one other thing...the only way the equation can be interpreted to be (48/2)(9+3) is if the fraction (48/2) is WRITTEN smaller than what's in the parentheses. Example
48/2(9+3)=288

I am reading the equation AS IS--algebraically.

There r many ways to write this equation that changes the interpretation depending on school of thought.
 
but it's written a specific way in the original post, which should leave no room for misinterpretation LMAO

Yes but our varied schools of thought gave rise to different results. Honestly, even if the notation stays the same, general interpretation sometimes changes. Meanings of words or usage changes. If humans create it, it won't be perfect. This is y older calculators may have been coded to understand this problem different than what is common in search engines and other modern tools.

I knew u had good points last night but I was just messing around at that point. Look at my original posts and u will find i said the same thing I am saying now.

As I said with my first post, this is not debatable but worth the fun.

i am saying it is the same because once you get to the MD level of PEMDAS (would be the same with AS as well), he states that you move from left to right.
they are the same until you add a level of division to the problem...
b/(c+d) x e-f is very different from b/e(c+d)-f.

let's say b=1, c=2, d=3, e=4, f=5
the 1st equation = 4/5-5 = -21/5
the 2nd equation = 1/20-5 = -19/5
 
So why does math.com have 1/2(5) =2.5
in the ex
x = 1/2 ($5.00) - $2.00
x = $2.50 - $2.00
x = $0.50 or fifty cents

I think the answer is 288 depending on the origin of the question. If was a problem thats not attach to in real life example, then its 2.


Im going to email them right now.

The people u r going to email r no smarter than u. Do what makes sense. If the results of the problem (especially dealing with $) don't make sense then revisit your process.

We have no context for the problem posed in this thread and no no the author's school of thought on the notation. I believe the common practice these days is to roll with PEMDAS when in doubt.

What the hell are you talking about? Why are you over analyzing this shit? It's written THIS way. Being written THIS way, it has only one answer. Trying to Socrates this shit is almost worse than not having the right answer.

Fam, fallback. I'm explaining y this is a heated debate all over the Internet. If it were as str8 forward as u think, it wouldn't be an issue. I'm a scientist but accept the flaws in it due to those that created it. Humans. Simple as that. When these problems arise, which they do more than u might think, u roll with what makes sense in context.

I will fall back. I am an engineer and a got a physics degree also. It's just, that I learned a long time ago to pick my battles on this board. There was a time when I would come here and try to explain things (when I was in a position to) to these negros on here. You will reach a few, but always remember that there is an endless line of dumb-asses that you won't reach. I respect you for being willing to help.
 

right at the 5 minute mark, he goes into addressing this specific type problem.

i have my daughter using this program. it has helped immensely.




and for the record, if you copy and paste the OP's original equation, this is how google reads it.

516309


Seeing is one thing, listening is another. Loop from 3:06 - 3:11. Dude says...

"we have no parentheses,
parentheses look like that,
those little curly things around numbers"

numbers imply "more than 1"
number (no 's') is singular...aka no parentheses.
 
Peace,

I don't know whether to :smh: or :lol: at this thread.

By the way, you should have offered more than two options in the poll. Half of the correct responses are going to be guesses.
 
Blasphemy!!!!

no really... these niggas are HORRIBLE at math tho. ALEX is really making me sad. come on teach:smh:

you are doing this if you get 288 as your answer

(48/2)(9+3)=288. it's the only way to get 288 but if you respect trip O's you get 48/(2(9+3))=2. everything on the right side of the division sign must be resolved first. the parenthesis is IMPLIED by the division sign. A DAR DAR :smh:



now had there been an additive or subtractive sign between the 2 and the numbers in the parenthesis you can resolve them independently and then combine them.....

i genuinely do not understand your point. of course your equations are different, you wrote them differently. can you make the point using the original joint..? Please understand -- i am no math head. I knew about the khan academy video because i am relearning algebra for my 11 year olds sake and i just went through that last week.

Damn, just got on here and the first thread is this. I cant believe that it got 32 pages.:smh::smh:

its 288

You just said that calculators are not capable of performing order of operations. That is blasphemous. If you have ever used any typical programmable graphing calculator you would know this. I'm not talking about a weak ass scientific calculator. I'm talking Ti 82/83/89/92. There are many others, but these are the ones I remember, because I have all of them. The 89, differentiates, integrates and a 1000 other things. All which can't be done without algebra, which can't be done without being capable of performing order of operations.

Can we settle this once and for all...

48÷2(9+3)

48÷2(12) Take care of what's in the parenthesis first. Now they just a multiplication operation.

48÷2(12) Because multiplication has equal priority as division you work from left to right.

48÷2*(12)

24*(12)

288

End thread!

you silly ass negro the last calculator i used in a math class was a ti-92 and no it DOES NOT perform order of operations of scientific notation or otherwise. ask ANY computer programmer. in almost every instance of using those calculators i GUARANTEE you had TO CREATE BRACKETS AND PARENTHESES that did not exist in the original equations in order to make the calculator perform the order of operations. the calculator recognizes PARENTHESES but no, it does not respect order of operations. smart guy
 
Distributive property of multiplication over addition. Early Algebra problem.

The distributive property of multiplication CLEARLY states that the 2(9+3)
is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive
property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of
the parenthesis follows the distributive property of multiplication and must
be factored and simplified before performing any other operations on it.
You do NOT compute this expression from left to right until you use Algebra
to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (2*9 + 2*3)

Which leaves us with

48 / 24 = 2

Answer = 2.

Lastly for those using Google or any other online calculator.
These do not understand many theorems or properties so you must explicitly
explain what you mean. There is a difference between 48 / 2 * (9+3) and
48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second
reads 48 / (2*9+2*3). Be very careful with your signs.

Yes nigglit, there are times when you have to add parenthesis in order to make sure the calculator interprets what expression you are trying to evaluate. That does not mean that the calculator does not perform order of operations.

Say you want to calculate this...

1+2
------
3+4

We don't put this in like this...
1+2/3+4
Because WE KNOW the calculator WILL perform order of operations and perform this operation...
1+.667+4
Which is not the same as what is above which we know should be handled like this...
(1+2)/(3+4)
Which is...
3/7 right?
When we see this...
1+2
------
3+4
Those who know what we are doing, really see this...
(1+2)
--------
(3+4)
The we know those fuckin parenthesis are there. We don't write them, but we damn sure type them in. Why? Because we know that the calculator WILL PERFORM ORDER OF OPERATIONS. And in this case...
1+2
------
3+4
The calculator performing ORDER OF OPERATIONS would fuck our answer up. DUMMY!
In the case of the original problem...
48÷2(9+3)
This is not an issue because the calculator performing ORDER OF OPERATIONS is not gonna fuck up our answer. DUMMY!

I can see what you were trying to say, you just didn't say it right. We add brackets and parenthesis to keep it from performing order of operations, not to force it.

Think about what you mean and say it right next time dummy!

Real talk, you know ain't really no dummy. You know how we bang on this board though.
