You got a horse in this race, bullitt? Do you have an answer to either the math question or the semantics argument? 'Cause, I haven't seen ANYONE proven right or wrong. Just a bunch of wind a'blowin' if you ask me.

I'll ask you all again: NO MATTER WHAT YOU CALL THEM DOES IT MAKE A DIFFERENCE IN A MATHEMATICAL EQUATION IF (THOSE THINGS] ARE CURVY OR SQUARED?

Other than an answer for that, just try to look bright and say 2 or 288.

kthx

tl;dr
288

In an arithmetic context, () and [] are usually equivalent. Having different ones is handy if you have more than one set nested, to clarify which matches which. I believe it's fair to say that {} are many times equivalent and just serve as a third "layer" of grouping when needed.

However, there are many contexts in math when there's a difference, or at least a specific role. For example, ranges of numbers: [0,6] indicates a range including the endpoints, 0 and 6, while (0,6) indicates that the endpoints are not actually part of the range. When you get into matrices and other crap like that, there are definitely ways to change the meaning by changing the typography. Context and definition of terms are critical.

oh no

standing-O for Undertoad!

brilliant!

no i just find em, it turns out this is a rapidly developing meme.

Holy fuck, you mean Flint didn't make this up? I figured it was up there with the card shuffling and the don't-use-zero.

That may have been true 40+ years ago (MAYBE), but not now. Don't get me started on fucking "theory."

What? I love zero. My 4yo knows to start counting arrays at zero.

[BigV]

orly?

What is your 4yo's answer to the thread title?

My apologies. For some reason I was thinking you were the proponent of the Get Rid of Zero thread.

you may be thinking of HLJ

So, how 'bout them Red Sox?

Well I don't believe that I'm wrong, so that can't be me that you're talking about, but since I have no more proof/evidence that I'm right I have nothing more to say about that. I did however have something to say about learned helplessness. Not my fault some are to dumb to get it without it being spelled out and turning into a bitchfest.

Sky, dear, I would contest that trolling is nurture rather than nature. And also since you are the one whaling into an argument in which you are not directly involved and you are the one calling names, that would rather put you under the bridge rather than me, no? I know how desperately you want to play Rhet in this scenario -and I see Bullitt is vying for the part too, but we already have a call out to someone's agent and are expecting them to turn up any minute.

PEMDAS

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. If you're not sure of this, test it in your calculator, which has been programmed with the Order of Operations hierarchy. For instance, typesetting this into a graphing calculator, you will get:

• 15/3*4=20

Using the above hierarchy, we see that, in the "4 + 2×3" question at the beginning of this article, Choice 2 was the correct answer, because we have to do the multiplication before the addition.
(Note: Speakers of British English often instead use "BODMAS", which stands for "Brackets, Orders, Division and Multiplication, and Addition and Subtraction". Since "brackets" are the same as parentheses and "orders" are the same as exponents, the two acronyms mean the same thing.)
