You also do addition and subtraction at the same time. They are essentially the same operations since you are actually adding negative numbers or multiplying its inverses.

How do you put an elephant in a refrigerator?

EDIT: Also, my answer for that works too. >.<

Take out the giraffe, put in the elephant. XD

EDIT: wow, ninja'd. xD

Still, the purpose was to obfuscate rather than to elucidate.

It is intended to "trick" people by way of technicality. Whereas if you're actually using math for anything worthwhile you'd better be as clear as possible. If there's any doubt as to clarity, use parentheses.

I still hold it is a very bad way to write a math problem.

this*999/3(110+1)/1/3

HOW MUCH THIS?

My calculator says 0.

Also, typing "this" brings up asind(tand(0)).

111^2*this

The answer to Wilson's "proof" a couple pages back is a division by zero. I don't think anybody actually said it yet.

Relevant:

Also, I actually don't think this is obvious at all but I felt like posting it

Let S be the sum from 1 to n of 2^k
EDIT: n is actually infinity

S = 1 + 2 + 4 + 8...
S = 1(1 + 2 + 4 + 8...)
S = (2-1)(1 + 2 + 4 + 8...)
S = (2 + 4 + 8...) - (1 + 2 + 4 + 8...)
S = -1 + (2-2) + (4-4) + (8-8)...
S = -1

S = (2 + 4 + 8...) - (1 + 2 + 4 + 8...)
S = -1 + (2-2) + (4-4) + (8-8)...
S = -1

let me fix that for you:
S = 1 + 2 + 4 + 8...
S = 1(1 + 2 + 4 + 8...)
S = (2-1)(1 + 2 + 4 + 8...)
S = (2 + 4 + 8...+2^(n+1)) - (1 + 2 + 4 + 8...+2^n)
S = -1 + (2-2) + (4-4) + (8-8)...+2^(n+1)
S = 2^(n+1)-1

It only gets weird if n --> ∞, where there is no "last term" that isn't cancelled out.

[cry4eternity]

Oh derp. I meant to say infinity.

.999... = 1
or .999... ~ 1

My favourite to do during a conversation of any sort is this one:

How many fingers are on one hand?
How many fingers are on two hands?
How many fingers are on ten hands?

It works really well if you show your hand(s) while asking

This one's tough. I know of -

Brazil and Portugal

I bet there's only 4 countries like that anyway

[One Winged Angel]

I'm stuck on four...fucking hell, I'm not going to be able to sleep until I get that fifth

If there isn't one, I'm going to be incredibly rattled

edit: what I have

Brazil, Israel, Nepal, Portugal

edit2: Rubix if there isn't a fifth, I'm going to castrate you

edit3: yeah I don't care anymore, took me less than two minutes to come up with the first four but can't scrounge up a fifth with an additional twenty minutes, gay

Interesting. Here in australia in the early 90's we were taught BOMDAS or BODMAS (essentially the same thing)


An old one I like is this...


A A A A ? A A A A A A

What is the missing letter?



Edit: Rob, the fifth is Senegal ;D

Lol, I remember seeing this somewhere, so I'll give other people a chance first x3

Here's another easy proof thing:

Believe it or not, Square A and B are the same color.
