so there's all of maths fucked right there!

After ruining that teacher (the Add Maths teacher I may point out), I tried it on my regular maths teacher, who promptly kicked me in the arse and scrubbed it off the board.....then said "hang on, write that up again, I'm gonna give it to my first years as a homework"

That's easy Steve. It's a D/0 error. Nice Thread topic though.

Indeed!

Is that one real or a spoof? I've seen some good Turing questions that would fail half the human race pretty quick.

It's ironic you posted trig shite.The idiot teacher in question, while "teaching us" about trigonometric identities, started yelling at the whole class cos none of us (including the ones so geeky they made me look like a hooligan) could do a homework on them. He called us idiots and we demanded he demonstrate how they worked...... He did the first question, which we'd mostly got right anyway, then with much hmmmming and haaaammmmming and hawwwwing he declared his solution of Question 2 complete. About 8 hands shot up....."sir, why is MINUS cos-theta magically transformed into Plus cos-theta on the next line?"

You know in sci-fi when some machine or other is faced with a terminal logical impasse and it smokes, shakes, spins and ultimately fails.....he did it, right in front of us....a complete mental shutdown.....he went quiet....went back to his desk to look at the teacher's edition of the textbook...then started working on the rollbook, and suddenly after five minutes or more, stood up and announced that we'd spent too much time on pure maths and needed to do more mechanics and statistics.

THAT'S why standards are slipping.

Here's a cracking god read for you Steve, Euclid's window

and a simple game, Dogbone

Been a while since I read a book on science actually. Which reminds me, I need to get another copy of James Gleick's book on chaos theory, now that IS a headfuck!

The game looks like an interesting test of how one visualizes numbers. I'm a borderline Asperger's case so it's a bit easy for me , I must try it on others.

Another silly game http://combinationlock.com/

I wish I could remember the equation, but some years back my calculus teacher showed us how 3=1 by the use of "i"(otherwise known as the square root of -1). Derivatives always gave me headaches

That kinda reminds me of a shirt, that I will recreate what I saw on said shirt here [this time with THIS equation]...

:p

Just use a credit card instead.

:p maybe you should answer that question. cause i already answered it. so what do you not understand?

Indeed!

Indeed! I'm just saying Cambo's equation reminds me of a shirt I saw on someone that said What part of [insert complex math equation here] do you not understand?

Am I the only NOOLer who is just misunderfookin'stood?

...never mind. I don't want to know.
