Come on Peter Beater, give us the answer YOU think it is.

I am betting on 2.

240?

sorry drunk, i was doing 9+1. so 288?

[87slutstang]

9.6? I don't know whats the answer!?!?!?!?!?!1?

[Skillz]

Its a trap.

The correct way to write that equation is (48 / 2)(9 + 3) which = 288.

You can write it this way, but you gotta do the math in the correct order. Remember, from left to right.

48÷2(9+3)
48÷2(12)
24(12)
288

Besides, who uses a ÷ anymore? It's /. Geez,

[joel98gt]

No. The correct response is the order of operations, or PEMDAS. Parenthesis, exponents, multiply, divide, add, subtract.

2

[87slutstang]

damn, really drunk, I don't know how i got 9.6. but my guesses now are 288 or 2

[sapperstang78]

288. Order of operations. You do the addition in parenthesis first.

No. Your order of operations should look more like this PE(MD)(AS) As Parenthesis and exponents are the only ones you do in order. Then Multiplication and Division have the same weight, so you do them next from left to right. Finally addition and subtraction have the same weight and you do them from left to right.

What you are saying is that if I have 6-3+2=1, and that is not correct. You go left to right when the weight is the same. The answer to that is 5.

I'm seeing it this way also.

48 / 2 (9 + 3)
48 / 2 (12)
48 / 24 = 2

WUT?

[SATURN5]

Okay, the answer is 2, everyone. Look, a math problem can be solved in many different ways, and you’ll get the right answer every single time.

The controversial PEMDAS, BOMDAS way:
48÷2(9+3)
48÷2(12)
48÷24
2

The 2(12) has to be together, not because I’m prioritizing M over D. It is because it is altogether, just as 2x would be. (I will explain this further under substitution.)

DISTRIBUTIVE PROPERTY, which is for those who don’t know, A(B+C)=AB+AC:
48÷2(9+3)
48÷(2*9+2*3)
48÷(18+6)
48÷24
2

SUBSTITUTION, which in this case, we will substitute x=(9+3):
48÷2x

You don’t do 48÷2 first because there’s a variable there and get 24x. First, you find the x:
x=(9+3)
x=12

So, now, you have 2x.
2x=24
48÷24
2

If you want to take the SUBSTITUTION further, you can make it that y=48 and x=(9+3).
y÷2x

2x is together. The only way y÷2 could be a fraction is if it’s (y÷2)x.

Another way to use SUBSTITUTION, using PEMDAS/BOMDAS as well: This is why 2(12) is together. Let’s substitute x=12, assuming we have already added what’s in the parenthesis. 9+3=12

48÷2x; x=12

You can’t assume that (48÷2)x. That’s an entirely different problem. First, you have to find 2x.
2x=24
48÷24
2

Using the CALCULATOR, you have to recognize that 2(9+3) is together, so you have to type it like so:

48÷(2(9+3))

Otherwise, it naturally assumes you want (48÷2)(9+3).
It’s similar to how you use boolean phrases on a computer in terms of computer programming and even a simple Google search. If you want to search for “new Mexico laws”, as in the Mexico country’s laws, you would type “new Mexico laws”. But if you want to search US state New Mexico’s laws, you can’t just capitalize the “n” and assume the computer would recognize the proper noun. (i can just type like this with no capitalization or commas and the computer wouldn’t care.) You have to put parenthesis around “New Mexico” like so: “‘new mexico’ laws”. That’s because “New Mexico” is one whole idea just as 2(9+3) or in substitution, 2x is one whole idea.

WHY 288 IS WRONG:

By COMMUTATIVE PROPERTY, which is AB=BA, those assuming that we have to do the problem LEFT TO RIGHT is also assuming that the problem can be like so:
(48÷2)(9+3)
(9+3)(48÷2)
12*24
288

If you want to work by THAT, then, you’re assuming that this problem is the same as the original:
9+3(48÷2)
9+3(48÷2) ≠ 48÷2(9+3)

That’s a completely different problem, and this would get a completely different answer besides 288 and 2. (The answer is 81.)

THE ANSWER IS 2.

Best explanation I've seen...

[67mike]

I say 2.

Rule of order is BEDMAS

1) Brackets
2) Exponents
3) Divison
4)Multiplication
5) Addition
6) Subtraction

[Bobert]

Hi, engineer here. The answer is 2. See big ass solution above.

2(9+3) is one term. Brackets imply external multiplication. And show a precedence after inside the brackets are calculated.

You can write it this way, but you gotta do the math in the correct order. Remember, from left to right.

48÷2(9+3)
48÷2(12)
24(12)
288

Correct.

Mult & Div have the same weight so the ops are executed from left to right.



... and I do call "Shennanigans" since nobody would mix the math nomenclature of an implied multiplication with a '÷'.

In the real world it would be written 48/[2(9+3)], the answer to which is 2.
Per PEMDAS 48÷2*(9+3) is solved as Skillz showed us.

I've never heard of the multiplier before a parenthessis giving precedence.
It does make sense. Links?

Order of Operations - PEMDAS

288

wikipedia showed the answer to the posed question as "288", but listed it under "exceptions".
... haven't found anything about parenthessis bestowing precedence. Anyone?

What I recall (mind I'm pushing 30 years since my last math class) is that you have to work out the parentheses first, including any multipliers prior to moving any further into the equation.

That 2(9+3) needs to be reduced first then using the result as the divider to 48.

That said..

48/2(9+3) = x

48/2(12) = x
48/24 = x
x = 2

The Order of Operations: More Examples

This next example displays an issue that almost never arises but, when it does, there seems to be no end to the arguing.

Simplify 16 ÷ 2[8 – 3(4 – 2)] + 1.

16 ÷ 2[8 – 3(4 – 2)] + 1
= 16 ÷ 2[8 – 3(2)] + 1
= 16 ÷ 2[8 – 6] + 1
= 16 ÷ 2[2] + 1 (**)
= 16 ÷ 4 + 1
= 4 + 1
= 5

The confusing part in the above calculation is how "16 divided by 2[2] + 1" (in the line marked with the double-star) becomes "16 divided by 4 + 1", instead of "8 times by 2 + 1". That's because, even though multiplication and division are at the same level (so the left-to-right rule should apply), parentheses outrank division, so the first 2 goes with the [2], rather than with the "16 divided by". That is, multiplication that is indicated by placement against parentheses (or brackets, etc) is "stronger" than "regular" multiplication. Typesetting the entire problem in a graphing calculator verifies this hierarchy:

calculator screen-shot: 16 / 2(8) = 1, but 16 / 2 * 8 = 64

Note that different software will process this differently; even different models of Texas Instruments graphing calculators will process this differently. In cases of ambiguity, be very careful of your parentheses, and make your meaning clear. The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations. But not all software is programmed this way, and sometimes teachers view things differently. If in doubt, ask!

Final answer. 2

[P63]

I didn't notice the OP.

I just realized that this problem is listed under "Troll Math".

[Pete Butter]

48÷2(9+3)=48÷2x12=288

That's my answer

[MFE]

The ####ing plane takes off, dammit.

Like most things you believe, is incorrect.

[kim]

Its 2 in the real world, also got 5 in the other one, parens, then brackets, then multipliers/divisors of such numbers, thenstandard math left to right.

I think 288 and 2 are both correct according to this...

You can't have two "correct" answers if you follow the rules correctly. Read the bold part of my post above.
