Solve 48

[joint]

their is no argument for the other side. the other side is wrong, and the eqation is fine. if the other side was right... the equation would look like this 48/2*12. but its not. its an algebra problem because of the parenthesis which means you use the distributive property. a(b+c) = a*b+a*c. You guys will understand this when you finally take algebra for the first time ;)

mathematics is not a subject of opinion -

The majority of the people here right and the calcs agree with them. Calcs are based on programming done by people much smarter than all of us. Either the mathematicians that were involved in programming every scientific calculator are wrong or the few that are saying 2 are wrong. My money is on the calcs and my teachings which agree with the calcs.

the majority of people in here are wrong, and the calcs are putting out the answer for 48/2*12, which is not the equation listed above. the mathematician who programmed the calc was right, its just the user of the calc who is wrong. I bet you dont make money gambling.. do ya? if you type in the problem correctly you will get the correct answer from the calc. the correct way is 2(9+3), then 48 / the answer u get.

anyway, its all good. im not going to convince you - im sure one day you will find out the truth. I love you guys... I will talk to ya soon!

Why are there 24 pages for a simple math question? The answer is 288.

48?2(9+3) - brackets first

=48?2(12) - then left to right

=24(12)

=288

+1

:s

We should make this a poll :shifty:

[Hardcore Til I Die]

To sum up the answer is 288. B)

You go about this post as if you are so right, but where is your proof? More to the point: how does the multiplication [ ie. 2(12) or 2*12 ] get solved before the division [ ie. 48?2 ]?

As stated so so so many times, math is not a matter of opinion. Period. End of story. If you don't agree with the answer, you are not understanding the rules of the game.

[fintechfooty]

Yeah...you think you got me huh? BEDMAS BABY! :devil: :devil: :devil:

Lets see first we deal with some brackets.....(9+3)

Alright so we got that out of the way, OH no exponents :cool:

We're going to have some fun and divide...48?2 =24

Solid solid going strong!

Now we're left with....24(12)

= 288

SOLID work! I'm so bored that I made math fun.. :blink:

Also, it should not matter if you divide or multiply first due to the cumutative property of multiplication. We're dividing by two in the problem, not multiplying. If you want to distribute the two first through the parens then you need to multiply the 9 and the 3 by a half and not a two becuase it's "/2" and not "*2".

The "48" and "(9+3)" are in the numerator of the problem and the "2" is in the denominator. If it was desired for the "(9+3)" to be in the denominator then it should have been specified by placing parens around "2(9+3)"

Okay you're right, the order of operations is wrong.. when you finally take basic maths for the first time.. watch yourself get an f.

You see? There are arguments for both sides. The more I think about it the more I think that it's an incorrectly written equation. The distributive property means you need to simplify 2(9+3), BUT, that goes against the order of operations because you are solving a multiplication on the right before you solve a division on the left.

I think it NEEDS to be written as either 48/(2(9+3)) OR 48/2*(9+3), both of which can be solved without ambiguity.

It seems like a contradictory equation.

Interpreting it as 48/2*(9+3) ignores the distributive property.

Interpreting it as 48/(2(9+3)) ignores the order of operations.

No it doesn't.

Apply the law of distribution to the following equation: 48x*(9+3)

result = 48x*9 + 48x*3

x = 0.5

The answer is 288 anyone who says otherwise doesn't know algebra.

my proof is right here.... http://math.about.com/od/algebra/a/distributive.htm read this part The Distributive Property in ALgebra:

The Distributive Property is handy to help you get rid of parentheses.

a(b + c) = ab + ac

You should be distributing "0.5" in the parens and not "2" due to the division symbol before the two.

Please solve:

288 = 48x(9+3)

and

2 = 48x(9+3)

so now u got 48/18+6 im not changing ops. im still working within parenthesis now that they are gone --- simplifying after u do the distributive property properly, that number is 24. 48/24=2

18 + 6 simplified is 24, 48 is on the other side of the equation and is already simplified. both sides are now equal so u can now go left to right

You should be distributing "0.5" in the parens and not "2" due to the division symbol before the two.

Please solve:

288 = 48x(9+3)

and

2 = 48x(9+3)

the division symbol has nothing to do with it. the distributive property is a(b+c) 2(9+3) that is what u deal with first.... you ignore the other half of the eq until this half is totally solved. which is 24

The symbol before the two has everything to do with it. Those symbols are called operators. It's what we're doing to the numbers. The operator before the two is a division symbol. So we're dividing the equation by two and not multiplying it by two.

288=48x(9+3) => x=1/2

This matches our original equation

2= 48x(9+3) => x = 1/24

This does not match the original equation.

48/2(9+3)

(9+3) = 12

48/2 = 24

24 * 12 = 288

i see what you are doing. i understand how others are coming up with 288. i just dont think thats right. i think you do the distributive property first. 50% seem to agree with me

you guys are basically rewriting the whole equation first. 48*1/2*12 = 288. this is a tricky problem. I could be wrong, and I will do some research. But when I was in school and we did algebra... we always did the destributive thing first. If i am wrong, i will admit it.

It is right though. Plus MathWorks, Texas Instruments, and Microsoft all agree with us and they employ Ph.D. mathematicians to devise the calculator software and it agrees with what we are doing.

The answer is 288.

To make it more clear, instead of typing the equation linearly on the screen write it in fraction form on a piece of paper. You start with the number 48 as the numerator. Then we see the division symbol so we know that the 48 is divided by it. So that puts the 2 in the denominator of our equation. Then we see the "(9+3)" and we must ask ourselves what is this parenthetical equation doing in our problem? We are multiplying it to our problem due to the assumed multiplication due to the parens. Since we are multiplying it to our equation then the "(9+3)" will go in the numerator. This will make our numerator be "48(9+3)" and our denominator be "2". Solve this and the answer is 288.

There is nothing tricky about it.

http://www.themathpage.com/aprecalc/algebraPre.htm

If p and q are statements (equations), then a rule

If p, then q,

or equivalently

p implies q,

means: We may replace statement p with statement q. For example,

x + a = b implies x = b ? a.

That means that we may replace the statement 'x + a = b' with the statement 'x = b ? a.'

The algebraic definition of division

a/b = a * 1/b

Division, in algebra, is defined as multiplication by the reciprocal.

it is a little tricky. i will ask my step father tomorrow. he has a masters and was like an engineer for 35 years. expert in math. If im wrong, i apologize. I understand all that other stuff. i know that 3-2 is the same as 3+-2 and 48/2 is 48*1/2

[anarkhy]

The same equation is found all over the internet with google and also youtube

[joint]

I spoke with my step father... he says its 2. he says in any problem with the parenthesis.. you have to do the destributive property first. he said you cant just do 48*1/2*12. so he says its 2.. i say its 2... and the guy who posted above me on the calculator says its 2

[nub]

yea thats wrong. (9+3) = (12) the brackets are still there. they have to be gone before u continue. 12 inside the bracets means it is multiplying by something(keep simplyfing) . I know what you are saying, you are just wrong. you are just making up your own rules. I dont think you ever even took algebra before ;) the order i suggest is p first... you know, pemdas

You do stuff INSIDE of parenthesis first, not things next to it.

[Black Flash]

My god...This thread is insane.

288! Peace!

[Astra.Xtreme]

The answer is 288, no exceptions...

Distributive = multiplication

Order of Operations states that Multiplication & Division are executed from left to right.

Once you do the math INSIDE the parentheses, they disappear.

Hense, basic 2nd grade math states that the answer is 288.

good gawd this is still going on? maybe we need donald trump to go investigate it? sheesh... the answer to anyone who knows algebra is 288 and only 288 anything else is WRONG
