Whats the answer

April 10, 2011 @ 09:49:19
multiplication by juxtaposition and parentheses operations share the same hierarchy. quit arguing. fucking retards.

iheart asked a simple question. in this form: 48
April 10, 2011 @ 10:41:04
anything INSIDE the parentheses have priority in the order of operations. after that you read the equation from left to right.

48/2(9+3)

Do the parentheses
48/2(12)

left to right

48/2*12

24*12

288

trolls keep trollin. tards keep tardin.

blaiz, its fine to take it as 48/(2(9+3)), but technically, you cannot assume that. as i said, its simply bad form to do that. you need that second set of parentheses. i would never write an expression like the OP did. see here:

http://mathforum.org/library/drmath/view/57021.html

"...but do so by
having them evaluate an expression like:

6/2(3)

that is too ambiguous for any reasonable mathematician ever to write.
And no matter what the rule, we would still constantly see students
write things like "1/2x" meaning half of x, so we'd still have to make
reasonable guesses rather than stick to the rules."

6/2(3) is ambiguous

48
April 10, 2011 @ 16:49:28
they are the fucking same type of expression. you are an idiot. its clear that you dont do enough math in your life because anyone in my position in college would always ask the writer to clear a basic ambiguity like that.

not only that, what you said implies that you have poor critical reading skills. dr. math says 6/2(3) is ambiguous...you clearly said that "multiplication by juxtaposition" (as if its some sort of special multiplication) takes precedence over division. under that pretense, 6/2(3) is not ambiguous and would simply equal 1, but no, you would be wrong.

i go to collenge to! &)
and i does maths sometimes to!
April 10, 2011 @ 17:29:49
actually I'm a physics major and I've been doing long division before I could even read. eat a dick faggot.

relax dude.

99% of HB is asian, how the fuck is this even close in the polls? it's 288.

yo ♥♥♥♥♥ holla at me wen u doin differentiation, i cant do that basic math no more.
fuck u ♥♥♥♥♥.
April 10, 2011 @ 18:04:43
the answer is supreme
April 10, 2011 @ 18:18:28
knife fight or nothing, what say you, ucla boy?
April 10, 2011 @ 18:19:34
youre a loser. stop trying to validate your existence.
April 10, 2011 @ 18:21:06
you must be on some william shatner shit if you can get 288 from that.
April 10, 2011 @ 19:08:12
really though uclaboy, come see me when you've taken partial diff eqs at a more prestigious school and THEN try telling me that they're the same type of expression.

I'm quite embarrassed that I'd ever get this riled up over a math problem, but some dudes are just straight retarded.


the answer is 42 doe.

288. im asian!

2 my friend.


qft. And that's the order of operation. You must not be very familiar with the order.

Brackets, Exponent, Division, Multiplication, Addition, Subtraction

I grew up on PEMDAS so I multiply before I divide always. I got 2.


Lmaooo all of you guys following this, it's not your fault. You were simply taught wrong (or you didn't pay attention).
I was taught when doing PEMDAS (which is the same as Order of op ?),) when you get down to the M and D, you simply do whichever comes first in the problem. You do not always multiply first. Then, you get down to the A and S. You do whichever comes first in the problem, not automatically addition first.

Therefore, 288 is what you want.

please excuse my dear aunt sally

nice to meet ya, i'm math god

division and multiplication are ranked with the same priority as is addition and subtraction.

the way it is written, the answer is 288. distribution is not a rule, so you don't do that first before you do order of operations. you first do whatever is in the parentheses.

terms that are on the outside of the parentheses are not part of the parentheses. otherwise in 2(9+3)^2 you would multiply the 2 into the (12) before you did the exponent because parentheses come before exponents in the order of operations. therefore the (9+3) does not belong to the 2 in the original equation. it belongs to the 48.

the answer is 288.

Division is not always first. Whichever the problem presents from left to write (between division and multiplication) first, comes first. In this case it is division

you still didnt get rid of the parenthesis before you divided.


parenthesis here acts like multiplication,
and only the things inside the parenthesis go first, hence there is just a number (12), there is no more to do.
so..... division first

the 2 is not a part of the parentheses. all the work inside the parentheses is done. restart with order of operations.

Ahhhhhh. Okay, I get it.
