For the formula

what is the value of d when u = 3, v = 11 and t = 5?
http://www.mathopolis.com/questions/q.php?id=1134

Like I stated before where is the division sign? There isn't one.

The division sign is replaced by the slash making it a fraction and it is placed EXACTLY where the division sign was.

48/ 2(9+3)= 2

Actually, as per your link, the answer to our problem with be 288.

Following the example from mathopolis

Let:
u+v=48
t=12 <-as per (9+3)


48 x 12 = 288
2

From the above simplified equation, the only way we could get 2 as an answer is to multiply 48/2 to the reciprocal of 12, which we all know should never be done in this case.

That is what I was referring to, and past due it was...

I thought page 3 was the un-official limit

I felt it my duty to derail the thread. I voted 2, and everything after is too on topic!

Do what's in parentheses first. The answer is 2

48÷2(9+3)

48÷2(12)

48÷24

2



EDIT: Just realized there's like, 11 pages in this thread. My bad. :/

 

[yowanvista]

48÷2*(9+3) = 48÷2*(12) = 48÷24 = 2

The Standard Order of Operations should not be applied in this type of equation.
~ 48÷2*(9+3) = ???

In both the SOOO and PEMDAS rules, parenthesis are simplified first before proceeding.
Both rule simply the equation to 48÷2*(12) or 48÷2*12

SOOO vs Pemdas
~ SOOO will basically simplify it to 288.
~ PEMDAS will basically simplify to 2.

The resulting answer between both differs due to dissimilar order of mathematical processes.
~ Division is applied before multiplication in SOOO.
~ Multiplication is applied before division in PEMDAS

SOOO should not be applied in this type of equation since 12 is simplified from a parenthesis which involved addition.
The sum, 2 is proceeded using the PEMDAS rule since multiplication must be done first since the equation wuz simplified from a parenthesis. And since 48 wuz not derived from a parenthesis we proceed with multiplication before division.

Google simplifies 48÷2*(9+3) into (48÷2)*(9+3), perhaps since it follows the SOOO in any type of equation. The indication of parenthesis in 9+3 depicts that such must be multiplied to 2. The absence of parenthesis in 48÷2 tells that both is not to be simplified first and thus 2 must be multiplied to the sum of the parenthesis before division is to be proceeded.

Therefore, there is only 1 correct solution to the equation which is 2

Crap, I'm not even sure of what I'm saying... i'm still a kid....

I just cheated; I entered the equation into a graphing calculator, exactly like this:

48/2(9+3)

Calc spit out 288...

 

[kenmdotexe]

The calculator obviously simplified 48/2(9+3) to (48/2)*(9+3) and used SOOO to simplify the equation.

 

[boogieboy]

48 ÷ 2 (9+3)
24 (12)
24 x 12

= 288

when there's a bracket the values multiply

They're the same thing, and multiplication and division have the same priority. If they're the two operands to do in a sum, then you just work from left to right. To get the answer 2, you'd have to force the multiplication first and do 48/(2(9+3)).

And calculators that have a stack i.e. graphic calculators will give the result 288. Other calculators without a stack will give the answer 2. I gave an example of it a couple of pages back.

Wow. Don't overthink it folks. Go back to simple math.

48÷2(9+3) Once you do the work in brakets this question becomes
48÷2x12 At this point you follow the math rule that you do complex problems in the order they appear, which gives you
24x12= 288

No disrespect intended Everlong, but the rule, in PEMDAS, is not multipication first, multipication and division are equal in status. What you do is simply start from the left and go to the right.

That's what I said, and it's what I've always been saying that multiplication and division have the same precedence.

Just seen my last post has the quote messed up. I've fixed it, so it should look clearer to what I said.

 

[Zen00]

I just do the stuff in parenthesis first, then all the multiplication/division operations from left to right, like they taught me in college.

288

I hope there's no hard feelings Everlong.

None at all

Multiplication doesn't have precedence over division though and vice versa. If they're the only two operands left in the sum, then you simply just work left to right and in this case it would be divide then multiply, hence you get 288.

You get the A+.

Microsoft Math bears this out, as does Professor M. at CSU.

If you still don't believe it you must be using a Mac.
