What Is The Answer To This Math Problem?

It's just misleading. I don't know anywhere in the math I've been doing for the last few years where something as elementary as (9 + 3) would be placed in brackets.

It's a mindfuck for me because I automatically think that the brackets is just a form where a number has been substituted instead of an unknown variable (ie (x + 3) => (9 + 3)) and so would be multiplying the denominator and not just a common factor.

lol, I get that you have never done any programming?

this is how equations are written in programming and there is only one way to solve it.










288.

Isn't the idea of programming to keep your code as simple and easy to read as possible?

If your intention is to make the answer 288, you'd put the term in the bracket clearly multiplying the numerator.

Yes you can. If you were to start with that second example and write it out in a single line it would be 48 / [2(9+3)] which gives clear dimention of numerator and denominator. if that were the case then the answer would be 2.

where as 48÷2(9+3) would be written as

48
---- * (9+3) = 288
2


You can try to interpreat it as many ways as you want, but ultimitly your back where u started with the ACTUAL problem. 48÷2(9+3)
And you and only interpreat it as it is layed out.

And as it is layed out, the answer is 288

and btw, to those that didnt realize it in math class; Perentasis or Brackets for some of you, ment that you do whats IN them first. Not whats next or attached to them


Edit: PEMDAS was jsut a acronym thought to us in elementry school when first starting algibra.
Please
Excuse

in an effort to help young kids remember the order

"as its layed out" I see it as 2 personally. 2(9+3) seems grouped together. If it were written 48 / 2 x 12, yeah then 288 makes sense. but im sure somebody pointed that out as well in the previous 5 pages

here

48/2*12 is the same thing as 48/2(12)

2(12) is nothing more then 2*12

As i said, perentasis means you do whats INSIDE it first. Not thats attached to it.

I believe the technically correct answer is 288, but it's written horribly.

I could ask what 2^2(2) is as an analogy. It's just a silly question.

In mathematics, reduction refers to the rewriting of an expression into a simpler form. For example, the process of rewriting a fraction into one with the smallest whole-number denominator possible (while keeping the numerator an integer) is called "reducing a fraction". Rewriting a radical (or "root") expression with the smallest possible whole number under the radical symbol is called "reducing a radical".

In linear algebra, reduction refers to applying simple rules to a series of equations or matrices to change them into a simpler form. In the case of matrices, the process involves manipulating either the rows or the columns of the matrix and so is usually referred to as row-reduction or column-reduction, respectively. Often the aim of reduction is to transform a matrix into its "row-reduced echelon form" or "row-echelon form"; this is the goal of GAUSSIAN ELIMINATION.


In Calculus, reduction refers to using the technique of integration by parts to evaluate a whole class of integrals by reducing them to simpler forms. A.K.A. Static Reduction

Therefore before any attempt at any equation you must first reduce the equation to its row-reduced echelon form which is 24(9+3)

simple as this

48÷2(9+3) = 288
48÷[2(9+3)] = 2

Yus, but in a normal problem you would never bracket the (9 + 3) there unless you either mean for the latter, or you've substituted a variable for a constant and that is an intermediate step. It is a mindfuck, and poorly written.

usually when it's written:
2(9+3)
i take it for 2*(9+3)
in college math classes we did the same on tests etc. so it wasn't a big deal first taking numbers in brackets together and later on multiply it with number x.

but i think it's just a troll thing.
so good going for discussing something like that for 5 PAGES!.

congratulations.

SOLUTION:
48/2*(9+3) = 48/2*12 = 24 * 12 = 288

Thank you for correcting me, I hadn't put in as much thought I should have. On a side note, those that were getting 2, here is what you did wrong,

48/2*(9+3) = 48/2*(12) not equal to 48/24 = 2

OPPS, my bad. Now I can feel like a tard for the rest of the day lol.

288 is the correct answer.

1. do ( ) 1st. Where anything in ( ) are to follow these steps. as if they where there own answer.
2. Then working left to right you do the following.
( * and % in order that they come up)
3. Then working from left to right again you do
( + and - in order that they come up)

I love the calc that all come up with different answer human error in the programming not a problem with the calc.

Never Question Google!

^^^^^

everybody arguing over middle school math xD

Hopefully people can start arguing over the order of the planets next :o

pluto isn't really a planet >:U

Gotta love the 2 different answers from 2 different calculators hehe

You so win the entire arguement :D

It's -1! Ask Gigiboo!

÷ could be viewed as a / however, for the rest of the equation, brackets would not be required.


It's not clear, that's the point.

That divisor sign can easily be

48
_______
2 (9 + 3)

That is writable without brackets.

That being said, I personally go w/ the 288, its just the question leaves room for much ambiguity.

*Two pages later*

Civil discussions still?!

As written there is no correct answer. If you rewrite it you can come into two different answers depending on who is interpreting. In this instance we follow the GIGO rule (Garbage In Garbage Out) in which case we say no and don't bother wasting the energy to argue or call each other names.

The answer is Pi, jackasses.

That's not math. This is math.
